AB[pc]
C[Q17 is black's first move.]
;
AW[pe]
C[The major point with Q17 is that it may be hit by White with Q15. This is the character of the Q17 point.]
;
C[This gives White reason to play in the Q4 corner.

Even though this is just a matter of style, this gives White some momentum. Even though it is only his first move of the game, momentum is something that can be had right from the openning. Momentum in the openning can matter, and it can matter a lot.]
AW[pp]
AE[pe]
;
C[C16, D16 are all considered fine for Black's next move.

D4 is another suggestion. This will 'mix it up a little'. 

To keep it simple, Black will play in the top right corner. C16 is selected as Black's move, as it ensures that Black will have some territory in the openning.]
AB[cd]
;
AW[dp]
C[To keep things straight forward, White plays D4. Another strong move may be R15.

This openning may be called the Shusaku openning.]
;
C[Q6 and R6 are suggested moves for the next openning.]
;
AB[pn]
C[Q6 is a specialty openning.

This should only be used in special circumstances.]
;
AB[qn]
AE[pn]
C[R6 is the normal approach.

It is important to get used to playing in the normal way, only deviating and using the specialty cases when the situation calls for it.]
;
C[A question is asked as to which side (left or right) is most important.

To determine this, we need to check the shimaris (corner enclosures) available to Black.]
AE[qn]
;
AB[ec]
C[E17 takes the corner, which is great, but it is facing White.]
;
AB[qe]
AE[ec]
C[R15 also gains the corner, but this time, it faces Black.

While neither move is a mistake, this shimari (R15) will be more straight forward, and easier to develop from.]
;
AW[ed]
C[White will then want to come in with E16, giving Black control of the game. This is to be expected, as Black did move first.

This can be considered the normal way at looking at the openning.]
;
AE[qe][ed]
LB[qn:A][qe:B]
C[Black is given the choice of next move as either 'A' or 'B'.

'A' is more active (rather than being more agressive) than move 'B'.

Someone remarked that they had heard that 'A' was better. Shygost says that this is wrong, that if anything, 'B' could be considered better. B is a more basic move (see the first lesson), that no one could say is a bad move. 'A', on the other hand, could be faltered.

According to Janice Kim's books, you should approach unbalanced corners first -- this is why 'B' is considered a basic move.]
;
AB[qn]
C[The class is divided; 'A' (R6) is selected as Black's move.

Someone asks if it is bigger than O3. Shygost says that it is a stylistic choice, that it is not a mistake to play O3 rather than R6.

A stylistic choice is made if it is a move you normally play, or if you feel like it at the time, when you're in the mood.

R6 is possibly easier to develop from. With R6, it almost looks like Black has taken half the board already.]
;
C[Shygost asks the question, should White pinch here? How should you choose wether or not to pimch?

After a number of responses from students (see the original SGF), Shygost says there is only one criteria in making this choice.

Which side is bigger?

If the side is bigger, we pinch.
If the bottom is bigger, we extend.
If they're even, whatever you are in the mood for.]
;
AB[qd][oc][on][qj]
AW[ql][np]
AE[pc]
LB[ql:1][on:2][np:3][qj:4]
C[If the upper right was altered, the R8 pinch would be a bad pinch. Black can then attack, whilst gaining points -- this is too much.]
;
AE[qd][oc]
AB[pc]
C[If we go backto the board position however, there is nothing special for Black here -- so it is okay to pinch with R8.]
;
C[So, you must ensure that your pinch is safe. 

To be certain, you may need to apply a loose pinch, like R11, as a 6-dan played against Shygost recently. Shygost did not feel that it was strong pinch, and that was the point -- the pinch was not to attack Black, it was to survive and live easily in Black's large territory.]
AE[qj][on][np][ql][pc]
AW[qi]
AB[qd][oc]
;
AE[qd][oc][qi]
AB[pc][qi]
AW[nq]
C[It is valid for White to extend with O3. But this allows Black to play R11, which makes Black's side very nice, as it works well with the top.

Black likes this, so White has the burden of stopping white from exploiting this.]
;
C[So a pinch is in order. 

Assuming that White pinches with Q9, and if we continue this joseki...]
AE[nq][qi]
AW[pk][qp][op][ro][qo]
AB[qq][pq][rp][rq][nq]
LB[qq:1][qp:2][pq:3][op:4][rp:5][ro:6][rq:7][qo:8][nq:9]
;
AW[qe][ph]
AB[od]
C[White may continue like so, which is good. White has no problems with this.]
;
C[If W pinches with Q9, and another joseki is followed...

Again, no problem. So both are playable.]
AE[od][ph][op][qp][qo][ro][rp][rq][qq][pq][nq]
AB[rp][on][rk]
AW[qq][np]
LB[on:A][on:1][np:2][rp:3][qq:4][rk:5][qe:6]
;
C[In order to choose, we must determine which is bigger.

This may look big for Black, but Shygost recalls that maybe 5 years ago, this setup would scare him -- he did not want to play against black in this way.

So he played this way *every, single time* for several years, until he was no longer afraid of it.

In both of the cases here (extend or pinch), they are even -- no one gets ahead.

 ]
AE[qe][rk][pk][on][qn][rp][qq][np]
AB[qn][qi]
AW[nq]
;
AE[qi][nq]
AW[qo][np]
AB[pn][pi]
C[R5 is *not* joseki, although many kyu players think that it is.

White does not get the corner, but Black gets something that is very nice.]
LB[qo:1][pn:2][np:3][pi:4]
;
C[R5 should only be played if White has a stone near Q10.

Now this is joseki, as White still does not get the corner, but Black didn't get anything nice either.]
AE[pi]
AW[pj]
AB[pl]
;
AE[pj][pl][pn][qo][np]
C[Shygost decides to play the simple way (extend).

The question is raised, if he is going to extend with O3, why not extend with N3 (the long knight's move).]
AW[mq]
;
C[The problem with the long knight's move, is that even if Black did not have a stone at R6, Black is able to invade the corner and live in sente.

If Black can live in the corner in sente, this would be a pretty serious problem. There needs to be a very serious reason for wanting Black to live in the corner for free.]
AE[qn]
AB[qq]
;
C[If the board looked more like this, then it makes sense for White to want Black to live in the corner. 

So the long knight's move should only be played for reasons of moyo, or if you are sure you are getting the corner and you want it bigger.]
AE[qq]
AB[ec][dj][qq][pq][or][op][rp][rq][pr]
AW[pe][pj][qp][oq][nr][nq][ro][qn][oo]
LB[qq:1][qp:2][pq:3][oq:4][or:5][nr:6][op:7][nq:8][rp:9][ro:10][rq:11][qn:12][pr:13][oo:14]
;
AE[pe][pj][qn][ro][qp][pp][op][oo][mq][nq][oq][pq][qq][rq][rp][pr][or][nr][dj][ec]
AW[pp][mq]
AB[qn]
C[In this board position, there is nothing to suggest that we want this, so the long knight's move is not suggested here.]
;
AE[mq]
AW[nq]
AB[qi]
C[ There is only one response for Black in the modern game, and that is R11, forming the mini-chinese.]
;
C[White will then approach the remaining corner.

Notice that Black has three stones on the right that he wants to grow.

So Black can play H16. This is very nice for Black, so White wants to avoid this.]
AW[ec]
AB[hd]
;
AE[ec][hd]
AW[fc]
C[White can avoid this by approaching from further away. This stops Black from simply ]
;
C[The question is asked of how Q10 compares with R11.

If we are only looking at R6 and Q10, these stones are very nice.]
AE[fc][qi]
AB[pj]
;
C[If the game progress like so, Black will be very happy.]
AB[qe]
AW[ec]
;
AE[ec][qe]
AW[qe]
C[But if White plays like so XXX.]
;
C[White also has the option of playing like this.

In other words, Q10 is not XXX.

In both cases, White will be able to live comfortably.]
;
AE[qe][pj]
AB[qi]
C[With R11, there is no place for White to play that is comfortable.]
;
C[If the top right was a Black stone on Q16 rather than Q17, Q10 is now prefered.

Now if White comes in with R14, it is difficult again for White.]
AE[pc][qi]
AB[pd][pj]
AW[qf]
;
AE[qf][pj][pd]
AB[qi][pm][nm][mm][no][pg][pc]
AW[ql][pl][ol][nl][oi]
C[R11 is okay, even if White comes in. Black has two options.

He can chase White like so. Black ends up safe. White ends up with a wall, but no eyes as yet. So White will not feel safe in attacking with it -- he must defend first.

So one wonders what White has accomplished.]
;
AE[oi][pg][ol][pl][nl][mm][nm][no][pm]
C[Black's other option is to just try and live -- this may happen later in the game.

White runs out with O8, Black also runs out with O11.

Both parties are fine.]
AB[qp][ro][rq][oi]
AW[ol][pq][qq]
;
AE[oi][ol][ql][ro][qp][pp][rq][qq][pq]
AW[pp][fc]
C[White's move is into the biggest area, with F17.

Black has several possible responses that are dicussed. These include D17, H17, D14]
;
AB[df]
C[D14 is a bad move. There is no pressure on White, and it is trying to develop in an area that cannot be developed.]
;
AE[dp]
AB[dp]
C[If D4 was a black stone however, D14 makes sense.]
;
AE[dp][df]
AB[hc]
AW[dp]
C[The pinch with H17 is possible.]
;
AE[qi]
C[However, if the board was slightly different (R11 was removed), the pinch has less purpose to it. It is still playable however. It just won't develop the right or top well.]
;
AB[qi][dc][kc]
AE[hc]
C[D17 is another possible move for Black.

A question is asked if D17 is 'less-active' with the upper right as robust as it is.

Shygost's reasoning is that because Go is damn hard, lets make a bunch of rules to use as a crutch to guide us. This is not the best thing, but Go is hard, so we need to do what we can. If you are going to be a Pro, and think through every move, then don't use the List.

In order to determine if D17 is too slow or if it is an appropriate move, a little reading is required.

After Black D17, White will extend, and Black will pinch immediately as White is tight.]
AW[ic]
LB[ic:1][kc:2]
;
AW[ie][mc]
AB[cg]
C[White will then come out with J15.

Black doesn't want to be surrounded, so he extends with C13.

White can then start in, with N17.

So according to this, D17 is a little slow. Black is unable to get the side that he wanted after playing this way.]
LB[ie:10][ie:3][cg:4][mc:5]
;
AE[ic][kc][mc][ie][cg]
C[If we play the other way, this time it is a little harder for White. It is not so easy to approach the right.

So White should play the other way.]
AW[jd][fe]
AB[lc][cg]
LB[jd:1][lc:2][fe:3][cg:4]
;
AE[cg][fe][jd][lc]
AW[ic][ie][cf]
AB[kc][md]
C[The other option to check is what happens if Black decides to defend with N16 rather than preventing the upper left from being surrounded.

In this case, Black will suffer too much as a result.

This is because Black has been greedy, playing stones where he wants them, rather than where the board wants them.]
LB[ic:1][kc:2][ie:3][md:4][cf:5]
;
C[So D17 does not help the right side as much as Black would have liked.

For amatuer play, both are fine however.

The option for Black to play is at 'A' or 'B'.]
AE[dc][ic][kc][md][ie][cf]
LB[dc:A][hc:B]
;
C[It is a resounding vote for 'B'.

White continues with C17.

'B' is by far the more normal way to continue.
But 'A' is playable.

We continue with 'B'. The following is joseki.]
AW[cc]
AB[hc]
LB[bc:A][dc:B]
;
AB[cb][dc][ec][ed][ef]
AW[dd][de][bc][bb]
LB[dc:1][dd:2][cb:3][bc:4][ed:5][de:6][ec:7][bb:8][ef:9]
C[This is joseki. 

While deliberately plays out with 9 at E14. This is weak on purpose.]
;
AW[ee][ce]
AB[fe][fd]
C[White can push with E15, creating two cuts, but knowing that black also has two cuts which White must fix with 3. Black can then fix with 4.]
LB[ee:1][fe:2][ce:3][fd:4]
;
C[Later on, Black has the option of playing C14, which is a nice forcing move.

This gives Black what he wants on top, and on the right.]
;
C[White's left sound is not all that special.

Eventually, White can cut with F14. But at the moment, Black can play on the left easily.]
AW[ff]
;
AE[ff]
C[Left is big, but top is biggest.

White would like to play a stone like M17, and have miai. He cannot, as there is not enough space for miai.]
AW[lc]
;
C[A suggestion is for White to reduce Black's potential territory.

This would look like this board. This is a reasonable continuation. However, Black is getting so much, and White is getting so little.]
AE[lc]
AW[id][kd]
AB[ic][mc]
LB[id:1][ic:2][kd:3][mc:4]
;
C[Instead, White plays at O17. With this move, White is stating that 'A' and 'B' are miai.

Possible moves for Black are R14, R15, Q14, Q15, O15, P15 and P16.

This is the sort of position that kyu players often get confused with.]
AE[ic][id][kd][mc]
AW[nc]
LB[pd:A][kc:B]
;
C[The first position to consider is R14.

R14 is very thin, and allows White to come in, and do almost anything, and white will be fine.]
AB[qf]
AW[qc]
;
C[It is the same sort of deal with Q14.

Here, White (O17) is one space away from Black (Q17). Black (Q14) is two spaces away from Black (Q17).

White is closer to Black than Black is. 

So this isn't good for Black. (Audio dropped out a little here)]
AE[qc][qf]
AB[pf]
;
AE[pf]
AB[qe]
C[R15 is a classic kyu move.

It is a bad move.

Firstly, R15 and R11 are both low. With this, Black is developing slowly, inefficiently.

Also, there is only very little pressure on White with this move.]
;
C[P16 is the answer.

This move allows Black to develop quickly, in sente.]
AE[qe]
AB[od]
;
C[White's response is next to Black's strength, so Black can laugh and say that White's move doesn't even effect him.

If Black continues with 2, he can create a very large development.]
AW[kc][mc]
AB[nd][oi]
LB[kc:1][nd:2][mc:3][oi:4]
;
C[O16 is too greedy however, contacting the weak stone.

Contacting a weak stone forces White to live, rather than having White play all the moves himself.]
AE[oi][nd][mc][kc][od]
AB[nd]
;
AB[oe]
AE[nd]
C[P15 puts less pressure on White. Black's aim is to keep as much pressure as possible on White while getting as much profit for free.
]
;
AB[pe]
AE[oe]
C[Q15 is better than R15. We have the 'classic' wave pattern, starting on the third line (Q17), moving out to the forth (Q15), and then back to the third(R11). This is good enough -- a success for Black.

But P16 is much better, Black is much happier.]
;
AE[pe]
AB[oe][md]
C[P15 is a mistake. Playing on the fifth line does not take points.

If play continues like so, Black does not take territory. His shape is very thin.]
AW[kc][mc]
LB[oe:1][kc:2][md:3][mc:4]
;
AB[od]
AW[nd]
AE[kc][mc][md][oe]
C[White continues with O16.

Possible next moves for Black include P14, P15, O15]
;
AB[oe]
C[P15 is a tiny step.]
;
AB[of]
C[P14 is better -- we can safely extend to here. When we have the option, we should extend as far as we can.]
AE[oe]
;
AB[ne]
AE[of]
C[If we are comfortable with O15, this move does a lot.

This is very fast, and applies a lot of pressure to White.]
;
AW[kc]
C[White plays L17 to be safe, and Black must now come back and protect his cut.]
;
C[If Black plays N15, this is not sente, and White will probably cut immediately.

White is fine on top, as there is plenty of room.]
AW[oe]
AB[me]
;
C[Therefore, we should protect the cut with P14.]
AE[me][oe]
AB[of]
;
C[It is also possible to play P12, but there is too much space.]
AE[of]
AB[oh]
;
C[P13 is almost okay, but White can play Q12. P13 seems to suggest that Black is connecting two stones, but in reality, is not.]
AW[ph]
AB[og]
AE[oh]
;
C[Therefore, it may be better to back off with P14, get a little bit stronger and not pretend to connect]
AE[ph][og]
AB[of]
;
C[P15 is a little slow. Black should try and come out as far as he can.]
AB[oe]
AE[of]
;
AB[of]
AE[oe]
AW[ic]
C[White plays J17.

Black's possible moves include N15, which is big. A move which responds to White's J17 is Black at J16.]
;
AB[me][of]
AE[ic]
C[Coming back to Black's move if he wants to protect the cut, we now consider what happens if Black does not protect the cut, but extends with N15.

White will immediately start something. Black does not want to play this way, as the corner may die.]
AW[oe][pe]
LB[me:1][oe:2][of:3][pe:4]
;
C[Therefore, Black will want to play this way.

While 6 is almost sente, let us assume that it is not, and Black begins to attack with at the top with 7 at K18.]
AE[pe]
AB[pe][pf][jb]
AW[of][og]
LB[me:1][oe:2][pe:3][of:4][pf:5][og:6][jb:7]
;
AW[jc][ke]
AB[ib]
LB[jc:A][jc:1][ib:2][ke:3]
C[White is very comfortable playing this way, even if he did not have the wall at P14. Black is in more trouble here than White.

So here, Black's extension with N15 does not do enough. It is better to protect the cut.]
;
AE[ke][me][ne][of][pf][og][oe][pe]
AB[ne][of][mf][lf]
AW[me][le][rp]
C[If Black waits until the cut is gone (by playing 1, and assuming White plays elsewhere, for example, S4) before begining his attack on White, Black gets large profit, while White barely lives, and gets only two points compensation.]
LB[of:1][rp:A][rp:2][jb:3][jc:4][ib:5][me:6][mf:7][le:8][lf:9]
;
AE[le][me][mf][lf]
AW[je]
C[If White chooses to run out with K15, this is very passive -- no pressure on Black, and it itself does not do alot.

This is all due to Black removing the threat of the cut, as White no longer has anything to counter an attack by Black.]
;
AE[rp][jc][ib][je]
C[If there is something urgent on the board (let us assume that a play by White at D13 is urgent), White can play it. Even if Black attacks the top White stones with K18, White will still survive -- but it is a poor life.]
AW[dg]
;
AE[jb][dg]
AW[ic][hb][gb]
C[J17 is important, because if Black ignores it and plays elsewhere, White is then able to continue in this way -- Black is not definitely alive, as he may only have one eye at the top now. So White at J17 affects Black significantly.]
AB[gc][fb]
LB[hb:1][gc:2][gb:3][fb:4]
;
C[In a short interlude, Shygost explains the difference between gaining 'profit' and 'territory'.

Territory are specific, countable points.
Proft is something nice too have (good things).

For example, non-countable points. Black's region A is profit -- it is not definite territory as yet. A nice thick wall is not points, but it sure is profit. A simple good peep, which is just a single stone with sente, could be considered profit, but definitely not territory.
]
AE[fb][gc][gb][hb]
LB[qf:A]
;
C[Most students suggested Black at J16 in response to White at J17. Shygost has some hesitations about this move.

J16 is playing very close to a thick wall for Black (F15 and F16). This is inefficient.]
AB[id]
;
C[Playing underneath, at J18, is not playing near thickness. Also, it is playing where the points are, underneath towards the edge of the board. It is also where White's eyes are.]
AB[ib]
AE[id]
;
C[If White submits by playing K18, Black is able to continue and get both (J18 and J16).

This board is terrible for White.]
AW[jb][jc]
AB[id][hb]
LB[jb:1][id:2][jc:3][hb:4]
;
C[White cannot allow the previous board, so rather than submit, White comes out.

A Black play at H15 is also playing close to thickness.]
AE[hb][jb][jc][kc][id]
AW[id][kc]
;
C[There is only one good idea for Black's next move, K18.

Other suggested moves include J15 and J14.]
;
AB[ie]
C[J15 is playing too close to White's thickness.]
;
C[Playing a cap with Black at J14, White can continue with K18 and will live at the top.]
AW[jb]
AB[if]
AE[ie]
;
C[K18 is an exceptional move.

It is mulit purpose -- it takes points, takes away White's life and it makes cutting points.

According to Shygost, when he first began playing Pros when he was 1kyu, he first started seeing moves being played like this. Amatuers may think of this move as just as 1 point, meaningless move. Stronger players, however, regard this as a profoundly powerful move.]
AE[if][jb]
AB[jb]
;
C[A student suggests that capping will lead to greater outside influence.

Shygost suggests that if he were to cap, he would cap using Black at K14. If the game follows as shown, White would liev at the top, and Black would have the most influence he could get from his position.

Ok, so the cap has produced outside influence for Black -- but for what purpose? Black has nothing in the center.]
AE[jb][ib][id][ic]
AB[cf][id][jf]
AW[be][hb][ib][ic]
LB[jf:1][hb:2][id:3][ib:4][cf:5][be:6]
;
C[If the board were more like this setup, then it makes sense for Black to create center influence. Now Black has every reason to want the center.]
AE[pp][nq][dp]
AB[dp][pp][nq]
;
C[In the current game however, there is no reason for Black to persue the center. It makes sense for Black to aim for the top and get points.

Before K18, White would have had about 8 points at the top. By playing at the top, Black has gained the G18 area (marked with triangles), worth 5 points. This makes a total of 13 points that Black is ahead due to this sequence, and it has not cost him a single move -- all moves have been sente.

13 moves for free for several moves adds up to a lot through the course of a game.]

AW[kd]
C[White defends with L16.]
;
C[White should not try and defend with L18.

Allthough Black's cut (L16) does not work yet, the problem is that there is a cut there.]

C[M16 is one way to abuse the cut.

This makes White into a completely eyeless group.]

AE[kd][ld][mb]
AB[le][nm]
AW[kd]
LB[le:1][kd:2][nm:3]
C[Or Black can play this way, which can be very beneficial.

And still, White has, at most, a single eye on top.]
;
C[Or there is this method, which threatens to kill if White saves -- the cut now works.

This is why to avoid weaknessess, as your opponent may be able to use them anytime they wish.]
AE[le][kd][nm]
AB[md][kd]
AW[mc]
LB[md:1][mc:2][kd:3]
;
C[White would be better playing in this way, but it involves White sacrificing two stone (J17 and J18), and a large number of points -- it is probably not worth this sacrifice just to allow White to get out with room and a few points.]

C[C14 raises an interesting point. C14 is a forcing move that Black can use at any time, but he needs to be intelligent in deciding when to do so.

White will respond with B15. Black connects, and White cuts with F14.

What did Black accomplish? Absolutely nothing, other than creating a weak Black group.]

C[If Black protects the cut before connecting, White can play like so. This raises the question as to what was the purpose of the C14 stone.

So Black should wait until it is the right time, when ]

C[O6 builds a moyo.

But according to a quote by Mr Yang, "when in the opening, play an opening move".

We are still very much in the opening of the game, so we should concentrate on playing opening moves first.]

C[The question is asked if White's top group can still be chased around, as it is not alive as yet.

The purpose of chasing these White stones will be for Black to gain profit (rather than just killing this group).]
AE[fp][fq][eq][dn][jq]
;
C[If the board followed this setup, it is definitely a good idea to attack the top. White will have a lot of trouble surviving there, and Black will get profit in the process.]
AB[lf][jg][lb]
LB[lb:1]
;
C[Returning to the current game, it is tough to say if White will have a difficult time surviving.

If Black attacks with L13, White can ignore -- Black's attack will not kill it straight away.

When Shygost was 4dan and playing stronger players, his attacks never led to anything. When he questioned these stronger players, they said that his attacks were not working because they were premature -- if you attack when you are not ready, when the attack is not real, then it is meaningless.

So Black should perhaps wait until he is ready before attacking this White group.]
AE[jg][lf][lb]
AB[kg]
;
C[A move around the White stone in the lower left is now big.

The left side is bigger than the bottom for Black. Looking at the bottom, there is no future there -- there is no White stone that could get weak, nor are there Black stones that can be developed.

Furthermore, White has a low finished group on the right (O3and Q4). When a move is played on the third line, this is considered a finishing move. White is effectively saying that he no longer wishes to grow this group -- if he continues with L3, this is a slow move.

So nobody wants to play on the bottom.]
AE[kg]
AW[kq]
;
C[The left side however, if White plays at F14, is huge. The side is only White stones, and it is six lines high.]
AW[ff]
AE[kq]
;
C[This is tremendous potential for White.

White is not likely to start by playing the cut at F14,  but the potential is enormous. White is able to grow big on the left.]
AW[dm]
AE[ff]
;
C[Looking towards Black's move, if he approaches with C6, White is likely to extend with F3.

Now it makes more sense for Black to use his forcing move at the top (although it is not likely he will play this immediately.

Now Black has potential on the left.]

C[A question is asked concerning the difference between C6 and D6 for Black.]
AE[fq][df][be][cf]
;
AB[bp]
C[When playing C6, Black has a follow up move wtih B4, which is a comfortable, strong, non-cuttable, forcing, settling move.]
;
C[With D6 however, Black is unable to get into the corner. He still has not even formed an eye as yet.

So this is a specialty move, when Black is prepared to give up the corner in exchange for getting something special on the left.]

C[So Black play C6.

White cannot yet develop the left side. Although he has the cut at F14, it is unlikely he will get the opportunity to use it.

If White cuts with F14, Black can continue like so, allowing White to take a large portion of the left. But this leaves White vulnerable on top, where White may die.

So we should consider F14 a false-cut.]
AW[ff][fg][fh][fi]
LB[ff:1][gf:2][fg:3][gg:4][fh:5][gh:6][fi:7][lf:8]
;
C[Because Black cannot develop well on the left, and White's cut at F14 is not practical at the moment, White plays a normal move, extending with F4.]
AE[ff][gf][fg][gg][gh][fh][fi][lf]
AW[fp]
;
C[The question is raised if Black at M14 should wait until White's top is more pressed in -- Shygost says that the reasons for playing M14 are for that, or if Black is ready to commit to the center.

If the game follows this continuation, L14 may be practical.

However, it is a bit too close to thickness.]

C[M13 may be better.

Now, if White starts entering (for example, P6), Black can begin some serious chasing along the top, which is difficult for White.

This is the last thing to be done in the game. Because the attack is not a strong attack, it should only be used towards the end to get points in the center. Getting points in the center is the last thing we want to do.

C[Possible moves for Black include C10, C4, D13, C9, H3]

C[C10 is not possible, as it is weak, and allows White in.

The C10 stone is now weak, so Black is left with two weak groups.]

C[D13 is playing lightly.

But it is difficult for White to take the C13 area at the moment, so there is no need to be playing so far.]

C[If we intend to extend, the safe way is to play Black at C9.]
;
AB[hq][en]
AE[ck]
C[H3 is too much.

White can immediately pinch, and Black is left supporting two weak groups.

There are two many White stones around to leave a weak stone (C6) and play another weak stone (H3).

If there were more Black stones in the area, Black could play more aggressivly.]
AW[ck][go]

C[Black needs to settle his C6 stone. It is normal to play 'A' in the corner first, then extend to 'B', but extending directly to 'B' is also playable.

To select, we must consider which is bigger, the side, or the corner.]
AE[ck][en][go][hq]
LB[bp:A][ck:B]
;
C[If White takes the side, the pattern will be as follows. This is good for White.

White's cut with F14 now has significance, and White would almost be prepared to play risky for a large reward. The bottom also looks very big now.]

C[F7 as a possible move for Black is considered, but  it would appear better suited if Black first played elsewhere and White tried a pinch (for example, D9) -- then F7 could be considered valid. With the current position, F7 is not valid.]

C[Because Black left the corner in preference to the side, White is able to take the corner by playing the kick with C5. Black settles himself with D6.

White can now take the bottom, which is nice.

But Black has just developed a new strong area which assists the Black stones in the top.

White feels the need to be secure, so he plays L18 to secure eyes.

It is now Black's move. Shygost explains the process by which potential moves should be refined and selected. Explaining this process is one of the major component of what Shygost's (private) lessons provides.

Follow the List!!!

1. How is Black? All around the board, Black's groups are fine.
   How is White? Because White just defended, it is unlikely that there is a possible strong attack on White at the moment.

2. What is big? In order to determine what is big, you need to count! There are 5 (or 6) main areas worth counting -- we need to determine which one is worth playing in.

First, we can eliminate region 6, as it is a small corner, clearly smaller than region 2.

LB[ci:1][cq:2][jq:3][ql:4][ni:5][qq:6]

C[Area 1 is hard for White to develop, and it is also hard for Black to develop.

Even if Black plays this way, White is able to stop Black getting huge profit. So Black must wait until he can develop this side into something that he likes.]

AB[cf][df]
AW[be][bg]
;
C[If White aims to develop Area 1, and plays away with 3, it is then a good time for Black to aim in that area. Black is able to remove this area in sente.

As neither Black nor White can take Area 1, it cannot be considered a big region to play in.]

C[Area 2 is not the biggest area.

More importantly, playing in Area 2 also hurts Black's region on the left, so Black should avoid playing here.

The process of comparing areas is identifying the character of different regions -- identifying who wants to grow, who does not want to grow, will playing in that areas hurt the opponent or your self.]

C[A better move is O7, which plays in both Areas 4 and 5.]
;
C[This leaves areas 3 (the bottom) and 5 (the center). From experience, we know that getting points in the center is tricky -- so we eliminate area 5, leaving area 3 as the biggest area to play in.

In area 3, there is only one place that is safe -- H3.   We know that it is safe because it has three directions that it is able to go if attacked. H3 has three options that it can do to ensure that it is safe. An option can include anything such as a powerful peep, a contact play, or simply an extension.

Thats all for today's lesson. Email shygost with comments, info about what you'ld like to see in the lesson, or if you are interested in taking private lessons with him.]
