- Hi all!
-
- It's been a long time again, but no matter. Here is the very latest
- game, and boy have I been trying to get it ready before Christmas! Even
- if a little late, I think it is a fitting Christmas present to all
- interested (well, ok, you can call it New Year's present if you wish :-)
-
- This game is #30 Celebratory Issue, and the third bunch of ten has been
- sent to Adrian Marino for archival: it will be found at some later date
- by anonymous ftp at ftp.u.washington.edu at directory /public/go/games
- under name amgames3.sh.Z. *NOTE* that this bunch contains, as per my
- memory, some commentaries that have had only a limited distribution.
-
- The commentary of this game seems to be the most exaustive so far, and
- special attention has been put into the early fighting, and fuseki.
- Also lots of variations have been included, all with an explanation of
- some kind. I have been trying to make this as comprehensive as I can,
- but as everyone knows, goals are never completely achieved.
-
- The game is from the IGSWC, or Internet Go Server World Championship,
- and features, besides the usual number of mistaeks, some very most
- interesting fighting. The players are Gozilla 2 kyu (black) and Thor,
- who announced his rank as 5 kyu when entering the tournament.
-
- Thor was, BTW, somewhat amazed when I asked his permission to comment
- and distribute this about how I can get my hands to about 6 months old
- game...
-
- I have left lots of kibitzes there to give a feel of a tournament game,
- where lots of people go ahead and discuss the game, but even so I think
- I edited out about half of what originally was there.
-
- Merry Christmas and happy New Year. Have fun and enjoy!

-
- White loses on time.
-
- Commentary by Tero Sand, 2 kyu, and Olli Lounela, 3 dan.];B[dd]C[OL: This
- move has traditionally been considered unpolite. It's normal to start at the
- top right, and usually all diagrams are also printed that way.];C[TS:
- Kajiwara once called this 'a losing move', but that might be a bit extreme.
-
- OL: Extreme it is. Professionals, not to mention pro 9 dans, dispute this.]
- W[qd];B[dq];W[pq];B[dk];C[TS: I would be inclined to play 'a'.
-
- OL: 'a' would be the normal move, and would seem the best, though any shimari
- would be just about as good.
-
- However, if white plays at the bottom, it should be at 'b'.]L[oc][jp]W[jq]
- ;C[TS: Again, I would choose 'a'.
-
- OL: It would be clearly better.
-
- If black wants to play a kakari here, a bit further away from the corner
- would be better, eg. 'b'.]L[od][qn]B[qo];W[qm];L[pm][oo][op]B[pn]C[TS:
- Doesn't seem to be joseki. 'a' seems to give a reasonable result for Black,
- while 'b' or 'c' don't seem to work well.
-
- OL: This is nowhere near joseki, for white gets too good a result from simply
- pushing up.
-
- It's not easy, however, to say just what I'd do. 'b' is probably OK.];W[pk]
- L[pm][nq]C[TS: 'a' is more usual. Perhaps White is afraid of a Black pincer
- around 'b'...
-
- OL: This clearly is a mistaek. White should play at 'a'.];B[nq]C[TS: .. which
- comes anyway. However, maybe it is an overplay.
-
- OL: This pincer would seem a bad overplay. 'a' would seem better.]L[np];W[op]
- ;C[TS: 'a' seems better.
-
- OL: Not at all. It all depends on what black is trying to do.
-
- Actually, 'a' would be bad since white has the marked stone in a place which
- would prove to be the vital point \(makes 'b' possible later\).]L[rq][ro]
- B[qq]M[qm];W[qr];B[pp];W[rq]L[oq]C[TS: I would think 'a' is good enough,
- however, now Black seems to be in trouble.
-
- OL: This is the normal, correct style. White seems to have nothing to fear
- from black's cut at 'a'.];M[oq]L[rp][qp]B[oq]C[TS: This would seem to be
- dictated by fighting spirit, but the result wasn't too good. However, 'a'
- \(ko\) doesn't look good, while 'b' is horrible.
-
- OL: It's pretty hard to say which is the best way here.
-
- 'b' is absolutely out of the question. White would connect out at the marked
- stone and leave black eyeless and heavy.
-
- 'a' seems also out of the question since black has no ko threats.
-
- This would seem to leave the marked stone as the only possibility. Looks like
- black has to grit his teeth and be patient, but it does not look like black
- could get a good result here any more.];W[qp];B[no]L[np]C[TS: This shows the
- predicament Black is in.
-
- OL: 'a' is better. See variation B.](;L[np]W[po]C[TS: I would call this a
- good result for White.
-
- OL: White should push out at 'a' first.];C[TS: I think I would prefer 'a',
- playing ko if White cuts at the marked stone.
-
- OL: Perhaps you would. Both are pretty horrible.
-
- Black should play at 'b' and try to save the group while leaving some
- prospects for an attack at the bottom.
-
- Now black only gets split and weak. This is, BTW, why both should have taken
- 'b' at the earliest possibility.]M[qn]L[oo][np]B[qn];C[OL: Now white is bound
- to get a good result.]W[np];B[mp];W[mo]C[TS: Now Black's position is in
- shambles.
-
- OL: Good. The other cut would be worse since it would let black sacrifice two
- stones and connect here.];B[nn];W[lp];B[mq];L[mn]C[OL: 'a' is much better.
- Furthermore, it will remain the vital point for the next few moves.]W[lq]
- ;B[rp]L[rn][pm][nl][mn]C[TS: Black wants to get a stone at 'a' in sente, but
- I don't like giving White more territory/eyes. I would play 'b', followed by
- 'c'.
-
- OL: This is a huge-ish mistaek. Black should atari at 'd' immediately, before
- white gets a chance to play there. 'd' is similar in intention to 'b', but
- better.];W[ro]C[OL: Not necessary as yet. Better to push at 'a'.]L[mn];B[rn]
- C[OL: Still 'a'.]L[mn];W[sp]C[OL: 'a'.]L[mn];B[iq]C[TS: Dubious, while
- Black's group is weak.
-
- OL: Right-o. Black has to do something pretty good, and this at least shows
- spirit, but anyway it isn't any good. This only succeeds in splitting the own
- position.
-
- 'a' is still the vital point.]L[mn];W[mn]C[TS: This would seem just to help
- Black, although it's hard to say what else to do. I'd probably play 'a'.
-
- OL: Far from helping black, it prevents black from helping himself in sente.
- 'a' would be mediocre at most, and would yield the initiative to black's
- hands.]L[ir];B[nm];W[mm];C[TS: This seems risky.
-
- OL: Right, it's an overplay. Black cannot afford to create cutting points
- this way. I'd play at 'a', see variation B.]B[ml]L[nk](;C[TS: This looks
- risky, too, but is probably correct.
-
- OL: This is the correct way to punish black's overplay.]W[nl];B[lr];W[kr]
- ;B[ol];W[nk];B[ok];C[TS: An uncompromising move, though I must say White's
- position looks shaky.
-
- OL: There is no need for white to compromise. Catching the group secures lead
- in a most effective way.]W[oj];C[TS: Black sacrifices his right side group in
- order to try something with his lower side group.
-
- OL: It seems that there is little else black could do, but giving up 9 stones
- and 40 points with no compensation whatsoever is painful to say the least.]
- B[mk];W[nj];B[oo];W[pp];B[lo]M[mp][mq][lr][nq][oq]C[TS: Black is trying to
- free the marked stones, but this shouldn't work.];W[kn]C[OL: Good.];B[ko]
- ;W[jo];B[jp];W[ip]C[TS: Looks like a mistake - White's best policy might be
- to play as in variation B.
-
- OL: This is not a mistaek. White captures the cutting stones, and that is a
- good result. Black's cut has been made bad, an aji-keshi.
-
- Giving up the connection as in variation B is bad. One's aim should not be
- seeking independent life but to connect one's groups.](;B[jr];W[kp]C[OL: This
- is a good result for white.];B[ks];C[TS: I would play 'a'. This results in
- Black resquing his stones, which makes up for the loss on the right. However,
- White ends up clearly in the positive with his central thickness.
-
- OL: 'a' would not be better at all, since capturing the ko \(the marked
- stone\) is sente against the three white stones. See variation B.
-
- White should capture the cutting stones at 'b', which also would render the
- ko one sided, a burden for black only.]L[ir][ln]W[mr]M[kr](;B[kq];W[jp]C[OL:
- Capturing at 'a' seems better.]L[ln];B[nr];C[TS: 'a' seems better.
-
- OL: Not only seems, it is. However, if white plays 'a', the marked stone is
- made superfluous, and would be better used in reducing aji by capturing at
- 'b'.]L[kr][ln]W[ms]M[jp];B[ns];W[ir]C[OL: Too late now.];B[hq];W[kr];B[js]
- ;C[TS: This just increases White's loss.
-
- OL: White misses a tesuji. 'a' would either rescue the white marked stone
- \(variation B\), or seal black in \(variation C\).
-
- However, white needs to secure the big group above before playing at 'a'. I
- would recommend 'b'.]W[hr]M[ir]L[gq][kl](;B[gq];W[gr]C[OL: Now there is no
- way white can do anything in the bottom. White's loss grows with every single
- move.];B[fr]L[fq]C[TS: Correct. If 'a', White can get a ko as shown in
- variation B.](;C[TS: It's hard to see what White is after here.
-
- OL: Probably sounding out black's responses. However, this just loses what
- little potential there was. Better to play elsewhere.]W[fq];B[fp];W[er]C[OL:
- <Ouch!>];B[eq];W[fs];B[fq];L[oc][fc][pj][nc]C[TS: I think Black's group was
- already dead, so 'a' or 'b' seems more appropriate.
-
- OL: So it is. I'd play 'd'.
-
- However, as white is far ahead and seems unsure as to the status of this
- black group \(probably worried about the aji of the cut at 'c'\), I'd say
- better safe than sorry.]W[om];B[lc]C[TS: This looks strange. Black might be
- reasoning that if White pincers, Black can extend to 'a', but I don't like
- this. I'd prefer 'a' or 'b'.
-
- OL: 'b' looks OK.
-
- If black plays at 'a', he's sure to get pincered, and that is no good with
- the strong white position below.]L[oc][jc];W[cf]L[oc][id][fc]M[cf]C[TS: My
- instinct would be to play 'a', but then Black would have the incentive to
- defend, say, at 'b', which would make playing at the marked stone that much
- more difficult.
-
- OL: I would invade the other, larger side, at 'c'.];C[TS: I would prefer 'a'.
-
- OL: 'a' is not as good as the actual move. White would have the chance of
- attaching at the marked stone and that would seal off a large side.
-
- This actually is locally a good move. However, it seems to me that 'b' is
- more urgent. 'b' is, BTW, the second vital point repeatedly missed in this
- game by both.]L[oc][ch]B[od]M[od];W[pf];B[qc]C[OL: This is dubious. Black
- should be satisfied with the exchange of the marked stones and play at 'a'.]
- M[od][pf]L[ch];W[rc]C[OL: 'a' would seem better.]L[di];B[pc];W[fc]
- L[re][rb][qe][di]M[lc]C[TS: 'a' or 'b' are joseki \(in which case the marked
- stone is too close\), but considering White's position on the right side I
- would be tempted to play here, too. However, Black has a nasty spot at 'c'.
-
- OL: Considering the strong white position nearby, the marked stone is in the
- exact spot where it should. A larger extension would be loose.
-
- Discarding the top right corner is a good idea, but the actual move is
- dubious. Even after another black move, the top will remain invadable. I
- \(still\) recommend 'd'.
-
- 'c' does not do anything much; the corner is actually small.];B[fd]C[OL: 'a'
- would clearly be better; it would leave the direction the wall faces for
- black to decide. Furthermore, it would actually make a wall.]L[ee];W[gd];B[fe]
- ;W[ec];B[dc];W[dg]C[
- pierre 10k: j17];B[ce]C[
- pierre 10k: well ok that is joseki too
-
- TS: It is not a question of what is joseki but what works considering the
- surrounding positions.
-
- OL: Anyway, this joseki seems better for white.];W[be]C[ pierre 10k:
- personally i think black shud have played attach n block joseki
- jwkim 6k: White should resign I think.
- pierre 10k: instead of attach n extend
- pierre 10k: white???? no way, white leads
-
- OL: jwkim seems to be badly worng. At the moment white has a huge lead.]
- ;L[df]B[bd]C[TS: 'a' is joseki.
-
- OL: A big mistaek. Black loses what little shape he had.];W[de];B[cd]C[
- pierre 10k: this joseki is perfect fr white. he lives in upper n escaping
- with left is no problem with whites center!
-
- TS: Well, this isn't joseki, as stated before.
-
- OL: Not any more. Now it looks like black will pay heavily for his error...]
- ;L[fg][ge]W[bf]C[
- pierre 10k: black played wrongly b16 shud be at d14
- pierre 10k: now white jumps to f13 \('a'\), black has to connect and white
- k17 or j17 -- game over for black!
-
- TS: 'a' might indeed be better.
-
- OL: ...but white lets him off the hook. White should play at 'b'.];B[ch]C[
- pierre 10k NO! he shud play light! ARGH!
-
- OL: Here 'b' is a vital point. Black should force with the sequence 'a', 'b',
- 'c', 'd', which leaves white eyeless, heavy and in bad shape.]
- L[id][ge][gf][he];C[TS: The marked exchange is now bad for White.
-
- OL: If white wants to play on this side \(even if 'a' is the vital point\),
- 'b' is better.
-
- Anyway, this move makes black 'c' impossible, so it's not all bad, just
- slack.]M[ch][bf]W[fg]L[ge][dh][id];B[gf]C[OL: Good. This may look strange,
- but there is no way a cut at 'a' would work.
-
- Pushing at 'b' would be much worse.]L[gc][ge];W[ic];L[ed]B[db]C[
- jwkim 6k: I think b is good in the status.
- JohnBate 2k: I just started watching this one. What a mess at bottom right!
-
- TS: Connecting at 'a' might be wiser.
-
- OL: Not necessarily. The cut is not urgent, and black secures quite a few
- points in the corner while actually threatening white's eye shape at the top.]
- ;W[ed]C[
- pierre 10k: yeah n u shud have seen it before white messed up n let b live
- in lower! black was dead on both sides
- pierre 10k: b has to look out for carpenters square now
-
- OL: This seems premature. White loses a liberty and that makes a big
- difference in eyes on the group at the top.];B[ee];W[df];C[TS: Good. This
- maneuver reduces White's eyes in sente.
-
- OL: Not so good. This is also premature. Black should play at 'a' and aim at
- stealing white's eyes with 'b'.
-
- This can only be justified if black is terrified of white 'c'. Nevertheless,
- 'a' is the vital point for influence and for safety of the groups.]B[gc]
- L[gg][hb][eb];W[gb];B[fb]C[
- JohnBate 2k: Sigh. This game looks like prime-time TV. Lots of senseless
- violence. :-\)];W[hc];B[eb];W[gc]C[OL: Black's cut and squeeze has gained him
- eyes in the corner, but has also strengthened white's group considerably.]
- ;B[gg]C[OL: The vital point.];C[TS: 'a' seems better.
-
- OL: True. Even if it is a shape that seems full of holes, there would be no
- way for black to utilize that.]L[fi]W[fh];M[ic][hc][gb][gc][gd][fc][ec][ed]
- B[ie]C[TS: This looks slow, however, the marked group doesn't look very
- healthy.
-
- OL: Slow it may be, but more importantly it is a mistaek in direction. Black
- should push at 'a' to further strengthen his own group and to make an attack
- even more severe.]L[gh];W[gh]C[
- pierre 10k: black has to kill something f hes going to win this game
-
- TS: White seems to be very confident of his top group. Due to the strength in
- the bottom middle I think this group is stronger.
-
- OL: This is a vital point. If white's group at the top succeeds in living,
- he's quite a bit better off for playing here.
-
- That does not make it any less risky, however. I would prefer defending the
- weaker group \(top\) and letting the stronger one \(left side\) to take its
- chances.];B[ig]C[OL: This does not even begin to try to kill the group at the
- top, and that means the marked stone has been made bad. To justify the marked
- stone, black should try to kill, by playing at 'a'.
-
- Nevertheless, it seems that killing the white group would be just about
- impossible.]M[ie]L[jd];W[kd];B[kc];W[jd];L[hh][ii]B[jc]C[
- tsand 2k: Hmm, what's going on?
- pierre 10k: hi fun with new kibitzers
-
- TS: 'a', strengthening the middle group, looks better. White has only one eye
- at the top anyway.
-
- OL: Almost there, but not quite. 'b' is the shape.];W[id]C[
- JohnBate 2k: White dead at bottom, black dead on right. Anybody's guess for
- the rest.];L[ge][ii]C[TS: White seems to be in trouble, however, 'a' is
- surprisingly damaging \(to Black\).
-
- OL: Bad. Trying to kill white is premature.
-
- Going for influence by jumping to 'b' would still be better.]B[kf];L[ld]W[ge]
- C[TS: This move causes damage to White's left-side group, but also reduces
- the healthiness of Black's center group.
-
- OL: This is a bad move, since it is white's sente any time, at least for the
- time being. Pushing at 'a' is the only move.
-
- The only possible justification for a move like this would be that white
- wants to play it as long as it is sente and were afraid that black would not
- answer it later. However, the effect is that the white group on the other
- side weakens considerably. Thus, it is not advisable to play this if not
- absolutely necessary.
-
- pierre 10k white dead on top???
- tsand 2k not yet
- JohnBate 2k But getting close
- tsand 2k has to push

- JohnBate 2k Looks like "last person to kill something wins" :-\)];B[ff]
- ;W[hf]C[OL: The same thing that applied to white's last move applies also to
- this move, only more so.];B[hg]C[
- tsand 2k: k18
- jwkim 6k: OK! for w. next H14.];W[he];B[ib]C[OL: This is a bad move. Black
- should play at 'a' to try and escape into the center. White's group seems to
- live anyway.
-
- After taking 'a' black would have some, although rather slim, hopes of
- attacking the other white group if white defends the one at the top.]L[ii]
- ;W[if]C[OL: Again bad style, this too is white's sente any time.
-
- White should still play at 'a'.]L[ld];B[je]C[
- pierre 10k: ok he got one eye but he has to run away
-
- OL: This is terrible. Black is forcing white to split black's own position
- into pieces, a course that leaves black with lots of eyeless groups.];W[jf]C[
- jwkim 6k: escaping is easy I think.
- tsand 2k: he might lose d14 \(left side\) in the process];B[ke];C[TS: The

- jwkim 6k: how Thor can see this panel

- wolfgang 15k: yep.
- tsand 2k: or n10...
-
- OL: White catches the tail of the group. This solidifies his lead.];C[TS: I
- think I would play 'a'.
-
- OL: Let's see. White has about 85 points, and black has 45 plus whatever he
- can make on the left side. This means that white has a lead of about 40
- points.
-
- I can see no way for black to make those 40 points. Perhaps it's time to
- resign, but if black wants something else, it has to be rather drastic.
-
- Nevertheless, black seems to need a move in the center. 'a' is too loose, so
- 'b' should be it.]L[hl][il]B[fj];W[hl]C[
- badook 1k: Thor can't see our kibitz.. only talk
-
- TS: White is going for the jackpot.
-
- OL: Nevertheless, white is taking unnecessary risk. Playing it safe would be
- the probable course to the victory.];B[gi];W[il];B[dh];W[fi]C[OL: This move
- loses a liberty and reduces aji.];C[TS: Better to play 'a'.
-
- OL: Not at all. Since there is the throw-in after black 'b', this does not
- actually affect the liberty situation.]L[eh][ei]B[gj];W[bh];B[ei]C[
- tsand 2k: hopeless
- noam 5k: how long will it take him to kill black in the center?
- tsand 2k: hmm.. right, a semeai...
- JohnBate 2k: Looks like white is ahead by a move, now.
- JohnBate 2k: But it could still be messy...
- badook 1k: e13
- wolfgang 15k: i dont think w is in danger, because he can play e10 in sente.
- tsand 2k: if w lives, b loses];W[eg]C[
- badook 1k: e13 first
-
- OL: Throwing in first would seem a natural move, but it nevertheless would
- not help any. Black would have two cutting points to defend, and would have
- to take gote. Now black gives an extra liberty and gains sente to play the
- vital point for the semeai...];C[OL: ...which is here. Now white's group
- cannot get more than 5 liberties.]B[bi];W[kk]C[
- jwkim: 6k K8 for b
-
- TS: Very good - this captures Black.
-
- OL: Even if there may be other moves to do the trick, this looks positively
- tesuji-ish. Clever shape, I must say.
-
- Note that the important thing here is to take one liberty off the black group
- in the center.
-
- Now white's lead is *HUGE*. This would seem a time for black to resign.
- However, white is in a bad time trouble, and since this is a tournament
- game...];B[jl]C[
- noam 5k: it certainly looks messy
- tsand 2k: w in time trouble...];W[jm];B[kl];W[km]C[
- JohnBate 2k: M9 too slow. Must be contact play. No liberties to spare.

- noam 5k: what's wrong with L10?
- wolfgang 15k: now its fine.];B[lk]C[
- godok 1k: l10 can lead to a ko
- wolfgang 15k: there is no way you can play 14 moves in 2 mins. its
- physically impossible :\(];W[kj]C[TS: Normally, this would settle the game.
- There's absolutely no way White can lose.

- OL: Except for... :-\)];B[lh]C[
- noam 5k: server trouble?
- godok 1k: it is too late to make a ko
- godok 1k: b die
- wolfgang 15k: b should resign.];W[ki]C[OL: It would be better style to make
- a snapback by playing at 'a'.]L[ik];B[qh]C[
- godok 1k: b has a chance to use time threat
- noam 5k: why did you say physically impossible?
- JohnBate 2k: Thor is in Australia. Could be more net lag than that.
-
- OL: Black tries to make use of white's time problem.];W[rf]C[
- badook 1k: godok: hmm it is sneaky..
-
- OL: I would prefer 'a'. Losing a bit of territory is a small deal; it's
- better to keep the group caught.]L[oe];B[oe]C[
- wolfgang 15k: with the lag, maybe 10 seconds a move = 140 seconds for 14.
- jwkim 6k: Is Thor really 5k ?];W[nf]C[OL: 'a' would work. Black's marked
- group doesn't have enough liberties to try anything.]

- ;B[og]C[
- wolfgang 15k: whow, what speed ....];W[ph]C[TS: Surrounding the whole right
- side should definitely seal the game.
-
- OL: Yes, but it is a pity to let the group slip away. Keeping the group
- caught while connecting out from the side \(even if it would let black live
- there\) would have been better.];B[ng];W[os]C[OL: Playing moves to win some
- time.];B[ls];W[mb]C[OL: This is clearly bad. White should push at 'a'
- instead.]L[mc];B[mc];W[jb];B[kb]C[

- jwkim 6k: very interesting];W[rb];B[qb];W[co]L[dm][el][bp]C[TS: Seems a bit
- deep. I would play 'a' at the most.
-
- OL: It certainly is deep. Anything should be good enough, however, so playing
- a simple move at 'b' seems a good choice.

- Another good choice, and perhaps a better one, would be to probe at 'c'.]
