Round 2, May 26
W\: Thomas Hsiang 7d (US)
B\: Thomas Debarre 5d (France)
Commentary by Michael Redmond 9P
Transcribed by Chris Garlock

I know both players\; Debarre was in Japan recently, I think, studying, though I don't know the details. Hsiang is a longtime friend of my wife and her sisters, so I know him well\; he's a strong amateur. When I saw him the night after this game, he was saying that he had a fairly bad case of jetlag.]EV[WAGC 2010]PM[2]PB[Thomas Debarre]US[Transcribed by Chris Garlock]PW[Thomas Hsiang]FG[259:]WT[US]OT[3x30 Byo-yomi ]BR[5d]KM[6.5]AN[Michael Redmond 9P]RU[Japanese]

;C[This is modern variation that's quite popular nowadays. Many amateurs will instinctively hane underneath but this is a mistake (see var)]W[gq]
(
;LB[er:A]C[The game move at A is not the newest variation. This is interesting, because Thomas Hsiang was asking me before the tournament to tell him about new moves, and maybe it's a good thing I didn't, because this move turned out better than the modern variation]B[dp]
(
;LB[dr:A][fo:B]C[B's game move at A is conservative and doesn't pressure W\; I'd play at B, which has a number of follow-ups (see variations)]W[er]
(
;B[dr]
;W[eq]
;B[bp]
;LB[dr:A]C[This development illustrates the problem with B's move at A\; W got to play on the left and can live on the right anytime.]W[cj]

;B[qi]
;W[nd]
;B[pf]
(
;LB[pg:A]C[Jumping in the corner at 20 is another innovation we see a lot in recent games. The previous normal joseki, of course, is the hane at A]W[qc]
;B[pc]
;LB[of:A]C[If B plays at A, the joseki reverts to the old joseki, which would be bad for B]W[pg]

;C[this sequence is being played in a lot of pro games\; I'd prefer to play as B but some top players seem to think it's an even fight]W[pi]

;LB[ob:A]C[I was suprised to see B start the ko immediately\; it would be feasible, instead, for B to protect the corner with the move at A, taking away W's eyes, and wait to start the ko later]W[db]

;B[pj]

(
;LB[ob:A][jf:B]C[Again, I'd like to play at A for the reasons I just mentioned. B is worried about W's turn at B, but it's not urgent because W cannot enclose B]B[ig]

;C[very interesting move\; B's trying to take away W's eyes and take advantage of W's liberty shortage to capture W's 5 stones in the corner. For W, this is a good opportunity to switch to attack the upper side instead (see variation)]B[la]

(
;C[B needs to play this move to protect his upper side]B[gf]

(
;LB[rj:A]C[B is trying to take W's eyes, but W's follow-up is very good and W had no trouble living here. B would be better off starting at ko at A, since B has ko threats on the left side]B[qh]

(
;LB[nk:A][lo:B]C[W has a potential back-up eye in the center at A, so this move actually loses 4 points locally. Playing at B is much better]W[rm]

;C[Now B has gained an enormous amount in the center\; the two marked moves netted B about 10 points profit, erasing W's lead and making the game very close. Subsequent moves omitted\; W ended up squeaking to a half-point win in the end.]B[ln]TR[rm][nn]
