I got a forfeit win for round I (which screwed my tiebreaks), so here is the first game I played in the open. I had it reviewed by a pro-- see if you can predict what they said.  I think if he had given me the two stones near the end it would have been a half point game. |

OK, I'll give it a shot, with a few comments on the opening. Move 11) B should almost certainly block at C4. Since B knows which side he wants to block, he should play there immediately. After W responds D3 (forced), B should hane and connect at B3. This is a fairly common joseki which properly emphasizes the left side for B. On the other hand, when B fails to block, I am not sure whether W should next play C4 or D3. Both look good for W. Playing at D3 lets W hane at B4 after B blocks, making the B capture of the C6 stone over-concentrated. If the pro commented on this area, I would be interested in his analysis. Move 21) B should just slide to S11, the joseki move to make a base for his group. W should ignore S17 to take a large move elsewhere. The exchanges S17-S18 and R16-Q17 are good for B (compare to a W move at S17 in the endgame). But B leaves this situation unsettled at move 25. Since W answered in the corner, B still has not established a base, and the slide to S11 is still required. Move 26) Right idea by W, but wrong execution. W should press the B group from the other side at R12, making territory while attacking. W needs to play on the weak side, forcing B to run toward the strong upper group, not the other way around. With any luck, W will get an opportunity to defend the weakness around M16 during the attack. |
