At this point of the game white has to admit that the left side groups are dead and think in terms of how can one use them yet to one's advantage.
White 1 threatens to cut off a large black's group. Black 2 prevents the cut but it was a mistake as accurate reading shows. Black could play at 3.
Black 3 threatens to connect on the first line, if white connects with 4 then black 5 and seven put white into a damezumari situation: a groups is under atari, but connection at 'a' does not increase the number of liberties, so black does not have to fight a ko to connect. White 3 in the game, encouraged by a submission of the opponent, pushes further. Black 4. Black continues to play submissively, but if black plays at 5 now he will have to fight a ko to save his stones. White 5. Captures 3 stones. The value of this move is a little bit more than 3 points. But white is also scared a little about the status of the group at the bottom etc. So white clarifies the situation at the bottom and in the center. It is important to note that players of IGS 5k level in a fast game (10 minutes for 25 moves) cannot as a rule count the score. They have an impression only. In this case white feels that the game is close at the moment, if he is behind then only just and there is a hope for a win. Black 6. This is a very large point. Is it the largest? It needs calcualtions. White 7. A mistake. White does not agree that the previous black's move was the largest. He thinks that saving 2 white stones and capturing 2 black stone is a bigger move. But at least white had to use the psicology of the opponent.
If black considers playing in this area the largest move on the board then he would answer white's 2 and and in gote. White will be able to save his two stones while the situation at the top would be settled. Black 8. Natural continuation. Black considers this region the most important. White 9. White insists that there is more in the center yet. He is wrong, though a later mistake by black helped him. If playing here white would be better with 'a'. Black 10. Black continues to insist. Actually, this is most often a correct approach to yose. Don't reply, don't give your opponent the luxury of sente moves. Next PGB201 This is a copy of the living page "PGB211" at Sensei's Library.
