Pre BQM 32
Here is the sequence of moves preceding BQM32. Someone seemed curious. --BlueWyvern
Play went upper right, lower left, lower right, upper left, followed by the establishment of the SmallChinese pattern on the top. At this point, white approached with one. I was considering extending up, but then I decided I'd prefer a more aggressive line of play, and played the wide high pincer with the aim of splitting up the left side up. Through 7 is joseki I believe, then I decided to tenuki with the splitting move at 8. When white played at 9, I thought the approach at 10 in combination with the splitting move would make up for white's local profit when he plays 'a'. DaveSigaty: A couple of points:
Somehow I have a feeling that your original idea of extending up was more in keeping with the Small Chinese choice at the top. Something like this 2 through 4 leaves B perfectly placed to make best use of the fighting capabilities of the Chinese formation. White is also developing quickly and smoothly but presumably feels that she is playing according to B's plan.
Actually finishing the bottom right looks absolutely necessary. Let's assume for the moment that W next chooses to take control of the left side with 4 and that B 5 and W 6 are then exchanged. B is very solid along the bottom. There remains a standard invasion point at 'a' but it only aims at diminishing B's territory. Meanwhile there is an offsetting invasion point for B at 'b'. Even if W adds a stone at 'c', the meaning of the invasion at 'a' does not change greatly. Contrast this with the actual game where W played at 3. This is much more than just a local territory grab. It undercuts the base of the entire B formation on the bottom half of the board. Especially after W becomes strong in the lower left, there is a real danger that W will divide the B stones in two (possibly even into three) groups and attack the whole bottom side on a large scale. unkx80: Just one comment.
Dave's point is exactly the one I had wanted to make, unfortunately his diagram is wrong. Black 3 here is way too big to ignore. Allowing white to play at 5 gives white at least 15 points of territory on the bottom right, destroys any possible black territory at the bottom, and causes the three marked stones to become practically useless. The thickness of the white group cannot be underestimated as well.
