I just finished a correspondance game against a 1k player. Needless to say, I was overwhelmed, and I’m not so greedy with other people’s time that I’ll demand a full review of a stronger player.
What I do want to know about is a sacrifice play I made just before I resigned:
The sequence began when white chose to connect his stones at H17. Move 128. After this move, I saw potential to use the shortage of liberties for the white group to turn the seki in the top left into a living corner by sacrificing 11 stones. In the game, this lead to my defeat, since in addition to sacrificing those stones, I built white up against my other weak group in the other corner, and I reasoned it would be impossible to continue play, hence my resignation.
Here are my three questions about the exchange:
1.) first off, was I even right about the top left corner becoming seki? Was there some way for black or white to kill the other outright without the sequence? I thought my opponent had played a bad move in the joseki for that corner, but he followed it up with a play I’d never seen before, so it became a confusing mess for me.
2.) Did white make any mistakes responding to black after move 128 that made the exchange possible? Basically, did I misread and my opponent blunder? Or was white’s play optimal up to that point.
3.) I know that in this game the exchange wound up strongly favoring white, but assuming an empty board, was the sacrifice of the 11 stones for the corner even? Or in that case would it still favor one player over the other?
thanks for listening to my problems. XD I’m open to any discussion or criticism about any part of the game, but I don’t want to trouble anyone.
