Long time no write! The past week has been a bit busy for me, hence the small amount of posts here. Right now I’m in Tampere, ready to play in the Rabbity six tournament which begins tomorrow. I decided to share with you readers what I reviewed with Jeff concerning the game I played with smartrobot on KGS last week. I had black in the game.
Generally, I thought the game was very good, the number of noticeable mistakes being rather small for both. Apart from this game, I’ve played several other games as a preparing for the tournament – also in the European Team Championship tournament on IGS. My general feeling is that I’m pretty much in top shape now!
The opening game here is something I’ve been experimenting on, especially the black 11 stone. A common joseki move would be something like A, but to me that doesn’t seem the least bit interesting. 11 is rather more fast-paced.
Since black didn’t want to play the normal extension of A in Figure 1, it’s logical white plays around there himself. The sequence from 13 to 19 then was actually premeditated by me. If, after black 19, white cuts with A, the sequence from B to D follows, and the two white stones on the lower side are getting pretty lonely. That’s why white plays 20 instead. If, instead of 17 and 19, black simply answers the white peep of 16 straight away at A, a white peep at 19 would be annoying, as it leaves black with bad shape. Black 21 and 23 are to get black to the centre of the board, and also to prevent white A.
White, then goes for the black lower left corner with 24. I decided to play 25, since after white 26 black can still choose between the cuts at A and B, possibly combined with the black peep of C. First, however, black asks what is to happen to the left side with black 27.
White further decided to siege the black corner with 28, to which black responded with 29 and 31. An annoyment for black is the white peep at 32, which will be either connected to the white stones above, or the white stones on the lower side. Both black 31 and 33 could be better placed:
With black 33 here, the white stones would stay nicely connected – and white is still eyeless. Like this, a lot more of fighting would ensue. The situation here looks a lot brighter for black than in the game!
Seeing as I had lost my position on the left side, I determined the last chance to turn this game is building a centre. The moves from 63 to 69 then are reasonable. White 70 is timely to prevent the forming of too big a black centre.
I determined that simply enclosing the centre, letting white have the right side, would not be enough. Furthermore, there was the potential of black 73, 75 and 77 to use, still – this is something that was created back in figure 2, with move 17. White taking the upper right corner with 82 is then timely, again. Black plays the double hane of 87 to get the turn to play black 95 in the centre.
White, then, proceeds to shrink the centre with 96 et cetera. 99 here is not quite good enough, because it leaves aji to be used with white 100. This was pretty much the last nail in black’s coffin. Instead-
Black 99 would make a significantly bigger centre. The space down from 99 is extremely small, anyway, so black shouldn’t use too much effort to protect it. Like this, the game is likely still playable for black.
In the end, black lost a lot of the centre moyo, and lost the game by 10 points. In case you’re interested, here‘s the whole SGF!
