I just finished watching the NHK Tournament 4th round match between Iyama and Murakawa.
The game is here... http://www.go4go.net/go/games/sgfview/46034
I've been watching Igo for a few years on TV and play against my phone, so I'm a pretty poor player I'm sure. But the outcome of several NHK matches have had me confused and this one more than most. It seemed to me that Murakawa outplayed Iyama the whole match, winning the bottom right corner and the top left, with some chance to diminish black control in the others yet to be played out... the central battle hinged upon Murakawa being able to keep his chain on the left alive, which I think he managed to do. So why did he resign? Having won so much, was he really in such a bad position? If he continued to play, what do you foresee the score being?
Before I go around claiming nefarious play too much, I'd really appreciate other people's opinions on the game. Thanks in advance!
edit - Using the trial play function, I think if white plays at either D6 or H6 he gets a second eye, and I can't see how black can stop that...?
Or the other way around with the last two moves. ??
edit2 - Ah that's a bit flawed, a much better play for white is..
White then has three eyes to choose from and ignores the one that black attacks.
