Every now and then I browse through some of the recent training and rating games on katagotraining.org. Quite often I stumble upon some particularly pretty move and think to myself “I should make a review of this game!”… but reviewing a whole game is hard work.
So in this thread I’ll go the lazier route of just posting screenshots of moves I like. I hope this is enjoyable to some people, and perhaps others would like to share their own highlights as well
To start us off, below are three beautiful moves from a rating game between two 60b networks.
Amibitious cap to keep the white stones working together:
A lot of younger players these days have a very different view of the middle and the cosmic moyo.
But current top human pros (especially Korean and Chinese players) seems to take the lesson from AI to another extreme with increasing fragmented territories and more intense fight in mid-game. I suspect we need a generation of new players to finally throw out the baggage and the fixation for local fight. And we can revisit the idea of “reasonable moyo” and what “potential” really means, instead of just a vague theory about influence and thickness.
The bots print out their winrates in the chat, and both bots and the Ogs review seem to agree that the JBX katago was winning all game up to move 154.
Then strongbot plays the turn to threaten to capture the corner stones, which it seems the Ogs review didn’t consider, and presumably neither did JBX bot. It’s a big five point swing in the estimate and now suddenly Black, strongbot is in a winning position.
I think something like O8 instead of G15 would also be ok, but allowing black to atari at G15 is painful, so in the game white decided it’s better to just let black save R6. The sequence that follows on the lower right is locally a little good for black, but since black already paid the cost of making the bad H16-G15 exchange it’s an even game.
