Post subject:  A game against the reliable opponent.

Hello there, everyone. This is my first game in a long time against COSUMI, the online Go-playing engine. And this time I played even. (I just played this and it's late at night where I am, so the sluggish play by Black seen in the game is due to physical fatigue as well as to the need for more playing.) Much obliged in advance for your comments.

I think Chineses aim at developing on the bottom of the board, so after white plays E3 high Chinese might not be the best fuseki choice. Enclosing, or approaching inside white's 5-3 might be moves.

This 11 is my intuition, because now white 'a' black 'b' looks good for black to me. White 'x' black 'y' leaves the threat of black 'q' later.

The game sequence seems unsatisfactory because:

Hi

You are free to use physical fatigue as an excuse but it's preferable to play in the best circumstances and then learn something from your best possible game. Otherwise you may continue soothing yourself with "I'm really better than this" which is not going to help you in the long run.

Your opening was better. Half way the game could still go either way. The focal point is :w98: where White builds a major lead. Black's only chance is to attack the bottom. The variations there are not easy to find but fighting back is stil better than harnassing the loss. Perhaps this requires some positional judgment first.

Cheers!
