I am working on a plan to possibly be able to run 2 boardsizes on Dave Dyers boardspace site. If this plan works out, obviously 9x9 is very popular and we will keep it. The only questions is what should the other board size be. It is starting to appear than 19x19 is the second most popular

7x7 is actually not very interesting for computers. I did some tests with Lazarus, which is far weaker than many of the better programs and the games are one-sided, depending on the komi either white or black wins every game. If you made the komi 9.0 probably all the games would end in a draw.

I played on that temporary 7x7 server and I think the better programs came close at being almost unbeatable on 7x7 white and 9.5 komi especially if one uses the known opening library. So it might quickly get boring for most better programs. Although losses with white might reveal some

I did a ladder reader once. Basically it's an alpha beta search where you focus on one group only, and that group has limited liberties. If it's strictly ladder reading, you only consider attacks that reduce the liberty count of a specific string to 1 (atari moves in other words) and defenses

Okay, let me see if I can sum this all up. Let 2, capture, attacker stand for defending chain has 2 liberties, it will be captured if the ladder is played out, and it is the attacker's turn. Use the following rules to suggest moves: 1, capture, defender = defender plays ladder breaker,
