I have had this experience many times: 1. You see a move that sucks. 2. You identify the problem and engineer a solution. 3. The solution indeed works - it cures the problem. 4. The program plays worse than it did before.
By the way, you are being modest, Antigo is not bad on 9x9. It's true there is a pack of programs that are way out front, but they are mostly different version of just 3 or 4 programs. Your program would be the top program if it was on the server 2 years ago. Do you remember when CGOS started? It was an impressive feat to break 1800 back then. - Don [EMAIL PROTECTED] wrote: > My engine, Antigo, is not one of the strongest and only plays 9x9 > games.
