Of course it's often bad. Everybody knows that already. That's why there's no program on Earth that has a knight piece/square table where a8 is higher than e5. What you are proposing is to decrease that value to account for major, short-term tactical issues that may or may not exist. I don't think this is a good idea, but you don't have to take my word for it. Download Crafty and try it out. >I also said that we should not use pawns to evaluate how much a guess is wrong >and there is no big difference if the guess is wrong by 5 pawns or by 6 pawns. I have no idea what you're talking about. >Note that simple calculation say that you may need 100000 games to check if a >small change is really an improvement of 1 elo and analyzing 100000 positions >when every position analyzed for few minutes is clearly faster than playing >100000 games. But analyzing the positions will not necessarily tell you if you gained or lost an ELO point, that's the problem. -Tom
