After a lot of trial and error I arrived at the following weight table, on which it was not easy to improve in a way that would be obvious in 1 million games:
Code: Select all
attacker victim
- P N B R Q
P 1 400 250 250 250 400
N 1 75 150 75 75 75
B 1 60 60 100 60 100
R 1 40 40 40 60 100
Q 1 6 25 80 80 100
K 1 50 50 50 50 50
Could you post a few sample games with the final weight table? Interested to see some games

Although I normally don't save the games, the game generator fortunately also is a normal WB engine, so I can play it against itself under WinBoard and let the latter save the games as PGN. (The first attempt atthis led to spurious draw claims, as it did not update the position key on moves that it did not make itself, but that is now fixed.) Here are a few typical games
