It's not only psq in those 11 parameters. This is what they represent:Rémi Coulom wrote:It seems your psq has only 7 different values. I don't understand how you can make it 11 parameters. What are the meanings of P1-P11?
p1 - ampli for king psq, non ending
p2 - bias for king psg, non ending
p3 - ampli for king psq, ending
p4 - bias for king psq, ending
p5 - ampli for king attack table (king attack evaluation)
p6 - bias for king attack table
p7 - Missing pawn cover constant
p8 - Missing bishop finachetto constant
p9 - Pawn storm multiplier
p10 - Moved f-pawn before castle penalty
p11 - Moved pawn in front of castled king penalty multiplier
So p1+p2, p3+p4 and p5+p6 adjust three different piece square tables. The others are more normal values (and are looking fairly reasonable).
