I was wondering about the way a typical evaluation function works. Is it
not more productive to evaluate the position in terms of sides of the board and
is this done? I ask this because a typical anti-computer chess strategy is to
build up an attack against the castled kingside. The computer typically doesn't
see an early kingside knight sacrifice as a major threat. (see Ed Nemeth's 17
move mate against shredder 5 ) Ideally as I see it, a computer has the potential
to calculate scores for piece positions on the 2 sides of the board and to use
these scores constructively as the game progresses (with an attack strategy on
one side in mind). So it should be the computer making aggressive deadly
sacrifices early to create direct attacks on the casled king.
You should have (ideally) the queenside evaluation and the kingside evaluation
for all pieces on those sides of the board. In Capablanca's book "chess
fundamentals" this is the way he approaches chess, and we all know that he
played extremely simple astonishing moves. He also stated that in Grandmaster
play one common way to win was to divert the opponents pieces to one side of the
board, then quickly shift the attack to the other side. I rarely if ever see
computers employing long term strategies such as these unless the position calls
for it.
