Hi all,
I just watched an interesting game on ICC between my engine (monsoon) and
Steve's (Chesterx). In the game monsoon is ahead by a few pawns but ends up
losing because its king is out of position and chester is able to queen a pawn
with the help of its knight. Here's a position:
[D]2n3k1/p4p2/2N5/P5pp/1P6/5K2/8/8 b - - 0 34
Monsoon loves black in this position even after a 13 ply search -- my pawn
majority code is boosting the score and it thinks between the knight and the
pawn it will be able to contain the white pawns on the queenside. I'm only a
chess amateur but it looked to me like black was in pretty good shape too.
Well just a few moves later the picture has changed!
[D]2n5/N4pk1/8/PP4p1/7p/5K2/8/8 b - - 0 36
By now monsoon realizes it's in trouble. My question is this: how deep does
your engine need to search to realize the danger in position 1? Is there any
static eval rule that might help to understand these positions bettwe? Did
monsoon blunder the endgame? If so, where?
I think my aggressive pawn push extensions are hurting me in the endgame.
