Re: Evaluation without material count

Hmm appears to be a lucky game. For in next game I see it gives away too many pieces. Maybe I can change its only mobility term to fix that.
Not very promising.

Evaluation without material count

I wondered if it would be possible to play a reasonable game without counting material. In the game below evaluation only computes a sloppy mobility term for each piece type and no other terms added, Unfortunately I had to add a material term for the pawns. Otherwise it would give away too many pawn...

For some reason my Stockfish Dev crashed when it got to 98 plies deep - showing +4.34

Lc0 does better showing +0.8
Does that mean 80% winning chances or 80 centipawn ?

Misevaluation.

I saw this funny position on my chess club recently. Played in a real game.

Looks like Stockfish can't see it is a draw.
