Mobility Evaluation ?
Posted: Wed Oct 12, 2016 11:38 pm
Right now my Evaluation considers material , PST , passed & isolated pawns, and basic mobility (Mob Score=5*#Legal Moves)
1-Is counting completely safe mobility better than just counting moves to squares not occupied by my(king or pawns ) and not attacked by enemy's (king or pawns) , or is it not worth it "Generally"?
2-I'm using Adam's and Pawel's PST , could someone give good weights(count ,(mid , end)game) for mobility to go along with those ?
3-How much improvement should I expect by switching to whatever the best method is from the two mention above in #1 ?
*by the way why does stock Fish do this : for Bishops and rooks only ?

*by the way why does stock Fish do this :
Code: Select all
// Find attacked squares, including x-ray attacks for bishops and rooks
b = Pt == BISHOP ? attacks_bb<BISHOP>(s, pos.pieces() ^ pos.pieces(Us, QUEEN))
: Pt == ROOK ? attacks_bb< ROOK>(s, pos.pieces() ^ pos.pieces(Us, ROOK, QUEEN))
: pos.attacks_from<Pt>(s);
