This is Arasan 5.3's score: material score = 114 white pawn score = -4 black pawn score = -3 outside pawn score = 3 king safety(w) proximity = 0 cover = -31 mlevel = 10 battery (b): score = -20 mate= 0 stack = 0 battery (b): score = -24 mate= 0 stack = 1 king safety(b) proximity = -65 cover = -72 mlevel = 10 net king safety score = 101 total score = 0.42 (The scores are based on 1 pawn = 64 units. "proximity" is a measure of closeness of enemy pieces, "cover" of the king's pawn cover, "mlevel" of the opponent's material level. "battery" measures danger from rooks/queens on an open file near the king). Arasan generally doesn't give monster scores for king safety/ danger. 101 (about +1.5 pawns) is a pretty high score here. King safety is very tricky. Here is a position my program had recently against zippy (GnuChess): r1bq1r1k/ppp3pB/2nb2Qp/3pp2N/3P4/2P2N2/PP3PPP/R4RK1 b - - 0 1 Arasan thinks White has a fine attack going, but in fact there is really nothing he can do (Crafty doesn't like this position for White because the bishop's position triggers its "trapped bishop" penalty - and it is in danger, but that's another issue). --Jon
