King Safety is the part of latista's evaluation that I'm
most worried about. Sometimes it gives a really high score
when it shouldn't, and also the low scores when it's own
king is in deep trouble.
looking at the static evaluations of each position of the
game, In this game it seemed to do a decent job of properly
evaluating the attack. but maybe others have an opinion too.
Here Latista gave a score of 46 for the whites king attack
[d]r1bk1r2/ppp1nBb1/3q2Qp/8/3n4/2B5/PPP2PPP/RN2R1K1 w - - 0 25
The highest the evaluation ever came was in this position where
white's king attack reached 72 centipawns.
[d]r7/p2k4/1p2bq2/1N1p1r2/8/4Q3/PP1R1PPP/4R1K1 w - - 2 38
Thanks for giving it a try!
