Subject: Look at this !!(??) move by Crafty 18.14!

[D]8/B5pp/4k3/P7/6n1/8/P6P/7K b - - 0 41

Crafty as black played Nxh2!!(??). Yes the game ended draw so the move is
probably correct, but I doubt, that Crafty's evaluation really understand this.
E.g. if white plays a6 then black has no way to a8 square...

Crafty 18.14 is clever endgame player, but still I am disappointed, when version
17.14 solves 4 positions more in my 40 position endgame test and also 17.14
is on average about 30% faster in all postions!
