I had meant to reply to this post yesterday since the other game
of the two had Crafty playing Bxh7 though this time after Fritz had
played 13....c4 not Bc6 and Crafty lost.

Yes but it's only 5/0. I am not certain it even plays Nf6+ for the right
reason. Its score reflects it does but in analysis mode it takes much longer
than 5 secs to see this move as a large +.

I had never noticed that before, clearly it is autoplayer lag but something
I will have to watch for.


Thanks.
