Crafty won't want to do >this. > yeh, This is roughly what crafty got after I forced a few of my own moves, but Kh1,Nh2 counters most of that. Its good to see it did try and crack the player. At blitz time controls, my engine has no answer to d1d2,d2d1. I am thinking of putting some specific code into getting more agressive if a player tries this. I have some code to detect blockaded positions, whilst this isnt technically a blockade, but if you take into account previous moves, maybe I can persuade chompster to view this type of play as a blockade, and try more forceful moves.
