I will give a different position when I believe that white is winning and it is impossible for program to see a draw by search. [D]1rb5/rp1p1ppp/pPpP4/P1P5/7k/5K2/3B1PPP/8 w - - 0 1 Can program with white avoid bxa7 that let black free the pieces? I can give position when program has no chance to see a draw by fortress position but 1.5-.5 is not enough for me and I try to give a position when every 1600 player can win the programs 2:0 even at correspondence time control.
