The problem is that all the positions here evaluate the same. None of them are obviously drawn or obviously won, so the only way the search can find a draw score is to find a repetition or 50 moves in the PV. White cannot be forced to make a repetition, so the only hope is to search this to 100 ply, but this takes too much time. Amir
