Until maximum depth Crafty keeps Be5. I was talking about the case when crafty plays Be7 without all the game and not about the case when crafty plays Be5. I meant that crafty does not use enough time to analyze Be5 to see that it is a draw if it has not the game. In this case when crafty is at depth that it can see that Be5 is a draw it is not relevant because it knows at the same point that Be7 is winning. Uri
