But suppose it can advance but it never ever can become pawn-defended? Wouldn't that be a nice attack-object too? How essential is it that the pawn cannot move? I am about to try that idea. - - - - - - - - - - - B - - - - - - - W - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - W - - - - - - - - - - - The e-pawn is sort of dead. What's your opinion about this? Of course there are exceptions, white can sack it's e-pawn at e6 to get a freepawn, if it gets far enough. But the fact remains that the e-pawn is not ever pawn-defendable and therefore weak. >Ignore backward and catch the weak pawns instead, as that will include >backward and a large group of other types of weak pawns that are not >backward. I already do that in Tao, but I am not satisfied about it's evaluation of pawnstructures at the moment. Crafty does a better job here. Best regards, Bas.
