Pawns are the soul of chess. I guess knowing if a pawn push is good or not is tough for even the strongest GM's. A pawn push can easily backfire if it cannot be supported. Rybka is especially good at that, but it takes it one dimension further. It actually uses the pawn push to create tangible weaknesess against the opponent. I think Rybka has an algorithim that specifically searches deep into pawn pushes, and this is an extremely powerful tool. GM's probably are not affected as much as engines since they can "feel" the danger. Engines however, sometimes seem totally oblivious until it is too late.
