What i do not like is when the other player sets up a pawn defense. These are tough to break through and the main peices protect the weak part of the defense. You usually have to sacrfice something to get a small opening which can be a great lose. One of the few ways of stopping the other player from doing it is to attack before they set up the defense.
That's very true, but that's the reason they set up pawn defenses. Sometimes in those cases I've had to sacrifice a bishop for a pawn which really got me in trouble.
