Can zugzwand be a weapon ?
Its extremely useful weapon in the endgames, though sometimes it can prove useful/piece winning strategy in the middlegames too... Here is more info on Zungwang for your reading pleasure:

A common method of putting your opponent into zugzwang is "triangulation". If you look up the term you should find a bunch of pawn vs pawn and queen vs rook examples to look over. In Bishop vs Knight endgames, the goal of the side with the bishop is often to put their opponent into zugzwang, taking advantage of the fact that a bishop can often lose a move (when operating along one, long diagonal) while the knight cannot--each time it hops it guards completely different squares.
Zugzwang (not sure if i wrote corecty) is a pozition in witch the plyer that makes te first move loses. So i thought : hey this might be a weapon, but i'm not quite shure how to get my player into zugzwang. Maybe you could give me an advice how do do it :), or show me how you did it . In this game we can see how Bobby Fischer, playing White used zugzwang to win.
