Zugzwang
2/10/2010 – Although there are of course beautiful examples of zugzwang in the
middlegame, it is much more a motif from endgames, many of which could
not be won without zugzwang. Even when there is a clear superiority in
material, as for example in the duel between a rook and a bishop, it is often
only possible to make progress by employing zugzwang. Here is a
typical example. After 68.Kb5 Black could, with the correct
continuation, have retained his chances of a draw. What that was and
the instructive winning method used by White after 68...Bc5? are
things you can find out from Karsten Müller's analysis in ChessBase Magazine Online.
