Zugzwang in the Middle Game by GM Nadezhda Kosintseva
In this lecture I am going to talk about middlegame Zugzwang. The term Zugzwang refers to a situation where one of the players has to move whereas he would prefer to yield the right to move to his opponent. Every move he makes worsens his positions or leads to immediate loss. You see it mainly in the endgame, but it can also occur in the middle game with plenty of pieces on the board and many continuations at the player's disposal. I will provide two examples of this rare form of Zugzwang. The first one is one of the craziest studies I have ever seen on the Zugzwang theme. Non-obvious decisions for both sides, a lot of tactics and traps that are easy to fall into. The second example is about a strategic Zugzwang where every move leads to a positional disaster for the defender in spite of the fact that he has no visible weaknesses.
