The Trebuchet

In an all-parent encounter last week, the players stumbled upon this position, known as the Trebuchet. A trebuchet is a big wooden catapult, and its connection with this position is not known, except that it may catapult a player from joy to despair...

Normally, it's an advantage for it to be your turn so you can get on with your plan, but in this position, whoever has to move next, loses! Can you see how?

The situation of an unhappy forced move is called Zugzwang; it's not ever so common but more unusual is this situation where BOTH sides are in Zugzwang.

Chess Quotes

"It was night. I went home and put my old house clothes on and set the chessmen out and mixed a drink and played over another Capablanca. It went fifty-nine moves. Beautiful, cold, remorseless chess, almost creepy in its silent implacability.

When it was done I listened at the open window for a while and smelled the night. Then I carried my glass out to the sink sipping it and looking at my face in the mirror.

'You and Capablanca,' I said."

— Raymond CHANDLER, The High Window, final sentences.
