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

A quote from Richard RETI's Masters of the Chessboard(p 395):
"In general, it can be established that there are two defenses against 1. e4, which make it absolutely impossible for the first player to take any initiative, and which give Black such an even game, without any difficulties at all, that it has now become useless in practice, since these defenses are generally known. They are the Caro-Kann Defense and the variation of the French Game: 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 dxe4."
Glad that's settled! :-)
