Nigel Short self-destructed in the opening game of his world championship quarter-final against Nigel Short. Thanks to some clever play in the opening (his 6...Nf6! is a big improvement on the natural cxd4) he gained an early initiative and turned this into a clear space advantage on the Q-side.

When Black had established a pawn chain at a5, b4 and c3, and had his bishop firmly cemented on d4, Adams could only wait for his opponent to launch an attack with f5. Both players manoeuvred their pieces to be ready for that advance, but when it happened, it looked as though Black was well on top.

Short must have planned well in advance to meet 31.Nc4 by sacrificing the exchange, but it did not turn out as well as he had hoped. After 35.f4, the position became very loose. Shirt won the pawn on c2, but it was Adams's e-pawn that won the game in Short's time-trouble.
