Very imaginative! Black has not castled, yet the capture of this pawn will speed up an initiative on the kingside.

Too slow. 20...h5!? 21.g6 f5.

Oops.

On 22...Rxh6 23.Qg8+ Bf8 24.Nf5 wins back the rook, preserving a much better position.

White should have had a winning advantage, but his much higher-rated opponent eventually escaped with a draw.

A brave decision from Ukraine's star.

Ukraine's former rising star goes wrong. Now the a5 -knight will soon have a more active future.

A double exchange sacrifice!
