Today's game starts with 15 moves of theory in a sharp line of the Sicilian before Black plays a new idea, improving the activity of his queen and offering a pawn sacrifice. White, probably unwisely, accepts the offer after which Black seizes the initiative and pushes his advantage home in a devastating attack, enhanced by an imaginative and original way of developing his queen's rook.

An everyday tale of chessplaying folk, you might think, but the remarkable thing about this game is that it was played in the English Under-14 Closed Championships held last week at Yateley Manor School, Hampshire. The event was restricted to players in the official British Chess Federation Junior Squad and enabled coaching to take place in a competitive atmosphere.

Black's 15...Qc5 is an interesting idea to increase his black-square influence, but White should not have been tempted by 17.Bxe5 and 18.Nxg5. Instead 17.Bf2 looks more to the point, fighting for control of the black squares instead of conceding them for the sake of a mere pawn.

Black's 22...Ra7! was a very important move, without which he would find it extremely difficult to develop his Q-side.

White's 24.Ng5 was a huge misjudgement. Either 24.Rhe1 (intending a quick Qe3) or 24.a3 (delaying ...b4) would have been much better. As played, the knight sortie not only lost time, but compunded the error with 25.Ne2? (25.Nb1 is now the only chance). When 26...Bb5 came, White had to move his queen while maintaining the defence of the knight on e2, but then came 27...Qc4 attacking both e2 and a2. With the loss of the a-pawn, White's game collapsed. Not bad for a couple of 13-year-olds.
