Etienne Bacrot, who is bidding to become the youngest-ever grandmaster, came down to earth in the fourth round of the tournament in Enghien, near Paris, when he was beaten by the Latvian Igor Rausis in only 17 moves. Bacrot (aged 14 years and one month) began the event needing six points from nine games to complete the qualification for his grandmaster title. When he won his first three games, including a victory over the former world title challenger Viktor Korchnoi, it looked as though the task would be a formality, but his fourth-round loss means he still has work to do.

White's over-ambitious opening play was met in fine style with a queen sacrifice. With rook, bishop, pawn and a violent attack for his queen, it cannot have been too difficult a decision for Rausis to take. His 16...Nc5! was a pretty way to finish things off: after 17.exf6 Be4! any move of the queen is met by Nb3+. At the end with ...Rac8 and Be4 coming, White cannot survive for long.

While we are on the subject of 17-move wins with Black, here's another one from the ICI Katalpo quick-play tournament in Middlesbrough. The loser is a grandmaster and the reigning British champion. Here, however, he falls into a trap in one of his opponent's pet opening lines.
