Catching up on the chess news in brief, here are three brevities from recent events. The first comes from a tournament in Budapest in October.

It was more than 30 years ago when Bent Larsen first demonstrated that Black can safely allow 15.Bb5+. His king is inconvenienced, but the strength of the knight on d5 is more than worth it. In this game, White's 18.Qh4 combined with 19.Nd2 add up to gross negligence. Once Black has been allowed to play g5 and Nf4, White's game falls apart. There is no answer to 22...Ne4, since 23.bxe4 loses to Ne2+, while 22.Qg4 is met by ...h5.

The next game, from the Russian Cup in St Petersburg, sees White improvising an extravagant idea - which works to perfection. Against Black's unusual hybrid of a Queen's Gambit Accepted and Grunfeld Defence, 6.b4 looks a rather clumsy way of preventing Black from striking in the centre with ...c5. After 9.Ba3!? and 10.b5, however, it was clear that White's plans were more aggressive.

If Black plays 10...dxe3, then either 11.Bxf8 or 11.fxe3!? Bxa1 12.Qxa1 leaves White well placed for a direct attack on the king. As the game went, Black tried to ensure that f7 was well enough defended, but was caught by 17.Bxf7+! White's final move is most elegant: the pinned queen cannot take the knight, and 18...Bxf6 19.Rxf8+ is fatal.

Back to Budapest for the final game, in which a classical pawn centre is brought to a state of total collapse by persistent nibbling from the edges. Black's devious opening play is more difficult to meet than it looks. White really cannot afford the time for 9.h3, as he soon discovered.

Since 11.0-0? would simply pin his own d-pawn and lose the pawn on e5, White could find nothing better than to give up his proud centre, but he was still unable to castle. Black soon found himself way ahead in development and White could only wait to be killed by an invasion of the black rooks. At the end 23.Bxe2 Qf2 is mate.
