Happy birthday Judit Polgar! I'm a day late celebrating your 21st, but that chap who writes the Creativity column wrote so much yesterday that I felt I couldn't do you justice in the slim space left for chess.

Now that you're an old lady of 21, it's nearly six years since you became the youngest grandmaster ever - and that record has now been broken by both Peter Leko and Etienne Bacrot. Meanwhile, you have progressed to 13th place in the world rankings (or 12th if we exclude Gata Kamsky, who has had enough of chess for the time being). Not bad for a 21-year-old, but the really encouraging point is that there's no one younger than you in a higher place. Yet Kramnik and Topalov are only a year older than you, and they're already in second and fourth places. You've a lot of work to do in the next 12 months if you're to catch them up.

This year, you seem to have moved into a higher gear. In four tournaments - in Dos Hermanas, Linares, Madrid and Dortmund - you've shown that you can be a threat to the very best. It's the raw energy of your play that I find so exciting, as you showed in this game against Jeroen Piket in Linares. Your sacrifice of two pawns in the opening was bold, but what showed real class was the cool way in which you refused to win them back until the time was ripe. And the way you won a piece, then gave it back for a mating finish, was most impressive.

White: Jeroen Piket
