Game 4:  Polgar vs. Morozevich

0.
@Q0
[Introduction: It's round four at the Wijk aan Zee 2000 tournament, a category 16 event, which means it's very strong. The World Champion, G. Kasparov, is present (he eventually won the tournament), as well as his last challenger, V. Anand. Also present is his future challenger, V. Kramnik. 

Your partner for game number four is the young Russian grandmaster, Alexander Morozevich. Your opponent is Judit Polgar, the top woman player of all time. Judit has White, and you (Alexander) have Black.  

Your main task is to get out of the opening alive and in one piece. Judit is like a killer shark, one of the most vicious attacking players on the planet today. So you'll have to play the opening soundly, and yet somehow manage to muddy the strategic waters, so Judit can't find her attacking foothold. Fortunately, Morozevich is good at that sort of thing. To see how he does it, and how he also wins a special prize for beautiful play, just follow along with the game. The opening is the Burn Variation of the French Defense.]

[Conclusion: The selection of the steady Burn Variation in the French (4...dxe4) is intended to throw a damper on White's attacking ambitions. But the follow-up capture, 6...gxf6, instead of the more solid 6...Bxf6, shows that Morozevich has some long-range plans of his own, namely to use the semi-open g-file. 

The first step for Black is to establish a central presence. Morozevich does this by working his bishop to d5, supporting it with his backward c-pawn, and insuring that the bishop cannot be driven out by a White c4-pawn. That all takes place starting at move seven and running through move fifteen.  

Step two is to take away White's attacking options: 16...a5 denies White use of the a5 square; 17...Re8 safeguards the e7-bishop from sacrificial tricks on d5; 19...Qb8 and 19...Qb4 reduce White to passivity on the queenside. And all the while the d7-Knight stands guard over the possible entry points c5 and e5. 

Only after the preliminary defensive work is done can Morozevich think about pursuing his own chances. With 21...Bf6 he puts the d-pawn under fire. Then rooks are doubled on the g-file (moves 22-26), and finally the battering of g3 begins in earnest, 27...f4 followed up by 29...h5 and 32...h4. The queen crossing to the kingside, 34...Qe4!, completes the picture. And at the very end it is Polgar's king that cannot avoid mate.]
