The magnificent run of Magnus Carlsen at the prestigious Morelia-Linares tournament made headlines last week. The 16-year-old Norwegian grandmaster was outplaying some of the world's best players and after six rounds led the formidable field with four points. He edged India's Vishy Anand and Armenia's Levon Aronian by half a point before yesterday's last round of the first half. The double-round robin event moves from Morelia, Mexico, to Linares, Spain, this week.

Meantime in Moscow, the 21-year-old Russian champion Evgeny Alekseev triumphed over nearly 80 grandmasters and won the Aeroflot Open on Thursday. He scored seven points in nine games, and his victory earned him the right to participate in the elite tournament in Dortmund, Germany, this summer. The best American finisher was Jaan Ehlvest with four points.

Rook-Pawn StormingTwo games from the Aeroflot Open had a common theme: using the rook-pawn as a battering ram to break down the gates of black's kingdom. Alekseev was able to push his h-pawn all the way against his countryman Stanislav Novikov, the winner of the last year's Czech Open.

Alekseev-Novikov

1.e4 g6 2.d4 Bg7 3.Nc3 c6 4.h3 d5(The hybrid of the Caro-Kann and the Modern defense is the lazy player's opening.) 5.Nf3 Nf6?! 6.e5 Ne4 7.Nxe4 dxe4 8.Ng5 c5 9.Bc4! 0-0 10.c3 cxd4 11.cxd4 Nc6(Protecting the pawn on e4 with 11...b5 12.Bb3 Bb7 leads to a strong attack for white after 13.h4!, for example 13...h6 14.Nxf7 Rxf7 15.Bxf7+ Kxf7 16.h5 g5 17.Bxg5! hxg5 18.h6 Bh8 19.Qh5+ Ke6 20.Qh3+ wins; or 13...Bd5 14.h5 h6 15.hxg6 hxg5 16.Bxg5 fxg6 17.Bxe7! with white's advantage.) 12.Be3 b5(Sensing the danger on the kingside, some players sacrifice a pawn with 12...Na5 13.Bb3 Nxb3 14.Qxb3 b6 15.Nxe4, aiming for the central blockade 15...Be6 16.Qa3 f5 with a playable game. That strategy is black's best bet.) 13.Bb3 Bb7(With the intention to meet 14.Nxe4? with 14...Nxe5!)

14.h4!(Marching the rook-pawn creates a raging attack against the black king.) 14...Qa5+(It is too late to go after white's light bishop with 14...Na5, since after 15.h5!

Rh5 21.Nd6+ Bd5 22.Nxe4 and white wins.) 20.Bxf7+ Kf8(After 20...Kh8 21.h5 b4 22.h6 Bf6 23.Rh5 e5 24.Qb3 wins.) 21.h5 b4 22.h6 Ba6+ 23.Kg2 Bf6 24.h7 Kg7 25.d5(Alekseev misses the simple 25.Bh6+ Kh8 26.Bg8, threatening to promote the h-pawn after 27.g7+.) 25...Qc7 26.h8Q+(Touchdown! Playing for the gallery, white goes for a forced winning sequence, including a queen sacrifice. Otherwise 26.Qa4, with a double threat 27.h8Q+ and 27.Qxa6, is sufficient to win.) 26...Rxh8 27.Rxh8 Kxh8 28.Qh1+ Nh4+ 29.Qxh4+!

Uzbekistan's Timur Gareev used his h-pawn to stage a vicious attack against Sweden's Emanuel Berg in the Exchange variation of the Queen's gambit. Gareev found a marvelous way to take down black's kingside pawn barrier.
