=**Alekseev takes Aeroflot Open**=


 * Problem:** Black to play and mate in 3.

21 year old GM Evgeny Alekseev, winner of the Super Final of the Russian national championship in December, has taken another step toward the world elite by winning the strongest open tournament in the international calendar. The Aeroflot Open regularly attracts an enormous turnout of strong grandmasters and this year's 88 player A1 group boasted 75. Players in the top 20 tend to avoid the cut-throat competition in these kind of events, leaving the next tier to contest the US$30,000 first prize. By winning outright on an unbeaten score of 7/9, Alekseev also earns an invitation to the prestigious Dortmund supertournament later in the year. It is in that event, going head-to-head against the best, that Alekseev can hope to break into the elite group of players.

Today's game is from the 7th round the Aeroflot Open and features Alekseev with White against the then tournament leader, GM Stanislav Novikov. To win this kind of event, one has to take risks to generate many wins against tough opposition. Here White launches an all-out assault on the black king, finally breaking through down the h-file. media type="custom" key="26933100" By transposition the fianchetto variation of the solid Caro-Kann defence. Instead of the safe 6 Bd3, White's next move provokes a sharp contest for the centre – giving White kingside attacking chances at the cost of the right to castle. Black must strike at the White centre or be overrun. It is possible that delaying this move so as to keep the a8-h1 diagonal open for the light squared bishop and retain the possibility of a future ... e3!? - sacrificing the e-pawn to extend its influence - holds better chances. Not 13 Bxb5?? Qa5+ winning the bishop. Here 13 ... Qa5+ would have prevented the possibility of 14 0-0, but White wants his rook on h1 to support the attack anyway. White throws everything at the attack, since his centre cannot be maintained. Black must lose a little material as a result of White's threats, but hopes to create active counterplay in the centre and against the exposed white king. The exchange must go, since if 19... Rb8, 20 h5 & 21 h6 is crushing. In this kind of position there are so many possibilities that even top grandmasters miss combinations: Here 25 Bh6+! Kh8 26 Bg8! sets up the threat 27 g7+ Bxg7 28 Bxg7+ Kxg7 29 h8=Q+ etc which Black can only stop by giving up his queen with 26...Qg5+. Missing the spectacular coup-de-grace that White's last move prepared. 25... Kh8 would have prolonged the defence. After 34 ... Kxf7 35 g8=Q+ Kxg8 36 Rxc7 White has an easy endgame win.
