Lev Aronian , born in Armenia in 1982, is no stranger to chess fans around the world. A former world youth and junior champion, Lev is currently Armenia’s number one player and is rated (September 2010) number 4 in the world. His style can most easily be described as pragmatic (like former world champion Tigran Petrosian) and technically refined. Lev has won many international tournaments and some fans view him as a future world champion contender.
White’s idea is tied to potential threats of mate on d8 or e7 (the reason behind Bg5) and to encourage Black to accept a slightly inferior endgame after the natural 13… Qc4 14. Rfd1 Qxd4 15. Rxd4 Bxf3 16. Rxb4 Bc6 17. Na5 etc. Instead, Black decides upon a speculative but attractive attack against the White King
Black is infact virtually obliged to sacrifice a piece here since after 15… Bh5 White would build up serious threats after 16. Rac1 Qe6 17. Nc5! etc.
Black has some very real compensation for the piece, especially since for the moment the White pieces are somewhat uncoordinated and awkwardly posted.. Lev must now decide whether to allow Black a perpetual check (by playing his King into the corner and allowing a repetition of position by …Qf3ch) or risk trekking his King over to the Queen side. Lev decides on the latter idea…
Lev went on and won the game with a beautiful counterattack. Play it over on the pgn viewer below
