Sacrificing the queen
From our UK edition
One of the most eye-catching games from the recently concluded Fide Grand Swiss in Riga saw an early sacrifice of queen for knight, bishop and pawn. This exotic balance of material usually favours the queen, based on the rule of thumb that pawn = 1, knight = 3, bishop = 3, rook = 5, queen = 9. But when the minor pieces coordinate well, particularly with rooks alongside, they can be more than a match for the queen. A queen’s greatest strength is her ability to attack, and perhaps fork, any pieces that are not nailed down. So when you jettison your queen for a miscellany of pieces, they had better resemble a florentine more than a fruit salad. It helps when the minor pieces have a clear target of their own. That is the situation that occurred after 14 Be2 (see diagram 1).
