By far, the Najdorf is one of the most fierce defenses available to Black, catering to some of the sharpest lines ever to arise within the game of chess. It is a defense that allows Black to counter quickly and fight for a win.
Unlike the French and Caro-Kaan defenses, the Najdorf is an opening that rarely eludes to drawish play. However, there are lines that White can play to force a draw in the Najdorf quickly, as demonstrated by the newly minted 2009 US Champion Nakamura; but both sides must play accurately or suffer immediate reprisal from their opponent.
