The Najdorf Variation of the Sicilian Defence is one of the most complex and respected of all chess openings. It is one of Black's most popular responses to 1.e4. The opening is named after the Argentinian Grandmaster Miguel Najdorf, who was born in Poland 1910. This image is originally from xboard. ... This image is originally from xboard. ...

Black's fifth move, ...a6, aims to deny White the b5 square for his knights and light-colored bishop while maintaining maximum flexibility against White's attack. The knight (Old English: cniht = boy, lad or servant) (or, colloquially, horse) is a piece in the game of chess, representing a knight (armoured soldier) and often depicted as a horses head. ...

Blacks plan is usually to start a minority pawn attack on the queenside and put pressure on whites e4 pawn. Often this can be done through playing b5 Bb7 and putting a knight on c5. White also has to look out for exchange sacrifices by black on c3 where he usually has a knight posted guarding the important e4 pawn. This exchange sacrifice is a reaccuring theme in the sicilian defense. In chess an exchange sacrifice occurs when one player gives up a rook a minor piece (knight or bishop). ...

The oldest, sharpest response by White is an immediate 6. Bg5, generally countered by e6, followed by 7. f4, hoping to exploit the pin on the knight. The simplest response by Black is 7...Be7, leading to quick castling by both sides. However, Black can also play 7...Qb6!?, leading to the extremely complicated Poisoned Pawn variation (8. Qd2 Qxb2 9. Rb1 (or 9.Nb3) Qa3 (9. - Nc6 against white's 9. Nb3 is also a popular line)). Black is up a pawn but somewhat underdeveloped: however, his pieces can quickly become mobile and his position is not easy for White to break.

Because of the success of various players with these variations (notably Bobby Fischer and Garry Kasparov), White now often plays 6. Be2 and goes for a quieter, more positional game, whereupon black has the option of transposing into a schreveningen variation by playing 7..e6 or opt to stay in the najdorf by playing 7..e5. However, 6. Bc4 and 6. f4 are also respected methods for White to continue his onslaught. Since the 1990s, the English Attack 6.Be3 followed by f2-f3, g2-g4, Qd2 and 0-0-0 in some order has become extremely popular and has been intensively analysed.
