The Chekhover Sicilian arises after 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Qxd4 and falls under ECO code B53. In this unusual line, White takes back on d4 with the queen rather than the knight, sidestepping the main Open Sicilian positions. Developing the queen so early is generally considered a dubious strategy since it creates a target that allows the opponent to gain tempo. In this case, however, White's queen is relatively difficult for Black to exploit, since the ...d6 pawn limits Black's ability to attack it effectively. If Black plays 4...Nc6 to challenge the queen, White responds with the pin 5. Bb5 Bd7 6. Bxc6, and a typical continuation runs 6...Bxc6 7. Nc3 Nf6 8. Bg5 e6 9. O-O-O Be7 10. Rhe1 O-O. Another approach is 4...a6, which prepares ...Nc6 while preventing the Bb5 pin, thereby ensuring the queen will have to move. From there, play might continue 5. c4 Nc6 6. Qd2, or White can steer toward a simplified endgame with 5. Be3 Nc6 6. Qb6 Qxb6 7. Bxb6. With 3 million Lichess games across all rating levels, it is a specialized opening choice.

Common Mistakes to Avoid
- Ignoring the opponent's kingside attack: In many Sicilian lines, White will castle queenside and push pawns toward your king. If you don't create counterplay on the queenside or in the center, White's attack will arrive first.
