Poisoned Pawn Variation
The Poisoned Pawn Variation is a highly complex and sharp line in the Najdorf Sicilian. It arises after the moves:
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7.f4 Qb6
In this position, Black threatens to capture the b2 pawn, which is considered "poisoned" because taking it leads to a very dangerous position for Black. However, not taking the pawn allows White to build up a strong attack.
Key Ideas:
- Black's queen move to b6 creates immediate tension by threatening the b2 pawn.
- White must decide whether to defend the pawn or allow its capture and seek compensation through rapid development and attack.
- The position often leads to sharp, tactical play with both sides walking a tightrope between attack and defense.
Fischer's Contribution:
Bobby Fischer extensively analyzed and played this variation, demonstrating that Black could survive the early attacks and even emerge with winning chances. His deep preparation and understanding of the resulting positions made him nearly unbeatable with this line.
Modern Perspective:
Today, the Poisoned Pawn Variation remains a respected and feared weapon in top-level chess. While computer analysis has revealed some of its secrets, it still leads to incredibly complex positions that challenge even the world's best players.
