Petroff Defense: Definition & Overview
Petroff Defense
Definition
The Petroff Defense (also written “Petrov Defense” or “Russian Defense”) is a symmetrical, double-king-pawn opening that begins 1. e4 e5 2. Nf3 Nf6. Instead of guarding the pawn on e5, Black counter-attacks White’s e-pawn with the knight, aiming for quick development and a solid, balanced structure.
Typical Move-Order
1. e4 e5 2. Nf3 Nf6
Main Branches
- Classical (Main Line): 3. Nxe5 d6 4. Nf3 Nxe4 5. d4 d5
- Cochrane Gambit: 3. Nxe5 d6 4. Nxf7!? — a swash-buckling piece sacrifice on f7.
- Steinitz Variation: 3. d4 Nxe4 4. Bd3
- Nimzowitsch Attack: 3. Nxe5 Nxe4 4. Qe2
- 3. Nc3 (Four Knights Hybrid): steering into quieter waters.
Strategic Themes
- Early Piece Activity. Both sides develop rapidly; the position often opens in the center by move 10.
- Symmetry & Simplification. Exchanges are common, producing equal or near-equal endgames that reward precise technique.
- Counter-attacking Solidity. Black’s setup is hard to crack, making the Petroff a favorite of players who are happy with equality.
- Hidden Tactics. Lines such as the Cochrane Gambit and 5. Nc3 carry significant tactical venom despite the opening’s “drawish” reputation.
Historical Significance
Named after Alexander Petrov (1794–1867), the first Russian chess professional, the opening was later refined by masters like Carl Jaenisch and Wilhelm Steinitz. In modern times Vladimir Kramnik, Viswanathan Anand, Sergey Karjakin, and Fabiano Caruana have wielded it at the very highest level, cementing its status as one of Black’s most reliable answers to 1. e4.
Famous Games
- Karpov – Kasparov, World Ch. 1985 (Game 16) — Kasparov equalized effortlessly under intense match pressure.
- Kramnik – Leko, Brissago 2004 (Game 14) — a must-win game for White that fizzled into a textbook Petroff draw.
- Caruana – Karjakin, Candidates 2016 — contemporary theory proving Black’s resilience.
- Kasparov – Karpov, Linares 1993 — Kasparov’s daring Cochrane Gambit was ultimately refuted over the board by Karpov’s accuracy.
