The Petrov Defence: 1.e4 e5 2.Nf3... 3.d4 arises after 1.e4 e5 2.Nf3 Nf6 3.d4 and falls under ECO code C43. The chief sideline to 3. Nxe5, with 3. d4 White seeks to open the centre immediately and offers Black their choice of pawns to capture. 3...exd4!? is playable but less conventional as it allows 4. e5! to kick the knight. Typically this leads to trading both d- and e-pawns and opening the centre fully: the main continuation is 4...Ne4 5. Qxd4 (the Centre attack ) d5 (defends knight) 6. exd6 e.p. Nxd6 7. Nc3, although there are some sidelines (5. Qe2 was advocated by Steinitz ; 5. Bb4+ is the Tal gambit ). 3...Nxe4 is the main line and leads to a trade of e-pawns. White could retake immediately (4. Nxe5 or 4. exd4) but the normal move order is 4. Bd3 d5 5. Nxe5, where after ...d5 first Black doesn't have ...d6 to shoo the knight away. 3...d5 , the Symmetrical variation , passes the decision on what to take first back to White. Since Black has played ...d5 of their own volition, White may choose 4. Nxe5 and the positions can transpose after 4...Nxe4 5. Bd3 (4...dxe4? 5. Bc4 threatening Nxf7 Be6 6. Bxe6 fxe6 and Black has isolated double e-pawns ± ). With 6,603 games in the master database, it is a specialized opening choice.
