[edit] Petrov's Defence
[edit] 2...Nf6
Black chose to counter-attack. Many continuations are possible for White.
-
- 3. Nxe5 is the main line (or Classical Variation). In this line, it's not advised for Black to take White's pawn before having chased the knight. There is a famous trap : 3...Nxe4 4. Qe2 Nd6?? (or 4...Nf6??) 5. Nc6+ and Black's queen is lost.
- With 3. Nc3, Black can easily transpose into Four Knight's Game with 3...Nc6. This option is sound when White wants to avoid the sharp lines of the Petrov's Defence.
- 3. d4 is the Steinitz Variation. Both players will usually plant their knights in advanced positions. Exchanges often occur in this line to avoid having a too powerful enemy knight in front of the king.
- 3. Bc4 usually transposes into Two Knight's Defence (a variation of Italian Game).
- 3. d3 is, according to statistics, a much more effective move than it looks, though it's rarely played. White builds a strong fortress and Black is now forced to abandon the Petrov's lines and to defend his pawn.
