Chess Opening Theory/1. e4/1...Nf6/2. Bc4

= Alekhine's Defence : Krejcik Variation = This riposte from White is not as dangerous as it looks. The possible sacrifice on f7 seems deadly if Black dares to take the offered pawn (/2...Nxe4/), but in reality, it just gives black a lead in development after 3. Bxf7+ Kxf7 4. Qh5+ Kg8 5. Qd5+ e6 6. Qxe4 d5! 7. Qe2 e5!.

If Black wants to avoid this, they may try to get the bishop out of c4 with /2...b5/. If White takes the pawn, Black can take the e4 pawn and he would have exchanged a wing pawn against a central pawn, but white gets a lead in development and an easier time castling.

Other options include /2...e6/ and /2...d5/.

To get back into more peaceful lines, Black can transpose to the Bishop's Opening with e5.

= Epine Dorsal = This opening lies along what was referred to in the 19th century as the Épine Dorsale pattern now more commonly referred to as the Italian Game.
