28 ( +1 | -1 ) ScandinavianAfter 1.e4, d5; 2.e5?! black can choose a trasposition in other defences or remain in the Scandinavian with, for example, 2...Bf5. It looks like an advance variation of the Caro Kann, but black's pawn is on c7 and black can push it on c5 saving a tempo. 1.e4 d5 2.e5 Bf5 is classed as Scandinavian also in ECO (Enciclopedia of Chess Openings)
13 ( +1 | -1 ) 2... c5also leads to a good position. White's 2. e5 is not particularly good. And 1. e4 d5 2. e5, unless it transposes (e.g. 2... e6 is a French) is still a Scandinavian Defense.
