Unamed oppening e4 e5, nf3 bd6


It's playable like 2...Qe7 is playable. It does not lead to a forced loss but is inferior to the standard moves like 2...Nc6 or Nf6. But if you like it play it!

I like it because white focuses his/her attention on forking knight and bishop (after nf6) and meanwhile you can start a queenside attack and eventually castle queenside.

If your opponent knows what he's doing he should be able to defeat you. After your move 2. Bd6, nothing has changed (your bishop still has the same diagonal to play on) except that your d-pawn is blocked. 3. d4 exd4 4. Bc4 and according to Stockfish white has a winning advantage.

I think that 2...Bd6 is a bad move, since 1. this is not an economical way to protect the e5 pawn, 2. the bishop there prevents the other bishop from developing normally, 3.whenever white will play 3.d4 the bishop will be exposed there. Ideally Black would like to play ...Nf6, ...0-0, ...Re8 and eventually ...Bd6-f8, but these are a lot of moves, and white can actively prevent this with great ease.
