I just played a game as black that started like this:
1. e4 e5 2. Nf3 Nf6 3. Bb5
But 3. Bb5 crashes out of all the opening books I have, yet I can't see why it's never played. Ok, c6 looks an obvious response, or even taking the pawn, but what's the problem for white here?
And advice please??
In Fritz Powerbook after 3...Nc6 is played the opening transposes back into a whole lot of different stuff (7572 games). So I'm
guessing (i.e. take with a whole shaker of salt) that White's preferred course is to make a Petroff a Petroff instead of risking "backing into" a completely different opening with 3.Bb5.
(Mega Database 2009 scares up 32 games with the move order 1. e4 e5 2. Nf3 Nf6 3. Bb5 -- I've been too busy banging out words to replace 2009 with Mega 2010 on this machine yet - I have 2010 on my laptop

As for those 32 games, there's nothing terribly interesting. The Bishop move looks like it was first played in 1978; the highest-rated player whose tried it was 2433 Elo Andreas Heimann (and he lost the one game in which he played it, back in 2008)
