I believe this would be +/- at least, if not +-. I mean black gets totally ripped off in 2 moves.
1.a5 bxa5 2.Rb1 Bb7 and black defends e5, correct? 3.Qb2 may pose problems in this position since Bb7 and Nd6 can't move. But what I mean is that a computer would probably defeat us with a pawn up in such a position if we can't destroy him immediately.

Also after 3.Qb2 I think that black might play 3...Qc8 followed by 4...Ba6 and play against our c4 pawn.

I'm not using any chessboard, so I may be blind.

After Bb7 we take the pawn on e5 with Qxe5. I must say i really like our position after that. See below.

After Nxc4, I think Black would be dead via Qe6+ Sven. Nxc4 is ??? to me anyway (and I hope I've seen it right). It just throws a knight away, doesn't it?

It does.

I think this is the best moment to play a5.
Ray, which moves have gotten the most votes?

Oops ... :oops:
Right, loses a knight.
Black could start hunting the queen (after Qe6+ Kh8 Ndxc4 for instance) with Rf6 Qg4 (Qxe7 Re8) Rf4 and try to draw but that's another issue and was clearly not the intention of bxa5?, although still interesting.

I should use a chessboard at least ...

I would still play 21.Bg4.

After 21.a5 bxa5 22.Rb1 Bb7 23.Qxe5, black does not play 23...Nxc4?? (as I learned now) but improves his position slowly with 23...Rf7 followed by 24...Rdf8. e6 is no longer a strong point for white in this position unless white could bring his bishop to e6. Maybe white gets equal play but I think this is a position where a computer would dominate us. Doubled rooks, pair of bishops with one of them very strong (c7), passed pawn (although doubled/iso/a-file), and white problem on c4.
