2. axb5 Nxc4
if 3. Qxc4 axb5 attacking both Q and R
if 2. Bd3 c4 forking Q and B
if 2. Bxb5 axb5
O-O-O

This wasn’t easy to find, but I suppose that is because the eye is drawn to the king side with moves like Bxh3, Qg5, f5 etc. I basically went through all of these before considering anything on the queen side, and even then, I looked at Nxc4 first. Only after about a half hour did I finally notice the unprotected rook at a1:
1. ……b5!
2. ab5?! Nc4!
Why my initial thought of 1. …Nc4, 2. …b5 3.ab5 doesn’t work is that after black’s second move, there are still two pawns on the a-file, and white has time to retreat the queen from c4. Continuing:
3. Qc4?!
White will probably do better with 3.Qd3 to cover the threatened fork from d2, but he is still down a piece. Continuing:
3. ……ab5 wins with a double attack on the queen and the rook.
Back at move 2, white will probably do a bit better to retreat the bishop to d3, but black will still win the piece with 2. …c4 and 3. …cd3.
