Using Fritz & Shredder to analyze, I come up with:
1.Bd2
[1.Nxc5 Bxc5 2.Bd2 ±]
1...Rxa4?
[1...Bxd2 2.Nxc5 Rb6 3.Nd3 gxf5 4.Nxe5
(4.exf5 Bxg5 5.Nxe5 Rf6 +=)
4...Ra6 5.Rxf7+ Ke8 6.Rc7 fxe4 7.g6 Kf8 8.g7+ Kg8 9.Nc6 Bc3
(9...Bf4 10.Rc8+ Kxg7 11.Nxd4 ±)
10.Ne7+ Kxg7 11.Nd5+ Kg6 12.Nxc3 dxc3 13.Rxc3 ±]
2.fxg6! Kf8
[2...Bxd2 3.Rxf7+ Ke6 4.Rf6+ Ke7 5.bxa4 +-]
3.gxf7! Bxd2 4.g6 Ra8 5.Rh8+ Ke7 6.Rxa8 Bh6 7.Re8+ Kf6 8.f8Q+ Bxf8
9.Rxf8+ Kxg6 10.Rg8+ Kf7 11.Rg4 +-
