Not so good. Takes Crafty 4 minutes to find this move:
11-> 30.03 0.88 1. Bc5 Qe8 2. Ne2 bxa4 3. Bxd6 Bxd6
4. Bxa4 Bb5 5. Bxb5 axb5 6. Rxa8 Rxa8
7. Rxa8 Qxa8
12 1:12 0.92 1. Bc5 Qe8 2. Bxd6 Bxd6 3. Nf5 Bxf5
4. Qxf5 Rab8 5. axb5 axb5 6. Ra7 Ra8
7. Rxa8 Rxa8 8. Rxa8 Qxa8
12-> 1:18 0.92 1. Bc5 Qe8 2. Bxd6 Bxd6 3. Nf5 Bxf5
4. Qxf5 Rab8 5. axb5 axb5 6. Ra7 Ra8
7. Rxa8 Rxa8 8. Rxa8 Qxa8
13 2:25 0.88 1. Bc5 Qe8 2. Kh2 a5 3. axb5 axb4 4.
Rxa8 Rxa8 5. Rxa8 Qxa8 6. Bxb4 Nxb5
7. Nf5 Bxb4 <HT>
13 4:06 0.90 1. Bb6 Qe8 2. Qf3 Be7 3. Nh5 f5 4.
exf5 e4 5. Qg4 Bg5 6. Ng3 e3 7. axb5
axb5 8. Rxa8 Rxa8 9. Rxa8 Qxa8
(2) 13-> 4:06 0.90 1. Bb6 Qe8 2. Qf3 Be7 3. Nh5 f5 4.
exf5 e4 5. Qg4 Bg5 6. Ng3 e3 7. axb5
axb5 8. Rxa8 Rxa8 9. Rxa8 Qxa8
So that isn't a particularly hard one. Of course, Bb6 is only a tiny bit
better than Bc5, so such a small difference is not a particularly good example
anyway...
