                                    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...
