We had this position a while ago. I stated that it is not very difficult for
computers to find. But of course, I would be more than proud to ever find such a
comnination in a real game!

Ikarus (K6/2-475MHz, 8MB Hash => rather slow hardware, mediocre software...)
finds the correct move in 14 seconds:

       9   11   +0.85  1. a4 b4 2. c4 Qc5 3. Nc2 Nb6 4. Rxb4 Rad8 5. b3
       9   14 FailHigh 1. Nxb5+! axb5 2. Rxb5 Qc6 3. Rdxd5 exd5 4. Qe3+ Ka6 5.
Rb4 Qc7 6. Qd3+
       9   15   +2.12  1. Nxb5+ axb5 2. Rxb5 Qd6 3. Rd4 Nc3 4. Qd2 Nxb5 5. Rxd6
Nxd6
      10   17 FailHigh 1. Nxb5+! axb5 2. Rxb5 Qd6 3. Rd4 Nc3 4. Qe3 Ne2+ 5. Qxe2

      10   22   +2.98  1. Nxb5+ axb5 2. Rxb5 Qc6 3. Rdxd5 exd5 4. Qe7+ Ka6 5.
Rb3 Qb6 6. Rxb6+ Kxb6 7. Qd6+ Ka7
      11   34   +3.06  1. Nxb5+ axb5 2. Rxb5 Qc6 3. Rdxd5 exd5 4. Qe3+ Ka6 5.
Rb4 Qb5 6. Rxb5 Kxb5 7. Qd3+ Kc5

I expect many commercials to be even a lot faster, but I leave that to others to
find out...
