I did it in less than 5, so I'm sure my machine can, too. This one isn't complicated enough to show horizon effect.

Sol: 1. Ra8 Kh1 2. Rh8+ Kg1 3. Kd2 Kf2 4. Rf8+ Kg1 5. a4 Kh2 6. Rh8+ Kg1 7. a5
Kf2 8. Rf8+ Kg1 9. a6 Kh2 10. Rh8+ Kg1 11. a7 Kf2 12. Rf8+ Kg1 13. a8=Q Kh2
14. Rh8+ Kg1 15. Qe4 ~ 16.Qe2#

Interesting! Shredder finds it in 26 seconds

You found it in less than 5 seconds? Are you a Grandmaster? To a patzer like me that's amazing!

I'm sure he meant five minutes
