Interesting question, surprising results...

Current version -> 1:24 (11 plies) (tested within Rebel)
Century 1.2 -> 2:15 (11 plies)
Century (cdrom version) -> 18:15 (11 plies) (painful)
Rebel10 (cdrom version) -> 1..Bf8 not found at 12 plies. Stopped after 28:00.

After this cold shower I dropped the idea to test this position with
Rebel 8 & 9 too.
