Went to see by curiosity if Rebel 10 can solve this problem. Solution was
impecable, right in 7 moves. Took 2 seconds on AMD 400Mhz. 28 M of hash table. I
don't know if Rebel solve by brute force or by selective search.

Through my mate solver (LLchess) found mate in 7 moves. No hash table. Could
solve only by brute force. On AMD 400 Mhz, time below 0.055 sec. The same
position on 486 50Mhz, 0.6 sec.
