I don't know Bob. This is interesting. In the book "Endgame Magic" by Beasley
and Whitworth the authors say in an appendix:

"In the absence of pawns, two minor pieces against one is usually a draw, but
the special case of two bishops against a knight has been proved by a computer
to be a win."

I'm not a FIDE rules guru, but I believe the 50 move rule had been extended in
special situations of which this_may_be_one. This point has been overlooked in
the discussion.

Any FIDE rules experts here?

Cheers,
Jim
