Ok Keith, I agree that I exaggerated, after mine unhapelly idea to
translate "Leitão" for the English language, the minimum that I must
have done would be to write some thing about chess computer, but
never is late for making right the things. See this interesting
game of Leitao, perhaps the only one that I have seen with an
endgame KRPKB.

Position after 60....Kxa5:
r7/8/p7/k7/8/3B4/4K3/8 w - - (see the entire game below).

Blacks wins?  Bruce Moreland, consulting tablebases, said that
yes, in reply to my post. Until today I do not know which  was
the decisive error of the blacks, therefore the game finished
with a draw.
