I'm pretty sure all those old ending "allowances" got changed again, to a standard 50 moves.
In fact it is a forced mate; why would the previous rule changed be abandoned? Does not compute! Excellent links from Prawn and chessisgood. Thanks guys!
I recall several years ago that in B+R+K vs. R+K endings the 50 move rule was extended to 100 moves for this specific ending. Can this rule change be found anywhere here? This was a result of a computer showing a forced mate in about 60 moves. Thanks
