I think it would be drawn already on a 9x9 board. On an 8x8 board the lone king gets very close to escaping while being driven to the 'matable' corner. The extra step the shepherding king has to do on a 9x9 seems to be too much of a delay...
For each step of the lone king, the mating posse has to organize 3 pieces (2 of which are short range and have to pursue the lone king) and is thus slower in moving.

Originally posted by apawnYes, very good link, I agree. Also, if anybody has a B+N+K vs K winning game please post it here.
Nice link you have there TheMaster37 - thanks!
You all are right of course about the (odd)x(odd) board, and with the right bishop the mate should be easier than on an 8x8 board.
On a 10x10 board I suspect the B+N+K vs K is a draw. Proving it is another matter...
Originally posted by apawnThat triangle cornering technique shown in the link really worked out well. I will have to test this out if I get the opportunity. Thanks for the game apawn
