Mating with Bishop and Knight on a large board


https://chess.stackexchange.com/questions/1432/kbn-vs-k-checkmate-on-nonstandard-boards

Not convinced I am, young Jedi.

Anyone with a formal algorithm? (It suffices to give one that drives
the king from the wrong to the right corner. I.e., that manages to
get the critical Kc5 Nb4 Be5/Kb3 -with black to move- in time,
and the black king also can't stay on the upper side.)

Obviously on any board with a correct corner color up to 14x14 the win is trivial, as outlined in the thread.

So it's really just for boards from 16x16 onwards, or possibly 18x18 onwards, that needs to be researched.

Whereas I slap my head for not remembering the posting, the difficulties
in Kriegspiel and large board are due to completely different sources.
I don't think it helps.
