Game 25344
This should be immediately ruled a draw by the server. There is obviously no mating material.
As it stands, my opponent had to play ...Kb7 and hit 'claim draw' just to get the draw recognized.
It is not practical to code every such position, but how about the most common three:
King vs. King
K/B vs. K
K/N vs. K
Any position with exactly this material should immediately be ruled a draw by the server.

However as there is always the possibility of a timeout win/loss it is unlikely that the current situation will be changed. The situation doesn't arise often enough.
I am not staying I disagree, just that it may be more work than we think for something that maybe only occurs in 0.005% of games played.

There should not be the possibility of a timeout win or loss from a position that cannot possibly be won or lost on the board, even with the most unskilled play. [This is also a FIDE rule.]

Originally posted by orion25Ah, I thought there a situation where a Night could mate if the other guy 'cooperates' as you say.
No. B+N and B+B are winning. N+N only if the opponent cooperates. If in any situation a pawn is present, then there is a strong possibility the result is not a draw.
Same for Bishop, no mate when all alone with king?
I had a guy drag an opposite color bishop game out. I messaged offer draw, he just went on. I offered again (not bothering, just 'saying' "it's a draw, offer when you realize).
Finally after 30 moves he realized neither of us would win and offered a draw.

Are there any (ANY) situations where a Kv K & N, Kv K& B can stumble into a mate?

To demonstrate, try just placing the pieces on the board to form a checkmate. Even with the lone King stuck in the corner, there is always one free square:
Proof: No matter where he is on the board, the black King always has at least a 2x2 square to move around in.
The white King is capable of guarding two adjacent squares on the same rank [or file], but a Knight and Bishop can't. Thus, checkmate is impossible.
