Help please

I have repeatedly “lost” when my opponent only has a single bishop and king. There is no way for him to mate me. For some reason when my time runs out, I lose. When it’s reversed and I have the single piece, the system claims a draw. I feel like it must be some setting on my part but I’ve checked all my settings. Can someone please help me?

It’s also happened when my opponent has a single knight and king.

can you send an example?

Yes, how do I reply with an image?

Here is the game.

Mate is possible. Your king in the corner, your knight blocking one square, his king covering the other two, his knight delivering mate.

A knight can win against any non-queen
A bishop can win against an opposite-colored bishop or a knight, or a pawn (as it can always promote to a knight)

There was another thread about this just a few hours ago so I won't bother linking the FAQ.

Maybe worth mentioning that this would be a draw on chess.com (which uses USCF rules) but a decisive result on lichess (which uses FIDE rules).

To explain it a little more in-depth, FIDE rules (which Lichess uses) only require a mate to be possible. It assumes the worst possible play, even in theoretically drawn positions. Insufficient mating material only occurs when a checkmate cannot possibly occur by any sequence of legal moves. I've demonstrated this on the poor computer.




Realistically, such positions will not arise, but they could, and so the material is considered sufficient and if the other player runs out of time, they will lose. Here is an example with the material in your game.
