How is this position draw? Insufficient pieces.

So in this game I am playing with white pieces.

My opponent's time has run out but instead of I winning the game, the game ended with draw? That is mistake.  If there is a possibility of you can mate your opponent than you should have won the game. Imagine my opponent has his pawn at h2, his king at h1. My king at cf and my knight at f2 then it is mate. I still have a possibility of winning the game.

The game plays as long as one player has chances of winning. Instead of an automatic loss, a timeout is considered as losing chances of winning. So if you have insufficient material to win, and your opponent has insufficient time to win (0), it's a draw.

Chess.com (along with most other online sites) consider this insufficient material because having just a single knight would rely on your opponent to help you (in almost every single case).

From the official support article above (this is somewhat similar reasoning to your case with a single knight):


-A king and two knights

This scenario is a bit different. On Chess.com a King and two knights is only considered insufficient material when against a lone king. So if a king and two knights versus a king and a bishop is on the board, the game will continue, however, if the bishop or one of the knights is lost, the game will then end in a draw. This is because, counterintuitively, it is easier to check mate a king and another piece with two knights, than it is to checkmate a lone king with two knights.

Some of the above situations might be treated slightly differently in FIDE or USCF tournaments, or on other sites.

In the specific case of two knights versus a lone king, USCF rule specifies that the game is drawn because there is no forced mate. The FIDE rule specifies that the game is drawn only when there is no possible mate, and so would not include two knights vs a king as an automatic draw, since it is technically possible to checkmate the king if the king 'helps' you by making specific moves to allow the checkmate. However, Chess.com follows the USCF rule in this case, and calls two knights insufficient mating material because the checkmate can not be forced.
