Draw by timeout vs insufficient material?

Contact support, but Lagomorph might be correct. Switching tabs, and for such a long time, is not advised. As for the opponent, you can report him for stalling when you present your case. If he did this before, they will eventually close his account.

What if you have a knight and an opponent's a/h pawn on the side? Wouldn't that be a theoretical win for the side with the knight the the side with the a/h pawn times? Because white could put his king and pawn on the edge of the board and you can trap their king and mate. Plus here's a link to prove what I mean: Why is this a draw by timeout vs insufficient material? I literally have forced mate in 1, clearly my material is sufficient. : r/chessI believe chess.com should clearly fix this issue.

There are some edge cases where there might be a forced mate but as far as I'm aware there are no plans to check all such games to look for that.

Nice little knight mate with 2 pawns..

When you or your opponent runs out of time, you will be given the best result possible. If you only had a knight, then it would be timeout vs. insufficient material. However, if you had a pawn, you would win the game. This is because the singular pawn can promote to a queen or rook, and they are able to mate the king alone.

Since the thread was re-resurrected the differences in the time-out rule may as well be revisited.

1) FIDE - if you run out of time and there is any legal way for the opponent to deliver a checkmate (opponent's best moves versus your worst moves) then running out of time is a loss. If there is no legal way for the opponent to checkmate you then it is a draw. White Ke1, Pa4, Pc4, Pf4, Ph4 vs Black Ke8, Pa5, Pc5, Pf5, Ph5 is a draw because there is no legal way to mate. White Qa8, Rb7, Ph2, Kh1 vs flagged Black Kh8, Bf3, Rg2 is a draw because Black's only legal move is Rg8# leaving White with no legal series of moves to win. K+N or K+B vs K+P are wins regardless of the position because the pawn can be promoted to a Bishop, the King can move to a corner with the bishop adjacent on the file, the opposing king can move two squares away on the rank and either the bishop can be mating on the long diagonal or the knight can mate from the square next to the attacking king (Black Kh8, Bh7, White Kf8 and either Bb2 or Nf7)

2) US Chess (rebranded from USCF) - Almost the same as FIDE with an exception where the unflagged player has either K+B or K+N or K+2NwithNoPawnsOnTheBoard. In those exception cases it is only a loss when the unflagged player can force a mate (the other player needs to have more than a lone king and already be in a position where the escape squares are blocked and cannot be unblocked. The example from EndgameEnthusiast2357 is a win because it is one of those rare positions where the King and lone Knight can force checkmate against he King and two pawns. There are a number of other differences between FIDE and USCF but the OTB-only game-ending moves (other than two, formerly three, illegal moves triggering a loss in FIDE but not USCF) are the same, including the 5-fold repetition and 75-move rulings that a TD/arbiter can impose. Things like cell phones and default times are different but they are not actual moves being played (note that the definition of illegal moves, that need to be handled before the game can continue, has some differences such as leaving a pawn on the final rank is illegal in FIDE and merely improper in USCF - you see that a lot in casual play when the newly minted queen is just going to be immediately captured anyway).

3) Chess.com - The position is ignored. If your opponent has at least a Pawn or a Rook or a Queen or two Bishops or a Bishop and Knight then it is a loss. Maybe also if the opponent has two Knights but I haven't checked on that. Thus the positions cited in the FIDE example would be losses when flagging on Chess.com even though there is no legal way to deliver a checkmate against you. In the K+N vs K+2P example above Black has 11 opportunities to simply flag for a draw on Chess.com instead of getting checkmated (or flagging for a loss in FIDE or USCF).

The contents of this page summarised:

A draw by timeout vs insufficient material means that one person has run out of time while the other has insufficient mating material. Although one of the players has run out of time, the other at that point does not have any way to checkmate their opponent if the game continued, therefore meaning that that one player cannot win. Therefore the other player cannot lose, meaning that when they run out of time, it's a draw, not a loss for them.

And thanks to the other people above who have explained this extremely well
