My opponent ran out of time and draw when I can mate him?

Yeah but the problem is that my opponent had a pawn, that could help his king to get trapped in my favour, in Fide it's won. Now I read this doesn't work in USFC which is chess.com rule

Black was 2100+ and would promote  unless you sacced your knight. He wasn't going to lose this except by a series of incredible  mouseslips. Wanting a win on time so much that you even started this thread seems petty to me. If the roles had been reversed to favour you I doubt you would be complaining.

in the referenced game, Black timed out with  K + P.  White has K + N.

FIDE:  Win for White (I'm sure that there is a series of legal moves leading to mate}.

USCF:  Draw {no forced mate).

I'm sorry if this was covered but can someone link to me how someone has "a legal series of moves leading to mate" with just a King and a Knight, hell give the king 2 Knights. 

Would anyone explain to me why chess.com doesn't end the game when a K&B go against a K & 2 Ns? Why isn't that an immediate draw? Try it in the analysis tool. I really don't get this one.

No problem. Here's the position from the OP's game.

With two knights, black doesn't even need any material.

I've been playing chess for almost 2 years and was thinking this entire time 2 Knights couldn't checkmate. Mind blown thanks!

Two knights can't mate by force. Black could have avoided the mate by 3...Kf1.

There are two ideas behind "helpmate" winning on time: (1) The players cannot be expected to make the best moves. (2) The rulebook should not presume anything about what actually is best play. In my first copy of the FIDE laws which I read back in the 1970s, it even explicitly said this, something like "we are not going to give exceptions here which might be overturned later by analysis".

It may seem unfair for a player with only a lone pawn left to win on time against an army of opposing pieces. But think about it, the "army" player knew how much clock time they had at the start of the game. All they had to do was, at some point, stop capturing pieces and actually try to checkmate. Failure to do that is what cost them the game. And if they didn't want to lose, just capture that last pawn before time ran out. I say this as the player who is usually far ahead on material only to watch the clock run out.

The guys in my club try to play without time and it drives me bonkers. I try to tell them clock management is part of the game. A part of my game I've worked on, and they're taking that skill away from me. They just say "Well, it's just a casual game." 

I won't play without time ever again.

That's a fair pt, but we get 3 hours a week to play OTB and I want to get in at least 5 games in that time. If I play 2 games without time (one as white one as black as one does) that is going to add up to at least half my playing time depending on the opponent.

All the ole timers play clockless & for me it's just chess blasphemy because I learned on here and you don't get a choice. Get better at clock management or lose. The worst ones are the newbies though. I don't mind giving them a practice game or whatever but unless I'm actually giving them a lesson of sorts, ya know candidate moves and explaining the pros & cons of a move, it is brain numbingly boring. 

The guys that play with a clock are also online players and they are way better than me so then the clock turns into my enemy with those guys, so I can't win for losing. 

To your overall point, I started this club back in February at my library and it's a small town (40k), and it has really grown. Every Sunday we have at least 15 actual chess players and at least that many spectators. I'm quite proud of it. The only club in town!

Try yoga.

It's a draw. Black even has the advantage having the pawn. And he would promote to a Queen, not a damn Bishop, unless he was intentionally trying to lose. Its simply a draw and you should know better so please quit your complaining. If anyone should be complaining, it should be black.
