Hello guys, how is that possible this position is draw if my opponent runs out of time? If he had 1 Queen against Knight yeah it was draw since I cant mate him, but look at this position. Where can I ask to support? What do you think? Is it a mistake? I think totally yes

That's the rule.

The rule says this: if my opponent runs out of time and there is at least 1 position in which with my pieces can mate him, he loses. The pawn can become a Rook or Bishop or Knight and then there should be a position in which I can mate. So the position is theorically winnable by me, so why its draw? It doesnt count computer analysis, you have to find 1 mate position only to prove the victory. Its a fide rule. I tried in lichess, same position, I intentionally run out my time and of course the site gave me a loss!! So I dont understand why chess.com should give draw ... Its universal rule

What does ‘insufficient mating material’ mean?

So you’re playing a game of chess, and are getting near the end. There are only a few pieces left, and one more is captured! But then… the game ends in a draw, and you get the message ‘insufficient mating material.’ What does this mean? 

The insufficient mating material rule says that the game is immediately declared a draw if there is no way to end the game in checkmate. 

The most common way that this happens is when the game is down to just two kings. There is no possible way to get checkmate--even if your opponent blunders--so the game is declared a draw.

There are other combinations that will cause a draw that are not as obvious:

If both sides have any one of the following, and there are no pawns on the board: 

  • A lone king 
  • a king and bishop
  • a king and knight

In the above scenarios the game will end in a draw, because it is not possible to force mate against a lone king with that material. You have a king and bishop your opponent has a king and bishop? It’s a draw! A king and bishop vs a king and a knight? Draw! And so on. 

-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.

I am sure that the quoted chess.com article misrepresents the USCF rule. Because it is complete nonsense in this form.

Hypothetical: wouldn't you be so angry if you are up 5 pts of material & your opp. only has a Knight, but you are 30 seconds behind on the clock and you get flagged for a loss? I think that would be unfair because you obviously played a far better game, besides a little clock mismanagement. The side down 5 pts shouldn't get a win when they played a terrible game but played that terrible game a little faster than you played your crushing game.  

I had to test the K & 1B vs. K & 2Ns. This should be an auto draw according to everything I know but the game does indeed continue?

Can anyone explain why this isn't an auto draw? Because it's going to be a draw due to the 50 move rule regardless, so why doesn't it just stop the game when it's gets to that situation?

Here is the USCF rule for insufficient material to win on time:

"14E2. King and bishop or king and knight.
Opponent has only king and bishop or king and knight, and does not have a forced win."

It differs from the FIDE rule as it requires checkmate to be forced rather than possible by any series of legal moves.  

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).

So there's a helpmate possible and that's a win by fide rules? Wow! When was that change made?

On chess.com this is a draw.
On lichess it would have been a win.

Different entities handle this differently.

The language here is sloppy, but most players wont notice... and it gives examples so I think it does a good job explaining.

But sure, the language suggests that if you run out of time but can't force a mate then it's a draw... but that would mean all sorts of positions would end in a draw when this is obviously not the case.

@JohanVA - The FIDE rule has always been helpmate wins on time, e.g. lone bishop vs lone bishop of same color squares is a draw, lone bishop vs lone bishop of opposite color squares is a win. It's the USCF rule which has changed, it used to be the same as the FIDE rule. I don't know when the change happened, but I think they still followed FIDE in the 5th edition of USCF rulebook which came out in 2003.

That's FIDE.

USCF is different and chess.com is different than that as they are too lazy to program the forced mate scenario.

I see. Guess I remember that wrong then or maybe we didn't read the rules all that well back in the day, heh...... The problem never presented itself anyway.

Thanks for the info.

Here is the complete rule.  As you can see, it's limited to a few situations:

14E. Insufficient material to win on time.
The game is drawn even when a player exceeds the time limit if one of the following conditions exists as of the most
recently determined legal move (effective 1-1-19) See also 15H, Reporting of results:
TD TIP: Remember a 14E draw claim is first a draw offer (Rule 14, The Drawn Game).
14E1. Lone king.
Opponent has only a lone king.
14E2. King and bishop or king and knight.
Opponent has only king and bishop or king and knight, and does not have a forced win.
14E3. King and two knights.
Opponent has only king and two knights, the player has no pawns, and opponent does not have a forced win.

I don't know why so many people find it hard to understand that chess.com games are not USCF (or FIDE) rated, and don't follow USCF (or FIDE) rules.

Chess.com essentially uses a modified version of USCF rules.  Their "insufficient material" rule was devised around 2010 when not only was there an "insufficient material" rule, but also an "insufficient losing chances" rule (now obsolete unless analog clocks are used).  Chess.com opted for simplicity to make the programming easier.

When I linked the chess.com rule, you quoted the USCF rule saying it's the "complete" rule.

It's the "complete" USCF rule, but the link I gave is the "complete" chess.com rule.

Hi. Yes, you do not have sufficient mating material, that is why? 

KnightCharles

A Knight and a King against just a King is not sufficient mating material.
