Win or draw???

It's a win since your opponent doesn't have time and you have sufficient mating material. Doesn't matter that your opponent can prevent promotion and it would be drawn with best play.

It is a win on time, but it would be a draw on the board.

The PGN says it's 0-1 for black. What's the discussion exactly?

Oh, that it is a draw.

->

"The PGN says it's 0-1 for black."

Anything unclear?

Read FIDE chess manual for the official rules.

I just don't understand these folks. There's no agreement or disagreement. Time is one of the inherent parameters of a chess game - not just the material count, position, or even forced checkmate line. All parameters count equally since they are rules. Time is not a meta-parameter - it's inherent. As in, logic.

Like basketball, a shot outside clock time doesn't count. Checkmate outside clocktime doesn't count. Winning position outside clocktime doesn't count.

0-1 is 0-1. Always. 1-0 is 1-0. Always. 0-1 = 1/2-1/2 is a logical fallacy. Get your mind together guys.

The Laws of Chess are clear:

"6.9 Except where one of Articles 5.1.1, 5.1.2, 5.2.1, 5.2.2, 5.2.3 applies, if a player does not complete the prescribed number of moves in the allotted time, the game is lost by that player. However, the game is drawn if the position is such that the opponent cannot checkmate the player’s king by any possible series of legal moves."

However, the Laws of Chess are not correctly implemented on chess sites.
Some positions are won per Laws of Chess, but drawn on the site.
Some positions are drawn per Laws of Chess, but lost on the site.

I can't find an exact source, but I believe that this is because chess.com implements USCF rules on the site. The USCF requires the player have sufficient checkmating material. Thus, while under FIDE rules a K+N against a K+R would be won if the player with K+R ran out of time, this would be drawn under USCF rules as it requires the player at least have an additional pawn or bishop besides the knight.

I am just kind of amazed that the guy messaged you later about a 10+ day old game.  WHY, if you are not above 2500 rating (career players), would you go back that far..?! 

It's a known drawn endgame but in order to achieve the draw, White must either get stalemated or achieve a 3-fold repetition in position.  Most likely, it will be stalemate [he'll just head for a1 and shuttle between there and b1; Black cannot dislodge him].

If White runs out of time before either occurs, he loses.

What was his logic as to why this is a draw?  Being a theoretical draw is different from actually achieving it.  For example, K+N+B vs K is a theoretically won endgame but how many would actually be able to pull it off?  The person with the extra material can't claim a win just because it's a theoretical win.

It is only a Draw if he plays it right. But regardless, because you technically have mating material aboard, the game is dependent upon the time always unless their is insufficient mating material. Yes he could technically stop you if he played correctly, but his time ran out, hence he/she loses the game. So he is wrong, and tell him to call 1-800-chess.com

His only basis was that it was theoretically drawn. He ran out of time.

I agree with you.  I think an exception would be a draw due to insufficient material [ie K+N v K; no pawns].  In that case, I think a draw is declared immediately.

You are correct.

To be honest, I don't understand the opening poster at all. So what happened is that you won a game, and then received a message from your opponent claiming that it was a draw. At this point a reasonable person would check the game in the archives, note that no, it was not a draw, then delete the message from the opponent (who is either insane or a troll) and that's it.

The position actually IS a known draw:  the White King will plant himself on a1 and move back and forth to b1.  The Black King cannot dislodge the White King and it will either come down to a stalemate with the Black pawn on a2, the Black King on either a3 or b3, and the White King on a1 OR Black stops defending the pawn and White captures and it's a draw due to insufficient material.

The problem is that White's time ran out before he could achieve either and that's why he lost.  For White to claim a draw would be like me claiming I had won the lottery because I was going to play the winning #s but I never got around to buying a ticket.

Chess.com implements something vaguely similar to USCF.  The difference between USCF and FIDE is only significant when the player that still has time has K+B or K+N or K+2N (in USCF those are only wins if the win is forced) while in all other positions FIDE and USCF agree.  Chess.com does not look at the position.  It just ignores all of the opponent's pieces except the king and looks to see if the unflagged player has a pawn and/or rook and/or queen and/or 2B and/or B+N and/or 3N.

If the position is blocked (think K+8P vs K+8P with the pawns locked up in a zigzag fashion and the kings stuck behind their own pawns) then USCF and FIDE would rule a flag as a draw (no legal moves leading to any checkmate) while chess.com would rule flagging as a loss (it only looks at K+8P vs K once the flagging player's pawns are discounted).

You didn't award yourself the win. Perhaps this person should complain to chess.com and not you
