Resolved: Erroneous draw?

Sort:
Mijin

Hi

After a drawn out endgame all that is left on the board are the two kings and a rook belonging to my opponent. Fortunately, my opponent has just seconds to mate me, and fails, hes clock goes to 0:00.

However, the message box then says "Draw by insufficient material"

Does it adjudicate such situations as a draw?

N.B I didn't take the rook, and the game in my records shows a rook still on the board and my final move as Kg5 (i.e. no "x")

Yes, it's a draw because you must have sufficient mating material to force mate. 

Mijin

Huh, I didn't know that. I thought when your time runs out, that's that, you lose.

 

Are these the standard rules? I think some of my offline games with friends we may have been using incorrect rules if so

Thanks.

But now you've made it easier for people to see 61...Nc7??

 

Thinking about it, I could see why there might be a rule that this is a draw...white doesn't need to make any moves. If white could press a button and instantly make a random move, they'd be guaranteed a draw by repeatedly pressing the button. So you can make a case for calling it a draw.

NJH: A rook and a king is sufficient material, but a lone king is not, so a draw is the correct result here.  

According to official rules, if one player runs out of time and the other player could not possibly perform a checkmate under any legal sequence of moves, the game is ruled a draw.  Put more simply, Mijin: your opponent couldn't win because he ran out of time and you couldn't win because you didn't have sufficient material.  Since neither player could win, a draw was the result.

Mijin

Doh...and 24...Re8??

*two* occasions I could've won a rook.

 

I was tired...I'd had a long day...it happens to all guys from time to time...Laughing

 A draw is the correct outcome.  Your opponent ran out of time, and you only had a King.  If you had a pawn and your oppnent ran out of time then you would have gotten a win.

Mijin

Well, makes sense. Think I might have made the wrong ruling on one or two "real-life" games, but at least now I know.

Thanks all.

You have insufficient material to checkmate. You cannot win.

http://www.fide.com/component/handbook/?id=124&view=article

Rule 6.9 "Except where one of the Articles: 5.1.a, 5.1.b, 5.2.a, 5.2.b, 5.2.c applies, if a player does not complete the prescribed number of moves in the allotted time, the game is lost by the 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.".

King and pawn vs King is not always a win. Depends on the position. Accurate play is also helpful.


The rule states that if checkmate from your opponent is possible via any series of legal moves then the game is a loss when you time out.  Otherwise, as was the case here, a draw is declared.

They don't have to be good moves -- helpmates count.

Yes, I think that chess.com has a simplified implementation of this rule that is not 100% accurate.  Not so much a bug as a known limitation.

From this thread:

http://www.chess.com/forum/view/help-support/no-mating-material--draw

TheGrobe

As the rule is written, K+P vs K is a draw when the K+P side times out, and a loss when the K side times out regardless which pawn it is or any other considerations.

Best play, such as the opposing getting to the queening square of a rook pawn, is not considered, only whether there's a series of legal moves that lead to mate.

TheGrobe

Ahh, fair enough -- excluding time outs it can be any pawn, really, depending on who has the opposition.

Mijin
Rather than start a new thread in quick succession, can anyone help me out please with what happened here?
In this game I blundered my queen away midgame but thought I had saved the game when I found perpetual check. Unfortunately, no draw was declared, even though we repeated several positions more than 3 times. All the time I was clicking away at the "draw" button, and nothing happened. Eventually I lost on time. 
What gives?
Mijin

Oh, and the perpetual check begins from move 43

Mijin

Ah, I've just read the help + support.

According to that, I have to hit draw while it's my opponent's move. I can't be sure that that's what I did: maybe I kept hitting it on my turn only.

 

Just to say though: I think that's a weird way of doing it. If my opponent is sufficiently fast, I won't get a chance to claim a draw?

Correct.  Your opponent can negate your correct claim by moving, especially through premove or conditional move, before you can click the button.  http://www.chess.com/forum/view/suggestions/correct-draw-claiming
