You can't resign when the game already ended.

I never said that you can resign after the game has already ended. That never was in question. We were not talking about games which have already ended. Your reply does not make sense.

I am also of the opinion that people that would in practice resign (for whatever reason) when they have a bare King are likely to be removed from a tournment, even if the FIDE rules do not explicitly say that you cannot do it.

So I will adapt the claim-verification algorithm of WinBoard accordingly: he who wins for whatever reasons (opponent time forfeit, resign, illegal move, crash, of false claim) will get its result downsized to draw if he has a bare King. (In engine-engine games with '/testClaims true'.)

Note you should not turn this option on in variant losers, suicide or giveaway.

From the FIDE Laws of Chess:

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

5.1 b. The game is won by the player whose opponent declares he resigns. This immediately ends the game.

I quote this simple rule because it is the only occurrance of the word "resign" in the whole document, and it is unrestrained. In other words, there is no rule which would say, you're not allowed to resign if the opponent has no material which is capable to mate. There is no such rule, that's why I think it is allowed to resign even in such cases.

Although it would of course seem very weird to do so!

If someone would try to resign in such a position, I think the referee can interfer ( and disqualify someone)

It is clear that if you resign in king against king it is a draw because the game was already over when you resigned.

If you resign when you have king and queen againat the opponent king
then it is not the same situation so it may be possible to decide that you lose the game.

A loss for one player does not have to be a win for the second player so it is possible to decide about a loss for the player who resigned and a draw for the player with only king.

That is an interesting point, Uri!

Are result messages like 0-1/2 and 1/2-0 allowed in PGN?

I do not know about pgn rules but they already happened in tournaments.

I remember a case that one player lost because his phone rang when the opponent got only a draw.

Both players did not like the result but this was the result of the referee.
The loser had objectively winning position when his phone rang.

Edit:I can add that the rules force the referee to decide a loss for the player that his phone rang but they do not force him to decide about a win for the opponent.

We were (of course!) not discussing lone king against lone king. Your remark is useless. We were discussing situations where ONE player has the lone king but NOT the other player, and THE OTHER player exceeds the time limit, or resigns. That was what we were discussing Uri. Ok?

Some people seem to have reading troubles.

Don't forget to do this with KNK, KBK as well. In fact I'd add KNNK as well.

If you want to loose the game
let your mobile ring.

He means where there is insufficient material to mate left on the board.

[Mike S.]

In KNN-K, mate is possible against most unskilled play (as it is in KB-KN). So, these are not "inavoidable" draws by FIDE rules.

But I won't contradict if in computer chess, an interface and/or an engine declares these drawn, for practical reasons (except mate in the next move is possible).

[D]7k/8/7K/4n3/5n2/8/8/8 b - - 0 99

99...Nf7#.

Which means, if you have this position:

[D]7k/8/7q/4n2K/5n2/8/8/8 w - - 0 99

You cannot "declare" the draw after 99.Kxh6. Because the reply is 99...Nf7#.
