I think rule 6.9 must be applied here.

It's commonly agreed that 2 knights alone cannot force a mate.
Hence the result must be draw.

Even KNNK is not a draw under FIDE rules. Although it cannot be forced, two knights can deliver mate.

And, like Graham said, it can sometimes be forced with other material on the board. This is mate in 4, for example:

[d]k7/4N3/1K6/8/3p4/3N4/8/8 w - - 0 1

[Thanar]

Fide Laws of Chess - 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."

The exception articles from the first sentence do not apply here (checkmate on the board, declared resignation, stalemate, dead position, draw by agreement).

So the game is lost by the white player unless black "cannot checkmate [the white] king by any possible series of legal moves."

But there is such a legal series of moves whereby black checkmates white. For example, after 1.Rxb7+: 1...Kxb7 2.Ka4 Nb4 3.Qa3 Nc2 4.Nd2 Ka6 5.Nb3 Nb6#

[d]8/8/kn6/8/K7/QN6/2n5/8 w - - 8 6
Therefore black wins.

Now that's we're at 75%, I can thank you for not letting me down!

Yes, under FIDE rules, this is a black win since the rule states :

Fide Laws of Chess - 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."

USCF rules are different, and under USCF rules, this game is drawn. But good luck trying to find USCF rules online - USCF wants you to buy their rule book online.

OK, convinced!

Win to black, as it is still possible to mate with two knights with other material on the board.
Highly unlikely of course, but that's the official line.

Graham is completely correct.

In fact, it is/would be extremely amateur (or sneaky) of the white player to claim a win based on "tablebases" after losing on time...a loss is a loss.

And with regard to the remaining material, all that needs to be demonstrated is that mate is possible, not that mate is able to be forced.

Therefore black wins because mate is theoretical possible (probability not being of importance).

This is a very basic rule and anybody even with a little experience playing online will have experienced its application hundreds of times.

This is loss for white
White didn't complete moves in time


Also I think till the time
white didn't press clock and he still can takeback his move but
ofcourse have to move with same piece

[MikeB]

White claimed he won since the position is a won position for white and he was able to demonstrate that with Gaviota tablebases ;>) , which were loaded on the TD laptop.

Six piece Gaviota tablebases?

Anyway, the flag fell, so white loses the game.

Don't take me literally, the little wink meant I was joking.

I would agree, but that's not what the FIDE rules says or follows.

I do not know the USCF rules but it is a win for black even if black need to be able to get a forced mate in 4 by a possible series of legal moves because you can get the following position by a series of legal moves.
[d]K7/3n4/2k5/8/8/8/8/5n1N b - - 0 1
