It has nothing to do with Stockfish deciding anything. SF is a software chess engine.
FIDE rules apply. A King + B is sufficient material to checkmate when the opposing side has material. It is only a draw vs. a lone King.
The chess interface recognizes mating material exists. Another thread today claims a K + N + N should be a draw vs. a lone King as it is impossible to mate. Not so. With perfect play the 2 knights can not force a mate, but it is not so difficult to checkmate against poor play.
You can give one thousand sources that it is draw but that‘s not relevant. The player has to show it. If he has no time left one must postulate that he can‘t. Everything else is unfair towards his opponent.
Just to be the devil's advocate here.. isn't there a rule that says something about drawing by "insufficient losing chances?"
@DrHack Tell your client: No.
So.. this little statement is in the fide rulebook. What does it mean?
"A player with less than two minutes remaining on the clock may claim a draw under Article G.5, even if there is a delay clock already in use for the game. The player may claim a draw based on the opponent not making any attempt to win the game by normal means. Article G.2 requires that it be announced before the start of an event whether appendix G applies to the event."
Here is g.5 so you don't have to look it up: G.5
G.5 If Article G.4 does not apply and the player having the move has less than two minutes left on his clock, he may claim a draw before his flag falls. He shall summon the arbiter and may stop the chessclock (see Article 6.12 b). He may claim on the basis that his opponent cannot win by normal means, and/or that his opponent has been making no effort to win by normal means
If the arbiter agrees that the opponent cannot win by normal means, or that the opponent has been making no effort to win the game by normal means, he shall declare the game drawn. Otherwise he shall postpone his decision or reject the claim.
If the arbiter postpones his decision, the opponent may be awarded two extra minutes and the game shall continue, if possible, in the presence of an arbiter. The arbiter shall declare the final result later in the game or as soon as possible after the flag of either player has fallen. He shall declare the game drawn if he agrees that the opponent of the player whose flag has fallen cannot win by normal means, or that he was not making sufficient attempts to win by normal means.
If the arbiter has rejected the claim, the opponent shall be awarded two extra minutes.
DrHack... the point you raise is a valid one ...
for OTB play when an arbiter is present.
This is online chess, no arbiters present to adjudicate games.
Also, are not the articles you cite apply to standard games and not blitz games, where a different set of rules apply?
easy, both players agree draw, if not the case, play till dead :-D
No. It is not that easy. Rules exist allowing draw claims. One player refuses a draw, the other player can make a draw claim under several rules. He does not have to "play till dead" if the conditions are met.
g5 only applies to games that do not have an increment... I would know because alot of our tournaments here in South Africa still play without increment or clocks sometimes :P
So the g5 rule only applies to that. That is why they say even if a clock is added with delay the g5 rule can be applied. Its basically there to prevent people from just flagging in obvioulsy drawn positions. Where if you had increment it would not be a problem.
But as it states the g5 rule must be announced at the start of the tournament to be in effect!
