the 50 move rule for stalemate

Sort:
SLOBess

is that the rule, 50 moves with no exchanges and it's a draw.  could be for the knight bishop mate or the queen vs rook mate, ya?

not quite......no exchanges and no pawn moves.

that said, some tournaments ( or maybe international events) may expand the 50 move limit for certain positions, ie; R + B  versus R

There is also a 75-move rule, adopted by FIDE in 2014. Rule 9.6b states that if 75 consecutive moves have been made without movement of any pawn or any capture, the game is drawn unless the last move was checkmate. The difference is that a 50-move draw has to be claimed, but the 75-move draw is automatic.

Automatic because of an electronic board I presume.

n9531l

Automatic because of the presence of an arbiter.

Regarding your stalemate comment, it's true this thread has a poor title, but the initial post clarified the question.

The official rules of both FIDE and USCF state that draws by 50-move rule or triple occurrence of position don't occur unless correctly claimed by a player. I'm sure there are sites that support non-standard rules, which in some cases may even be a good thing.

Where I play chess there is an automatic draw when there are no captures and no pawn moves in 50 moves. I don't think this place has that feature so the chess players have to count the moves which is ridiculous.

 

That's why you have a scoresheet. It's easy enough to notice that the last capture was move 72 and do a little arithmetic: 72 + 50. The rules presume no less.

 

I avoid sites that improperly implement the rules.

Also where I play chess I have an option to have their software automatically call it a draw if the position repeats 3 times. I doubt this place has this.

See my "About Me" to help you understand.

You have to claim the draw (same as when you play irl). The draw button changes to "Claim draw" so you don't have to count moves.

Automaticities were introduced in 2013 or 2014 to facilitate computer chess. Apparently the programmers wanted some control over terminating games though it is unclear (to me) why this was necessary. The automatic margins are a bit bigger than the claim margins to allow the contestants to play the psychological 'chicken' game.

In retrograde chess, automaticities are decades older and they effectively replace claim draws even though the debates about them are as old as the automaticity 'rules' themselves. In the absence of arbiters and actual players and the presence of all kinds of unusual stipulations (goals), problemists have ample reason to invite external objective arbitration on game termination. An example of confusion caused by 'claiming': If the assigment is to draw in 5 moves, would you count in or out the move that is claimed to make the draw but is never executed on the board?
