Looking for a guinea pig...

I want to test something in the threefold repetition draw thingy.

Anybody interested, plaese challenge me for an unrated game.

We will play:

1 Nf3 Nc6

2 Ng1 Nb8

3 Nf3 Nc6

4 Ng1 Nb8

5 Now White FIRST offers a draw, and then plays Nf3.

I'd like to see if the second player has the option to decline.

waiting with bated breath. 

Ooohhh exciting

Right, the game is on. I hust wonder whether get-lost is gonna take the full 3 days for every move.....

hope not, i'll turn blue. so, how are you going to take a screen cap of yourself showing you clicking the "draw" button.  do you have all the required mirrors and light sources.

Nope, I can claim a draw. Did you offer a draw before you made the move, get_lost?

OK, but this is not really right.

In this case, I should not have the option of playing on. You wanted the draw, the position was repeated, no way should I be allowed to decline.

Well, OTB this is what will happen:

You will call the arbiter, and tell him you intend to repeat the position for the 3rd time, and you want a draw.

You will then play the move that repeats the position, and it's a draw, yopur opponent cannot decline.

correct me if i am wrong:

FIDE - player moves, does not punch clock, then offers/claims draw

here - player moves, offers draw and punches clock at the same time?

perhaps there is a 1/2 turn something or other that makes it wonky. 

for the second test - instead of black claiming the draw black should try to ignore the draw button and move. 

That's what I did, I moved.

And I had the option to claim draw (rightfully, because the position was repeated) but not to accept draw.

But White should also have the opportunity to claim the draw, even before me.

thoeretically it should either not allow black to move or should give white a claim draw after blacks move. 

OK, so not only do you get Accept Draw and No Draw at the top, you also get claim draw at the bottom.

Hmmm, I think the point is Black should have no say.

It's a draw....

Clearly, it is Black to move, and he can claim a draw (repeat position)

Clearly, White reached that position first, and should be the first to be able to claim, but as you can see from the chat, there is no claim draw button after move 5, (because a draw was offered before move 5 was made?)

Somehow, the status of White's action should change from Offer Draw to Claim Draw in these situations.

so what happened when black tried to ignore the draw?

Oh, you can play on. I resigned the 2nd game after he played his move.

hmmm, well that does seem to be a problem.  only other question is if there was a claim draw flag for white after black's move.  but either way, this should be a lot clearer, apparently. 

Did you try to move first and see if the "Claim Draw" option came up, rather than offering a draw before the move. Maybe that is the disconnect.

And if is doesn't change or give the claim draw option then the evaluation code for three-fold probably only kicks in after the move is submitted, which would be an incorrect way to do it but understandable from a programming perspective.

Can you play the 6th move (3rd repetition) and immediately claim a draw?

I suppose with conditional moves set this may not work.

If you've repeated 3 times in the past, are you able to claim a draw 1, 2, 3, etc moves later?  Or immediately after the repetition is broken you can no longer claim.

If when the repetition breaks, the claim is no longer there, I agree that chess.com should implement a claim draw button that you can use along with the move which will create the 3rd repetition.

If you can claim at draw at any time after a 3rd repetition, that doesn't seem correct either.
