I am playing an online game and we have reached a dead draw position (opposite colored bishops). I've offered a draw but my opponent insists to continue to play. Since this is an online game, it will last forever.... Is there any way I could claim a draw in this situation?

good luck!

I guess there is a way to submit the position to the staff to judge it

The same is true of fortresses.  Unfortunately, without adjudication (which is admittedly quite labour intensive), the only recourse at the moment is to wait out the 50 move rule and claim your draw.

The people who insist on playing on in dead drawn positions in correspondence are a real nuisance.

"nuisance" is such a genteel term in this case!

you should just sacrifice your bishop and if he takes it it will be a draw and you can make a draw by the 50 moves rule.

Not a bad suggestion in this case, actually.

I don't believe that we are supposed to give advice, even if it's a position where  a donkey would agree on a draw. 

Yeah, technically, you're right.

Place your king in the corner of opposite colour to his bishop, and place your bishop in a far corner and just move it on the 2 squares, say g8  to h7 and see what he does, keep it going for years if necessary, and always wait until the last minute before moving, should drive him crazy

Then if his king approaches your bishop, run it over to the opposite corner and do it again !

 Actually, if it is  "K+B vs K"  ending, the position is automatically drawn. (no need to wait for 50-move rule: just press "offer draw" button.  This is according to the Chess.com Help file I read here)

 Getting back to the main question (the issue posted here), the critical point is this:  Is the position truly "dead draw" as BigAlex posted?   That is, is it a K+B vs K+B (same color or opposite colors make no difference)

 Do not forget that "Book draw" has no meaning in FIDE Laws of Chess, or anywhere else for that matter. Even many GMs lost "book draw" positions, or won "book lost" positions, you know.

If you're referring to my post a couple days ago, the position being asked about was the exact position of the game at that time. The game has moved on since I posted the link.

I saw this thread earlier and debated with myself whether it would be ethical to post advice. I couldn't decide if this question and position were generic enough so I figured I'd just leave it alone.

I've lost an endgame that was opposite coloured bishops. GMs have lost them too. Not all opposite coloured bishop endgames are drawn, so there would be no way to make it an automated process. Playing out the ending may take quite a lot of effort to make sure it is really drawn. If it's one of those positions where no progress can be made, but your opponent plays on - you have my sympathy.

@ BigAlex

If he won't take a draw then you must play for the win.

Yeah, most probably. What you have on your side is, since the opponent declined a draw, you know that he will likely be trying to force a win. He might just make a mistake there, but you have to be patient and wait for it.

Just by having opposite color bishop does not make it a draw. What if you have a bad bishop and he has a good bishop. Maybe you can't the possibiblities of a win and he can?

Well, I´ll play on and see what it happens. Now his vacation mode turned on lol

I have the good Bishop and he has the bad one. Anyway for me it´s a sterile position. Let´s see what happens. I can even lose!
