Offering a draw when you're clearly losing the game...

It's a good idea in theory, but it could be easily abused. I would say maybe this is implemented after one side offers 3 draws. If their opponent offers a draw they get one back, but their opponent-if they haven't offered one-remains at their 3 draws, and cannot earn any until they offer 3. You could also have the amount of draws, and the way they are determined be based off of ELO range.

How can it be abused? Think.

You offer a draw. The opponent declines. Your draw button is turned off.

Your opponent now can offer a draw.

And back and forth and so on.

And if your opponent doesn't accept or decline in a clearly drawed/losing position? Wastes your time. Unless there is a limit on how long you can wait to accept/decline it before the offer goes away.

Clock time is independent of draw offer.

Now I have to explain but I shouldn't.

You moved and offer a draw. Your opponent's time runs down.

You didn't move and offer a draw, you clock is running down.

Also self explanatory. If your opponent moves, the draw offer is obviously declined.

Just like old school face-to-face chess.

A draw offer does not stop the clock.

That's not what I'm saying. I'm saying does the draw offer last for a certain amount of time before it can no longer be accepted?

It lasts until your opponent makes his move.

Why do I have to explain something so obvious, twice.
