The rule is once a a draw offer has been made, it cannot be withdrawn. You can then accept or decline. If you accept, it is a draw. The player should not be able to change his mind about a draw until after you make a decision to accept the draw or decline by making a move.
A claim of a draw first counts as an offer of a draw, and the opponent may accept the draw without the arbiter examining the claim. Once a claim or draw offer has been made, it cannot be withdrawn. If the claim is verified or the draw offer accepted, the game is over. Otherwise, the offer or claim is nullified and the game continues; the draw offer is no longer in effect.
In an ongoing game I was offered a "Draw". I was made aware of that by way of an e-mail rather than being on the game at that time. When I clicked the "Go to the game" link in that e-mail and was brought to the game I did not see any way to accept the draw offer. I then clicked on the "Offer Draw" link at the game thinking that there was a glitch in the system.
The person who had originally offered the draw now declined my offer.
I was confused at that point and asked the person what was going on. He stated that he had changed his mind about his draw offer and wanted to continue play.
My question is: Is there a rule or protocol governing a situation like this.
Thanks.
