I played a game recently and was trying to save the draw. At one point we repeated a position for the third time and the "Claim Draw" option came up, but before I could click on it my opponent made their move and the option disappeared. In the end my opponent blundered and lost, so it didn't cost me anything.
Is this how it's supposed to work, and what should happen in a real OTB game?
