abstract:In the card game contract bridge, a takeout double is a low-level conventional call of "Double" over an opponent's bid as a request for partner to bid his best of the unbid suits. The most common takeout double is after an opponent's opening bid of one of a suit where the double shows a hand with opening values, support for all three unbid suits (at least three cards in each) and shortness in the suit doubled (preferably, no more than two).
However, a slight error with his final stone allowed Edin a double take-out opportunity, which he converted to force the British skip to take one and send the game into an extra end.
