Low level conventional call
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). Normally, the partner of the doubler must bid his best suit but may pass if (a) his right hand opponent intervenes or (b) on the more rare occasions when his hand is such that he wishes to convert the takeout double to a .

1) This hand is a minimal takeout double when the opponent opens 1. With other opening bids, it should be passed. Also, if the opening bid was 3, the hand would be not strong enough to double.2) If opponents have bid 1 – 1, the takeout double shows the unbid suits (spades and clubs)3) With 16 balanced points, this hand is more suitable for a 1NT overcall over any opening bid rather than for a takeout double.4) With 17 points and an excellent spade suit, this hand should double RHO's opening bid in any of clubs, diamonds or hearts rather than overcall in spades. Whatever partner bids, a subsequent bid of spades will indicate a stronger hand than a simple overcall.5) Over an opening bid of 1 this hand can double or overcall 2 depending on style and agreements. However, over an opening bid of 1, it should pass, expecting to double the opponents' subsequent heart or notrump bids for penalties.
