Bridge Tip #30
by Mark Blumenthal on June 28th, 2009
There is such a thing called an action double. Assume you happened to opened three hearts hoiding this hand, 3, AQJ10875 7, K862, non vulnerable against vulnerable . LHO bids three spades. Your partner bids four hearts. It goes four spades to your right. Although the preempter is not supposed to bid after his initial call, you could now double. You probably have a trick on defense and more playing strength than you figured to have from made your initial bid . With good defense( such as one trump trick and an outside trick. ) your partner could leave it in or, save in five hearts if it seems your partnership has with little chance to beat the contract. These doubles are used in competitive auctions in which you are not sure whose hand it is. I would not use an action double unless I were playing with a partner I was sure would fully understood what I am doing.
