Codo Posted July 17, 2013 Report Share Posted July 17, 2013 1 ♣ 1♠3♠ 3 NT (nat, serious3NT)4 ♦ 4 ♥ (D control, no club control), club control)4 NT 5♠ (KC, 2+ Q) 5 NT 6♣ (K, Club K)6♥ 6 ♠ 6 hearts asks for 3 round control in hearts. I guess East will just bid 6 spades, he does not know that his 3. heart will go on the 4. club... Maybe, West is even strong enough for 4 ♠ over 1 ♠. In this case, East will surely gamble 7 ♠ after getting to know about the King of hearts and the missing King of Diamonds... Quote Link to comment Share on other sites More sharing options...
Fluffy Posted July 17, 2013 Report Share Posted July 17, 2013 upgrading west to spliner makes it a no brainer:1♣-1♠4♦-4NT5m-7♠ East counts 5♣, 5♠, 1♥, 2♦. If west only has 4 clubs it will be tough, but ♣J+♥K save the day or ♥KQ... worse I can think of is ♣J+♥Q which requires a finesse so grand must be a good bet.

Codo Posted July 17, 2013 Report Share Posted July 17, 2013 It is not an upgrade, but splintering aces? Quote Link to comment Share on other sites More sharing options...
tangjian Posted July 18, 2013 Report Share Posted July 18, 2013 1、1♣ 1♠后开叫方首先在要评估一下持牌的价值，在哪个区间，个人觉得高花有增值，低花有减值，无5张套，还在邀请的范围内。2、如果开叫方跳叫3♠的话，就属于高度限制性叫牌了，以后就没资格作为主控方发动满贯。1♣ 1♠3♠ 4♣4♦ 4nt5♦ 5nt6♥ 7♠通常跳叫3♠为非均型或5422点力集中的半均型，通过开叫方答出♥K和自己的♣的持牌情况可以看出开叫方为非均型5431或4441，单张DA，大满贯机会多多。 Quote Link to comment Share on other sites More sharing options...
