这是正在BBO转播的White House Juniors 2015- SF 1/3---2015年白宫青少年杯赛上的一副牌面。
南北:以色列
东西:瑞典



问题来了,东家持有3张支持,2个Ace -- 这时候是积极加叫邀请还是保守地pass?
(近期会把原牌面一并刊出)

4333本来是最差的牌型,所以东选择了pass1n。
但是这手牌的估值,在2d-2h后发生了明显的变化,首先我们找到了53配合的高花;其次,自己在黑色花色上还有2A;另外,4张小d也变得可爱起来(同伴在d上面有废点的可能降低);
所以,足够3h邀请进局了,pass不能考虑。

4333--死牌型就是死牌型,4333面对5332,两个均型牌面,大牌分布一定很分散,那么即使是定约三阶也是下一的,即便是定约3nt也是宕的。说实在的,明手2个Ace+3个10,要说不动心那是假话。

邀请下3h 问题不大,4333牌,2个a ,3支持,4张小d ,希望pd d 没点并且高限,能够吃掉s的点力。

4h 没道理。

想告诉大家什么信息呢?有局冲局,无局止步?还是谨记这种牌再遇时干万隐忍?但万一开叫人高限D上无点是必丟局?
