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

 

[hv=pc=n&e=sa62ht72dt963cat7&d=s&v=n&b=15&a=p1npp2d(%E8%87%AA%E7%84%B6%EF%BC%8C5%E5%BC%A0%2B)2h(5%E5%BC%A0)p?]133|200[/hv]

 

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。
