Q865 | i****e 发帖数: 642 | 2 First 3 tricks: S AKQ, discarding D AKQ from dummy;
C AK;
D to hand to set up DT, so we have 10 tricks;
If east wins DJ, we will squeeze west in 3 suits. If west gives up
S or C, he will be squeezed again; If west gives up H, we will
have enough tricks in H.
Even if east ducks D, west has to discard from
98

It won't help for him to give up S or C, since he will have to give
up another suit later. If he discards a H, we can duck a H to him.

up the contract?
That is far from double dummy lead :)

| m*****0 发帖数: 9 | 4 只有11墩吧?
庄家必须吃住首攻,然后没桥。
W能留住H,E能守住D.明手红牌2输墩一个也跑不了.庄手上2个D将先被剃掉。
比如庄兑现3个S,最后5张牌,明手HAK87+D3;W手上HQJT9+S9;E手上5张D.
如果庄兑现4个S,最后4张牌,明手HAK8+D3;W手上HQJT9;E手上4张D.
不过还是想看看lz的妙解.

so is the opening lead! :)

| p***r 发帖数: 20570 | 10 just pitch DAKQ under S AKQ, then unblock CAK, play D3 to DT. If East wins,
west will be squeezed in three suits. If east ducks, west pitches H, then
you duck a H to make it. If west pitches S or C, you just cash the winners
in that suit and try to squeeze him again in the other two suits.

本题的精髓在于,要敢于破釜沉舟。把AKQ垫在AKQ下面,原有11个赢墩,损失3个赢墩
,换回2个赢墩(D10和CQ)的同时,形成对西家三门挤牌的局势,再获得2个赢墩。是
一道复杂的加减题:11-3+2+2=12。
