西家首攻S6。显然定约做成机会非常大，但你能确保定约吗？准备怎么打？ | i****e
发帖数: 642 | 2 Interesting hand! The 100% line is to win in hand, and play DQ!
In case D is 4-0 or 0-4 and DQ wins (good defense), switch to CK for 3S+2H+
1D+3C.

发帖数: 2804 | 3 Good thinking. The contract is in jeopardy only if diamonds break 4-0, even
then when you play DQ, the defender has to duck, so you can switch to clubs.
But there is still a tiny problem. Say you play CK, they win CA and shift to
a heart, what do you do next?

发帖数: 2168 | 5 You mean there would be entry problem to cash the 3rd spade?
So maybe play CK first, and see which suit defense returns?
If H is returned, then we cash SK before playing DQ;
if S is returned, no entry problem so we can just play DQ and then go back
to C.
even
clubs.
