发帖数: 2804 | 3 Claim down 1不肯吧，起码可以把赢墩拔一下，也许有人红心双张Ｑｘ，或是方块单张
Ｋ／Ｊ等。这牌机会还是不错的，怎么能认宕呢？能不能打成是方法问题，打或不打是
态度问题。。。

发帖数: 679 | 5 我试一下。已有9墩，只需发展1墩。先清将；拔H AK; 再C出手。若opp继续出C，则手
上垫H，逼opp再出牌。opp 无论出什么，你总能发展1墩：C或者D,明显；H,若西家出的
，则明手J或者第4张变大；若西家出的，是Q则将，是小则垫D，明手J或者第4张伊兰变
大。 | b***y

１）定约仍然１００％安全吗？
２）你准备怎么打？

发帖数: 679 | 7 I don't think 4s is cold anymore. Given E x-Qxxx-xxx-AKxxx W xx-xx-KQxx-
xxxxx, declare might not make it. When E wins C, he can play a D through,
and W can safely exit in C. If declare ducks the 2nd C, E can play another D

发帖数: 679 | 9 I am sure there is a better line out there. But I would play as follows.
Draw trumps (keeping trump K); Cash H AK; exit C;
- if W wins, the contract becomes cold (at best W plays another C, S then
discards H; W canot avoid being endplayed when E switches to D).
- if E wins, E has to switch to D (if C, S discards H, W canot avoid being
endplayed); assuming W wins and switches back to C; if E has CK, declarer
ruffs and plays H. Now if H is 3-3 or Q in W hand, declarer can still get
the 10th trick (trump K as entry). | b***y
发帖数: 2804 | 10 No, your line was optimal. :-)
Just one thing to add: even if East has Qxxx, you can still fall back on D
finesse. The contract is not cold, but it takes a minor miracle to beat it.
