把红花色的赢墩全拿光，哪怕都不是3-3分布也已经无关紧要了。第三墩草花不能先兑
现，以防西是7-1-1-4。

发帖数: 642 | 13 That is right.
I think cashing 4 kings plus CQ won't lose chance for other layout. Given
west holds 7 spades, it seems we can make 6NT 100%.

Q
Now we already know whether west has any 4+ cards in H D or C. If he doesn't
have any 4+ suit beside S, we cash all H D C winners, and endplay west in S
if needed.
If west has 4+ C, we cash two red Qs, and at 4-card ending, he will have
either SJTx Cx or SJT Cxx. For the former, we strip his C, and endplay him
with S. For latter, we set up a S.
If west has a 4+ red suit, we concede another red suit loser to east at the
above 6-card ending. Then we can always squeeze west in S and the red suit.

发帖数: 2804 | 18 嗯，再具体些。West follows suits with 4 kings, but pitches a spade on CQ.
Now what? If you cash both red aces, you find that west follows hearts, but
pitches another spade on DA.

发帖数: 642 | 21 Oh yeah. To cover that, it seems we can't cash all those AKs. We need to
cash a C first. If we find west has no C, we need to leave a C entry for
dummy. Then we cash red suits one by one gradually :) If west shows out at
red suit, we concede it to east. If west follows one C, we can cash all AKs
in H D C.

can't destroy our entry.

发帖数: 2804 | 24 嗯，这样比较面面俱到了。如果对所有情况加以综合优化的话，可以发现其实不需要动
梅花。第一墩黑桃吃住，然后兑现红心ＡＫ和方块ＡＫ。
如果西家红牌均跟出，则继续兑现ＨＱ和ＤＱ。西家如果任一红牌有四张，庄家就把另
一门红牌最后一张输给东家，之后可以对西家进行简单挤牌。如果西家两门红牌都只有
两张（７２２２牌型），庄家兑现梅花赢墩之后小黑桃投入西家。
如果西家某门红牌单缺，比方是红心，庄家就继续兑现ＤＱ，如果西家有至少四张方块
，庄家就打红心小牌给东家（不可先兑现ＨＱ），之后对西家挤牌。如果西家两门红牌
都不超过三张，则兑现三轮红心三轮方块两轮梅花，最后总可以黑桃投入西家，或是建
立一个黑桃赢墩。
这个牌要防止的一个误区是第一轮忍让以期“调整输张”。需要认识到，对东家的挤牌
是不成立的（东家两门红牌都坐在明手后面），但是庄家可以利用手里的黑桃９８对西
家实行终局投入。而如果确实需要对西家挤牌的话，可以后期用别的方式调整输张（在
另一门红牌输一墩给东家）。
