Lead CK

西连拿CAK,然后东以H7将吃第三墩C,第四轮东家出SK。
当东家持有DQXX时,是一种形式的单紧逼-将牌紧逼。请尝试一下。

根据叫牌,东家应有6张,加上2张、1张,最多有4张,西家则最少3张;如果Q在西家,则没有任何机会,只有寄望于Q在东家,东家开叫2,持有8P应在情理之中。如此,对东家在上挤牌就相当于做四明手题了。南家A进手后,连打4轮将牌,成如下局势:

南家再出将,北家垫4,东家则受挤。东家若垫,则北家A进手,将吃1轮K再进手兑现赢张;东家若垫,连打即可。唯一出现失败的情况是东家持有7张,牌型是7222,在东家最后保留2张、2张时采用上述将吃的路线,北家没能树立赢张,南家J也无法兑现,不过东家若持有如此牌型应该会开叫3s,所以失败几率很小。

dongfz打得好:南家再出将,北家垫♦4,东家则受挤。东家若垫♠,则北家♦A进手,将吃1轮♠,♦K再进手兑现♠赢张;东家若垫♦,连打♦即可。
后面的:唯一出现失败的情况是东家持有7张♠,牌型是7222,在东家最后保留2张♠、2张♦时采用上述将吃♠的路线,北家♠没能树立赢张,南家♦J也无法兑现,不过东家若持有如此牌型应该会开叫3s,所以失败几率很小。我没看见明白.
