nbxkh Posted March 17, 2014 Report Share Posted March 17, 2014 s5恐怕不是长四吧，若是长四，则根据11法则，没有牌大于5，这个概率不高。如果这样，下什么大牌都无所谓。当然，为了让同伴明确持牌，下s9最佳。假设是3张助攻，大约的分布是5332，由于南家没有进手，设想庄家是qxx的可能性比较高。先跟s9，逼出sq（若不出则第三手击落）。北家的第三手黑桃，可兑现赢敦。根据叫过程和明手的牌得知，北家拥有接近10点的牌力，两个进手概率很大。 Quote Link to comment Share on other sites More sharing options...
dvd Posted March 18, 2014 Report Share Posted March 18, 2014 总是选择上个9吧。 Quote Link to comment Share on other sites More sharing options...
nbtianyi Posted March 25, 2014 Report Share Posted March 25, 2014 一定是上S9 Quote Link to comment Share on other sites More sharing options...
nbtianyi Posted March 25, 2014 Report Share Posted March 25, 2014 有3467Q不见。长四带Q攻，下S9无碍。三张带Q攻，下S9无碍。三张无Q攻必下S9留桥。这手牌要防宕，必须拿到三墩S否则看明手的牌无宕机会。 Quote Link to comment Share on other sites More sharing options...
nbtianyi Posted March 25, 2014 Report Share Posted March 25, 2014 长四攻5必有SQ Quote Link to comment Share on other sites More sharing options...
