nbxkh Posted September 7, 2013 Report Share Posted September 7, 2013 北除了加倍，没有其他选择。南叫3d，北再扣3h，南再叫4d，最后全pass。43配的4阶方块，是一般的分寸。运气好，还能mk。 Quote Link to comment Share on other sites More sharing options...

nbxkh Posted September 8, 2013 Report Share Posted September 8, 2013 P 2H X P2NT P 3H P3NT AP首先要明确，同伴加倍后，根据叫牌的规范，叫2nt需要多少的点力？ Quote Link to comment Share on other sites More sharing options...
HeartA Posted September 9, 2013 Report Share Posted September 9, 2013 这副牌，西开叫2H后，南北很难停在安全的定约。如果南北使用lebensohl：(2H) - X - pass - 2Npass - 3H - pass - 4C/Dpass - 5C - ppp 或者(2H) - X - pass - 2Npass - 4C - ppp 如果不使用了lebensohl:(2H) - X - pass - 3Dpass - 4C - ppp Quote Link to comment Share on other sites More sharing options...
