牌型的強度

www.gg.caltech.edu/~jeff/knr.cgi 可以幫你算。

6-4:
K&R (AQTxxx Kxxx xx x) = 13.65
K&R (AQ9xxx Kxxx xx x) = 13.10
K&R (AQxxxx KTxx xx x) = 13.00
K&R (AQxxxx Kxxx xx x) = 12.80
K&R (AJTxxx Kxxx xx x) = 12.30
K&R (ATxxxx Axxx xx x) = 12.30
K&R (Axxxxx ATxx xx x) = 12.20
K&R (Axxxxx Axxx xx x) = 12.00

5-5:
K&R (AJxxx Axxxx xx x) = 12.75
K&R (ATxxx Axxxx xx x) = 12.25
K&R (AJTxx Kxxxx xx x) = 12.00
K&R (Axxxx Axxxx xx x) = 12.00

5-4:
K&R (ATxxx AJTx xx xx) = 12.15
K&R (AJTxx Axxx xx xx) = 12.10
K&R (AJTxx KJTx xx xx) = 12.00
K&R (AJxxx AJxx xx xx) = 12.00

所以這些牌都應該正常開叫...
