2nt 3C = RELAY to find a 4+M at least to show small SI . Can be 6-4 majors or 5S-4H 3D = 5+H , can contain 5H-5S but then is SI 3H = 5+S , can contain 5S-5H but then is weak 3S = both minors, or 6+m SI 3nt = Natural 4C = 6+H at least small SI 4D = 6+S at least small SI
2nt 3C 3D = Denies 5M and 4S 3H = 4S but can have 4H 3S = 5S 3nt = 5H
2nt 3C 3D 3H = Responder wants to play 3nt or has at least small SI : opener bids nearly always 3nt or bids 3S with a MAX 3S = 4H 3nt = No 4H 4C = 4+C SI 4D = 4+D SI 4H = 5+S-4H SI 4S = 6S-4H I play it , limited strength 3nt = 5S-4H not SI therefore limited strength 4m = 4S-5+m 4H = 6H-4S I play it , limited strength
2nt 3C 3D 3H 3x 4m = 4+m SI 4D = 4+D and 3+C 4H= 3C 4S = 5om 4nt= No FIT and MIN 5m = 4m weak cards 5x = 4+m RKCB In this system in order to show a FIT in a minor we play all the time that responder bids a 4+m with values for Slam 4H = 6H-4S SI 4S = 6H-4S Quite strong, slam practically certain
2nt 3C 3H 3S = Looking for 4H with opener , but not promising H . Opener bids 3nt without 4H and 4m with 4H-4S-3m . After 3nt responder can continue: 4m = 4+m SI . After 4m by opener, which shows the H, 4H wants to play 4H and 4nt is RKCB while 4S wants to play 4nt which shows SI without a FIT
2nt 3C 3S 3nt = SO 4m = 5+m SI 4H = 3+S SI 4S = SO
2nt 3C 3nt 4C = 3+H SI 4D = TEXAS for 4H 4H = 5C SI 4S = 5D SI
