2 Quantitative raises are on directly after Stayman or Jacoby transfers. If a suit is agreed, use RKCB instead. SImilarly, quanti-

tative raises apply after 2NT opening too.

3 ST TOMA S stands for Slayman Then The Other Major Asks Slam

4 First round controls are aces and voids

Minor Suit SIgn-off

Requirement: 6 card minor suit, unsuitable to play in no-trumps (unbalanced hand), 7 or less points

1NT - 2S - 3C for pass or correct

Pass - Sign-off in clubs

3D - Sign-off in diamonds

Alternatively, you may want to play four-way transfers instead of minor suit sign-offs. Please approach your seniors or

research yourself for this topic.

There can be three types of game tries: short suit game try, long suit game try and help suit game try. Our recommendation

is to use two-way game try, including help suit game try and long suit game try.

This is the scheme if New Minor Forcing is used. Alternatively, one can play Checkback Stayman or Puppet Checkback.


System Notes 13

8 After a New Minor Force, the priority is to show 4 card hearts, then to support partners major, and lastly is to bid no trump.
