3NT: 9-12, 1 good stopper

Suit: Good 5c+, probable game

Cuebid: Strong takeout

After a POSITIVE suit response,

this is ACE ASKING BID (AAB)

3rd step: Singleton or K (2nd round control)

5th step: AK or AQ (1st and 2nd round control)

Opener can then rebid the suit to find out if control is honor or

ruffing. (Goren omits this, but it was in original precision and is

included in other versions.) The replies are:

1st step: ruffing

2nd step: honor

TAB and CAB after intervening bid by opponents:
