Slow and Fast paths
2NT : Slow path, requests puppet bid of 3C from partner
1NT – (2S) – 2NT – (P) – 3C
2NT bidder passes or rebids suit at 3 level.
3 level bid is invitational Cue bid indicates values for 3NT, stopper in opponents suit and interest in unbid majors 3NT indicates stopper and no major interest
Direct bid at 3 level: Fast path
Direct bid in a suit is a transfer bid Bid can be weak or strong. If weak, bidder will pass partners acceptance If transfer is into opponents suit, bidder has values for 3NT, does not have stopper and has interest in unbid majors Direct bid of 3NT is strong but no stopper.
