Chapter 03
2/1 System
- Responder
- Bypassing 1S: can bypass 4-card S to set GF (1S then 4SF promises 5)
- 2D 5+: Alert 1M-2C, could be short (2+)
- Opener
- 2M promises 6
- Jump rebid sets: sets suit, max 1 loser opposite void
- Jump shift splinter: splinter for responder
- Shape Bid: Third bid by opener below 3M shows shape
- 5422 after M support: after 2-level support, even 2NT w/o stoppers 5422, opener 4M is worst 5422
- Major suit slams
- Splinters: with known 9-card fit
- Fast Arrival: denies 2 w/Q or better (responder denies 14+ HCP)
- Non-Serious 3NT: GF auction, Major fit, at or above 3M ... demands control bid. Otherwise control above 3NT is serious. Must show 3S control bid if possible whether serious or not.
- Scrambling for a fit
- Game before slam: Major fit, 3NT, 7-card Major, 5m
- 3NT: With no fit bids below 3NT are about 3NT
- Responder 2NT vs 4th suit (alert): has stopper in 4th suit Vs temporizing with 4th suit (could be short, concerned about stopper)
- Openers 3rd suit bid: Is shape or most natural bid without alternatives
- Opener 18-19: If Opener has 18-19 with 2NT second bid, should bid on (4NT/3NT)
- 3NT Jump 16-17: No fast arrival in NT, jumps to 3NT are 16-17 (by both)
- Impossible 4-bid: must be control for last suit (1S-2C-2H-2N-3H-4C)
