Other Advancer rebids

• Moderating bid after a reverse: The more economical of 2NT or the 4th suit.
• 1C-1S-2D-2H
• 1C-1H-2D-2S
• 1D-1S-2H-2NT
• 1C-1S-2H-2NT
• All other 4^th suit bids are forcing (to game if a reverse or at level 3, for 1 round otherwise) - either looking for a stopper or preparing a forcing raise in partner’s suit.
• All other 1/2/3NT: Not forcing
• New suit forcing after opener’s suit re-bid. Forcing to Game at level 3, for 1 round at level 2. The most economical new suit may not be natural at all! Opener gives priority to showing a 3-card fit in advancer’s first suit. For example:
• 1C-1H/S-2C-2D: Round forcing, may not be natural
• 1C-1S-2C-2H: Round forcing, natural
• 1D-1S-2D-2H: Round forcing, may not be natural
• 1H-1NT(5+ spades)-2H-3C: Game forcing, may not be natural
• 1H-1NT(5+ spades)-2H-3D: Game forcing, natural
• 1D-1H/S-2D-3C: Game forcing, natural
• 1C-1D-2C-2H/S: Game forcing, natural
• Jump to new suit at level 3 after opener’s suit re-bid: 5+5+, non forcing. These are the possibilities:
• 1C-1S-2C-3D/H
• 1D-1S-2D-3H
• 1C-1H-2C-3D
• Return to opener’s suit (except 2C/D) after a NT re-bid by opener: Forcing if after 2/1, Limit otherwise. For example:
• 1m-1M-1NT-3m: Limit, 5+5+
  
• 1S-2C-2NT-3S: Forcing
• Jump to advancer’s suit at level 3: 6+ suit, non-forcing. In order to force the game with a 6+ suit the advancer must transit via 4SF, Check-back or “New suit forcing after opener’s suit re-bid”. For example:
• 1C-1S-2C-3S
• 1D-1H-1NT-3H
• 1C-1D-1H/S-2H/S: Forcing (Walsh)
• 1H-1NT(5+ spades)-3D-3H: Moderating (because 4^th suit is above 3NT)
• All other raises or preferences (simple or double) of opener’s suit: Forcing if after 2/1, Limit otherwise. For example:
• 1C-1H-1S-2/3S: Limit
• 1H-2C-2D-3D: Forcing
• 1C-1D-2C-3C: Limit
• 1D-2C-2H-3D: Forcing
• 1C-1S-2H-3C: Forcing (2NT would be moderating)
• Double jump to a new suit: Splinter, fit in opener’s (usually second) suit
