Cue-bidding the overcalled suit in response to the opening
In response to a major opening
A cue-bid shows 11 HCP and above with a strong support : too strong for a raise, and no singleton or void (else the response could be a Splinter).
In response to a minor pening
A cue-bid is a proposal for a NT contract, asking the opener to bid it if he has a stopper in the overcalled suit
Jump cue-bid after an overcall, in response to a major or a minor opening
After an overcall, Splinter can no longer be bid. Using a jump cue-bid in the opponent's suit gives your partner the same information ... when your short suit is the overcalled one, of course.
- A major 4th
- A good ♣ stopper
