The replies without a fit in the partner's suit
Your Partner who has just overcalled can have between 8 and 17HCP (with more than 18HCP he would have doubled).The principles:
- Changes of suit at the one level are forcing
- 2 over 1 are non forcing
- 2 over 2 are forcing
A cue bid is often used to show strength and makes the sequence forcing.
If the player in 3rd seat bids,
no bid is forcing unless made with a jump.
