Responses to overcalls in a suit (without fit)

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.

WITHOUT a fit and WITHOUT a stopper in the opener's suit
  • With less than 7-8HCP: PASS
  • At the one level with at least 4 strong cards and a minimum of 8HCP: change of suit forcing
  • With at least 6 cards and between 8 and 12HCP: change suits 2 over 1. This is non forcing.
  • Without a strong suit to bid and with 10 or so HCP: cue bid the opener which makes the sequence forcing. This bid doesn't promise a fit with your Partner, nor a stopper in the opener's suit (an investigating bid).
