Responding after the opponent has overcalled 2 ♥
- Shifting at level 2 (2 ♠) promises 11 HCP ( or more) and 5 ♠ cards
- Shifting at level 3 (with NO jump) promises 11 HCP ( or more) and 6 cards in the named suit
- Jump shifts these are supporting bids : jump fit
- Spoutnik double promises at least 4 cards in the other major suit (♠) and 8 HCP
- 2 NT 11 HCP and at least 1 stopper in the overcalled suit..of course, it's better with 2 stoppers !
- 3 NT at least 12 HCP and 1 stopper in the overcalled suit, 2 would be even better !
- Supporting the opening minor suit denies 4 ♠ cards and the possibility of a NT contract
- Cue-bid promises a minimum of 12 HCP, without any possible natural bid.

NT responses
- A NT response promises at least a solid stopper in the overcalled suit and preferably 2 (K J 9 are better than Ace x x)
- With 11 HCP propose a NT game : 2 NT ( pay attention to the assessment of your hand, your honors locations, your suits lengths)
- Above 12 HCP go to game : 3 NT ( pay attention to your points)
