Responses to 2 opener

• 2 promises a king or an ace and is Game forcing.
• 2 denies a king or an ace but does not deny points.
• 2 shows at least a 5 card suit with 2 of the top 3
• 2NT shows at least a 5 card suit with 2 of the top 3 hearts.
• 3/3 shows 2 of the top 3 but these should tend to be 6 card suits

Responders rebids

If responder's first bid was 2 the only bid he can pass is 2NT. Some play that responder can show a real bust over any suit bid by opener by making the cheapest 3 level bid. Interference If your partner opens 2 and your RHO bids then a pass by you promises a king or an ace and a double denies a king or ace. If your RHO doubles then a redouble by you denies a king or ace and a pass shows a king or an ace.
