NT jump rebid to show a third zone hand (in this case 19H) and a balanced distribution
NT jump rebid to show a third zone hand (in this case 19H) and a balanced distribution
Development after the opener's 2NT jump rebid
- With enough strength for game and a 5 card major, the responder will name the other minor (in a Roudi style !!)
- Supporting the opening minor is natural : simple or with a jump if slam is in the air...
- Repeating the major suit at level 3 shows 6 cards and a hope for slam
- If the responder jumps to game in his suit, it's a stop
- The responder's shift (in a major) shows a 2 suit hand (5-4 or 5-5) and is forcing.
