98 REBIDDING A SUİT

If opener hasn't raised responder's suit, responder can bid it again to show a six-card or longer suit.

After opener rebids 2NT to show a balanced hand, responder rebids the heart suit to show the extra length. Opener now knows there is an eight-card major-suit fit and takes the partnership to the best game contract.

After opener rebids 2 Hearts responder can simply rebid the club suit to show the extra length. There's no need to jump to game, since the 3 spades bid is forcing. This would give opener a chance to rebid the hearts with a five-card suit. On the actual hand, opener can bid game in notrump with a diamond stopper. Responder comfortably passes, having already described the hand.
