Some bids in bridge are complete “sign off’s” - e.g. 1NT-2♠. Some are invitational - e.g. 1♥-3♥, and some force partner to speak again - e.g. 1♣-1♦. A few bids actually force partner to keep bidding until Game is reached; one such “Game-forcing” sequence is a jump rebid in a new suit by Opener - e.g. 1♣-1♦-2♥ or 1♥-1♠-3♦.

South’s jump rebid of 2♠ was game-forcing and showed at least five ♦s and at least four ♠s. North correctly gave “false preference” back to South’s first suit. South then bid 4♦ to see if his partner could cooperate in a Slam venture. North - still unable to pass as game had not been reached - made the weakest bid by raising to 5♦.
West led ♣5 to East’s ♣A and South trumped East’s ♣Q continuation. He crossed to dummy’s ♦10, cashed ♦Q and led ♠5 to ♠2, ♠J and West’s ♠K. West returned ♣K and South trumped, drew the last trump, led ♥Q overtaking with dummy’s ♥A, and led ♠9. East played ♠3, South ♠8 and West ♠6. ♠7 followed to ♠4 and South’s ♠10 won. The rest of his hand was high.
ANDREW’S TIP: A jump rebid in a new suit by Opener is forcing to Game.
