Source: https://www.andrewrobson.co.uk 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. 1-1-2or 1-1-3. Dealer South N/S Vul

South’s jump rebid of 2was 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 4to 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 led5 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.
