Your partner bids One Spade, and the next player passes. Both sides are vulnerable, and you have a partscore of 40. What would you bid with each of the following five hands? 1. Three spades. With 40 on, a direct jump-raise indicates a hand of opening-bid proportions and a fit for partner’s suit. The purpose of the jump-raise is to alert partner to the possibility of a slam. Partner does not have to bid again. He continues forward with values that justify exploring for slam opposite responder’s announced strength.
2. Three hearts. The jump-shift guarantees 17 or more points and forces opener to bid again (with a 40 partscore, partner would not have to answer a two-heart response). Opener rebids naturally depending on both distribution and high-card strength. A three-spade bid by opener would show a rebiddable suit, while three notrump would indicate a balanced hand and lack of interest in slam.
3. Two clubs. Since a contract that would yield game has not yet been reached, opener must bid again. It’s best to mention the club suit first, planning to show your good spade support next should opener be interested in slam. If the partscore were 60, clubs would not be mentioned; in that case, a direct raise to three spades would be the better bid.
4. Two spades. You have good spade support and are in the range for a single raise, so that is the best action. Two hearts (not forcing) would be an inaccurate response, as that bid would normally show a good heart suit and imply lack of support for spades. If partner bids again over two spades, trying for slam, you can then mention your heart suit, at the same time indicating slam interest.
5. Three notrump. Since two notrump would be sufficient for game, three notrump is a slam try, but opener is not required to bid again. If he has a minimum opening suitable for notrump play, he can pass.
The three-notrump response with a partscore of 40 has the same meaning as the same bid without a partscore. It indicates notrump distribution, 16 or 17 high-card points, and stoppers in the unbid suits.
