Splinter Bid
Huh? A Splinter Bid is a game force response in the opener's suit by a hand with a singleton or void. The reason is that sometimes the singleton will enable opener to explore Slam, knowing there's only one loser max in the splintered suit.
Situation: when a responder has an opening hand in support of a major suit opener and with a singleton, we bid as follows:.
N E S W 1ª P 4¨* . . . "North, I have an opening hand or better, a Spade fit and a stiff Diamond."
The South hand, bidding a splinter in support of a 1ª opener, could be:
ª KQxx or ª Axxx © Axx © KQxxx ¨x ¨ x § KJTxx § AJx North can simply bid game, cue bid Aces, explore with Blackwood or go directly to slam.
Strength: an opening hand or equivalent in support of opener's suit.
Usage; fairly common, although it only comes up once or twice a year.
