Your partner has opened with one of a major. You have at least four-card support, game values and a singleton. You are just about to make a splinter bid, when your right-hand opponent overcalls in your singleton suit. What do you do now?
    Next, look at the North and South hands. You are in seven spades after West overcalled in clubs. West leads the heart king. How would you plan the play?
    A jump cue-bid is a splinter — you make a single jump in the overcaller's suit. In this deal, North does exactly that with his four-club response. Now South, who can visualize ruffing his low clubs on the board, control-bids (cue-bids) four diamonds to express some slam interest. After North shows his first-round heart control, South does the same in clubs. Then the partners show their red-suit second-round controls at the five-level before North jumps to seven spades, knowing South would not bid like this without the spade ace. Who said that all slams require Blackwood?
    You have to find the diamond queen, so set out on a voyage of discovery. After winning with dummy's heart ace, draw trumps in two rounds, cash your club ace, and crossruff, trumping three clubs on the board and three hearts in your hand. What have you learned?
    That West began with two spades, four hearts and six clubs. So he has precisely one diamond. The contract has become a certainty. Play a diamond to dummy's king, then run the diamond jack through East.
    Beautifully bid and played!
