Everyone will open 1D with the South hand which is unbalanced and easily meets Rule of 20 (13+6+3). North has a nice 16 and can make a game forcing jump-shift of 2H, though the suit is marginal. But the jump-shift always shows a really useful suit. South jumps to 4C: the sequence was already forcing, so the jump is unnecessary: it is a SPLINTER showing a singleton or void and agreeing hearts as trumps. North cue bids the Ace of Diamonds and South, with nothing extra, signs off in 4H. But with the lovely controls, North is worth one more try and asks for controls with 4NT Roman Key Card Blackwood. South shows one, an Ace or the King of trumps. Just one control is missing, so North chooses 6H.
