1 denies 4 spades.

 6 NT by North.  Developers of Jack explain that 4NT after a transfer is qualitative with 16-17.  Without 16-17, Jack just 'improvised' and 'glitch will be fixed in future.  It turns out that the championship now depends on making 6NT.

After running 5 spades, South led a low club at trick 6 and West played the 9 from ♣ Q 10 9 5 (having discarded the 3).  Declarer won the ace and ducked a club revealing the winning finesse against West, and +1440.  If West had played the ♣ 5 at trick 6 declarer would likely have gone wrong

14 IMPs for Jack
