South was dealer and the occasion was the club's weekly duplicate night.
South opened 1C not fancying 1NT with two doubletons. North replied 1S and South rebid 1NT.
North rebid 3H which was followed by South's 3NT showing no support for the majors and a desire
to settle for a reasonable looking game. North then bid 4C. South took this to be delayed support for clubs after
failing to find a major suit fit. South bid 5C and North carried on with 6NT. This failed as there was a 4-2 split in Diamonds and Spades. In the ensuing cat fight. North pointed out (at length) that South should have rebid 2C, not 1NT
and that 4C was asking not supporting as it was bid after a no trump bid.
