Contract:

6♥ by South

Lead:

♣2

1♠ – 2♥ shows 5+ hearts and 10+ points. North must force to game with 3♦. Despite South's extra points, there is no known fit, so she bids 4♥ thinking it will be the final bid. It shows a 7-card or very good 6-card suit.

North has slam ambitions despite the singleton trump, and uses RKCB to find partner with the three missing key cards. If partner also has ♥Q and ♦K, then a grand slam would be on, but they settle for 6♥. Note that the 5♠ bid must be interpreted as asking for the trump queen, because 4NT has already implicitly agreed hearts as trumps.
