Contract:
6♠ by South
Lead:
♣2
With support for partner's major and game points, North uses a Delayed Game Raise by starting with 2♣. Opener knows partner has 10+ points and forces to game by jumping in diamonds. This shows five spades, four diamonds and 15+ points.
North has a flat hand but wants to show the extra points. When the bidding is game-forcing, jumping straight to game shows a minimum hand (for the bidding). Whereas, bidding slowly show extra values. 3♠ shows support and extra values beyond the 10 shown so far.
As South also has extra values, RKCB is used to look for a slam. When partner shows two key cards, South knows they are the missing aces. At this point it is still possible that partner has no kings and that a slam cannot be made, but with such a strong hand most South's will ignore that possibility and treat 6♠ as the minimum contract. Given that North's hand has not even yet been limited, South will bid 5NT looking for kings. North has only one and the pair settle in 6♠.
