This first hand, partner opens an intermediate 2 bid, showing 9-14 HCP, and 6+ hearts. You bid a natural and forcing 2♠, and partner rebids 2N to show a hand with at best Jx of spades. 3♦ is natural and forcing, and 3♠ probably shows a small doubleton spade. 4N is keycard, and 5♣ shows 1, with the redouble showing first round control of clubs. If you bid 5N now, partner will give you specific kings. Alternatively, you can bid 6♦, which ostensibly asks for a 3rd round diamond control, though there is a small but very real chance partner will assume that you are making an offer to play and pass.
Do you explore for grand, bid grand, or settle for small slam here? Are there any previous calls that you particularly despise?

How would you go about exploring this hand? Any strong feelings about whether this hand should have been opened first seat? Partner's 2C bid could be a 20-21 balanced hand, a 24+ HCP balanced hand, or any unbalanced hand that would normally open 2C in 2/1 style bidding.

This was the most spectacular hand of the match, obviously. Your bid.
