(a) I thought the long spade suit and the JTs justified a rule-of-19 opening. You may disagree.

(b) Roman keycard Blackwood.

(c) Two keycards.

Partner put down the strongest dummy I've ever seen.

Any reasonable line of play works, 13 tricks were made at every table. All credit is due to my partner's bidding. He needed to know where the top two diamonds were, so he found out.

This is one of a few hands I've particularly enjoyed, listed here.
