Bidding went: (opps passing throughout)
P-2♣,
2♠-3♦,
3N-4♣,
4♦-4♥,
4♠-7♦
2♠ showed a positive response with 2/3 top honors. I thought 4♣ was a cue-bid, and then thought that my partner thought it a second suit and was setting preference to ♦. When I cue 4♥, partner cued 4♠, and off I went.
Off one on the ace of spades lead. Partner took 4♣ for gerber, and decided to remind me that she had a good spade suit by cueing the KQ.
The other table the declarer got to 6 hearts (the right contract), which is unbeatable, except that he revoked. Push.
Though our team did not make it, I got added to the team that did, so I will see you guys in Vegas anyway.
