My partner opened the bidding one heart in 2nd seat. I held this hand as responder:
I really like my hand. I want us to end up in at least four hearts. Partner may be able to bring home five spade tricks from dummy. I responded one spade. Partner’s rebid was two diamonds. My rebid was three clubs (4th suit forcing to game).
Partner next bid three diamonds, so I know that she is at least 5-5 in the red suits. I bid three hearts, setting hearts at the trump suit, and partner raised to four hearts.
This is where I went off the rails. I should not have been so anxious to use my new cue-bidding-to-slam tool. Too many warning signs: misfit in diamonds, no second-round control in clubs, none of the top four honors in hearts, no extras shown by partner in the auction.
Undeterred, I foolishly cue bid four spades, showing first round control. Of course, we got too high and missed our easy game. Sorry for falling in love with my hand, partner.
