Having won matches 2 through 5 of a Sectional Swiss after a disasterous first match, you are now playing for the event against a good team. They have a 15 VP lead on you, so you need a near blitz to win the event.
Halfway through the match (things are going OK so far) you pick up:
Fortunately, my partner and I have a tool designed exactly for hands like this one. A 4NT response to a one bid asks for ACES ONLY. If you want to bid RKCB you must make a forcing raise before launching into Blackwood. So, I bid 4NT, intending to sign off in 5♥ if partner has zero aces, 6♥ if partner has one ace and 7NT if partner has 2 aces. Partner showed 2 aces, so I bid 7NT and claimed after the opening lead.
Everyone at the table thought that this hand was a clear push. NOT SO FAST! At the other table, the bidding started out as follows:
(2♦) - 2♠ - (4♦) - ?
Now the hand is a lot tougher. I never did find out exactly what happened after that other than the opponents wound up in 6♥ and we won a large swing.
The rest of the match went well, we got our blitz and won the event.
(P) - 1♠ - (P) - ?
