We got off to a good start. "I wish you hadn't come" joked an opponent on the first table. On the first board, defending 3NT, Anna lead the ♠4 and dummy came down. I sat East.
I took the A♠, and played the Q♠. Declarer was forced to play the ♠J from hand and Anna followed with the ♠2. I now knew for certain that we had three more Spades to cash, and the contract was going down. So what did I do? I cashed the Ace of Diamonds, then gave Anna her Spades. That was my highlight, on the very first board.
Later, concentration flagged a little. I was sitting North, and struggled with the extra responsibility of working the BridgeMate, and being in charge of all the boards. At least, when I accidentally brought out Board 13 for the second time, I was the first to notice I had the same cards.
Here's my lowlight:
What an exciting auction! East opened 1♥. Anna weighed in with 4♠, at unfavourable vulnerability. But did she realise it was unfavourable vulnerability? I had a pretty nice hand in North, but didn't really know what to do. I shuffled around a bit, then passed. When it got back round to East, she also shuffled around a bit, then came up with 5♥. Looking at all four hands, bidding 5♥ looks a bit mad. If she was going to bid again, why not bid 5♣?
I decided I couldn't let 5♥ go, so doubled it. This was very foolish. As Anna pointed out to me later, it's likely everyone's got a very distributional hand and my two Aces and a King don't mean much. West could have let 5♥x go, but decided to redouble, with chunky Heart support.
I got a bit scared, and thought about escaping into 5♠. An extra reason for doing this is that now West has shown Heart support I can be pretty sure that partner is short in Hearts, so don't need to worry about my three Heart losers. But basically, I bid 5♠ because I got scared 5♥xx was going to make. West passed out 5♠, which seems a bit inconsistent - if you're not prepared to double 5♠ you shouldn't really redouble 5♥ (I've made that mistake many times, as Anna will tell you).
Anna made 12 tricks, losing one Spade only. 6♠ is an excellent contract, as it only fails if you are unlucky and have to lose a Spade and a Diamond. No way we're ever bidding it though.
Full results here (results are correct, but hand records are wrong).
Final note - we now have a new defence to the Multi Two Diamonds. It's this: double shows either a weak NT hand, or 20+ points. Let's see if Anna prefers this to the old defence, which was simply that double shows Diamonds.
