We had only 4 boards remaining to rescue our ranking. I start to find way to generate some swings as an attempt to get our ranking up.
Board 11, sitting S:
It was expected that everyone would land in the same contract 4♥. We got lucky that the opponents didn't find the killing ♦ lead, and we scored a top as a result as the only table making 4♥. In reality 4 tables ended up at 4♥ and 1 ended up at 3NT, and the 3NT table ended up 3NT=.
Board 12, sitting S:
Once partner responded 2♠, I immediately expected the field would sit at 4♠, and I wanted to generate a swing by bidding a borderline slam. As we were not an established partnership, we hadn't even agreed on which variant of Blackwood we were using (this was a standard Blackwood situation), so I tried cuebidding first, but my partner responded 4NT anyway. I was forced to make up a response and ended up at 5♠ just made, losing to an ace and an offside king.
Turned out that we were the only table playing in ♠. 3 other tables played in ♦, 2 of them didn't even bother to find a ♠ fit after 1♦ opening (one raised to 4♦ directly, another splintered 4♣), and the remaining table was unable to find a ♠ fit since W opened 1♥. There was one table playing in 3NT as well, the same table who played 3NT in the last board. I was surprised that so many people didn't even bother to find a major suit fit after 1♦ opening even in MP scoring.
Board 13, sitting W:
Double-dummy result is +1 but it requires finessing the ♣K once then drop it the second time, which no sane person will do. A normal line of play should result in 9 tricks. However, we got lucky that the opponent attacked the ♥ themselves, giving us a few more tricks in ♥ for us to run our ♠, resulting in another top for us.
And the final wild board 14, sitting W:
After 1♣-(1♦), I Xed to show both majors. N bid 1♠ and my partner bid 4♥. At that moment I knew this was wild and it would be some serious swings. Using the information given, I believed that my partner must have ♠ shortness so I considered no ♠ loser, and partner's opening bid meant he very likely had a cover for my ♣ loser as well, and I made up my courage, picked the 6♥ bid, which my partner made 12 tricks.
Among 5 tables, we were the only one who actually bid a slam. 3 other tables ended up at 5♥, and 1 ended up at a disastrous 5♠ by W. Those 3 tables who ended up at 5♥ all had the auction preempted with 3♦ after the opening bid, and the disastrous table had the bidding 1♣ - (1♦) - 1♠ - (3♦) - / - (5♦) - 5♠ - (x) - //, where the ♥ suit was never shown.
And finally we ended up at the middle of the ranking list.
