Six of the tables had the simplest auction:
When all Wests led ♠T, all Easts were clever enough to duck and make things less clear for declarer.
The other four Souths opened 1♠, but had various auctions after North responded 1N. One South rebid 2♠:
East was protecting against West having underled ♠A or ♠Q?
Two Souths rebid 3♠:
Those two Wests led small ♦. I would have thought this auction made it more likely that South had ♦ honors, so underleading the ♦K would be more dangerous, but my opening leads suck, so maybe there's a good reason for this lead.
The last South rebid 4♠ and got a ♥ lead. Very unlucky...
