You pick up white / red: ♠7, ♥10954, ♦8763, ♣9854. You pass as dealer, hear 3♠ on left, 4♥ by pard and 4♠ on right.
Right or wrong, I tried a pressure bid of 6♥. It looks wrong to sell out to 5♠ with this trash, although the opponents bid only 4♠ initially so its hard to tell. we agreed later that a 4N by me is a save-suggestion and 5♥ shows some meat.
Pard gets doubled. Here's the entire hand:
They led the spade to the ace and continued ♥ to the Ace and a ♥. Pard wins in dummy and plays a club to the J and King.
Now pard leads the ♣6 from hand!!!!!!!!!!!! South, playing his pard for ♣AJ and a slow diamond trick or maybe just makes a mistake plays LOW!
Only -500!. It didn't matter though; our pards were sawed off in 5♠ and figured out the diamonds for +850
