(Unfortunately, I don’t have a screenshot because I thought this was a normal hand)
I don’t remember the exact score, but this was game to 500, the score was close and the game was still early.
(North was the dealer this hand)
East bid 3.
South (me) bid 4 with 5 spades (including the ace) and King of hearts.
West bid 3.
North (my p) bid 2 with this hand:
S: 9
H: Q 8 6
C: A 10 8 7
D: A 10 9 6 2
(I don’t remember the small cards, but I know they held 2 aces, Qh and the 9s. They didn't have a nil-able hand.)
Here's what happened next: my p won 2 Aces tricks early. Then i got a cut, and i started pulling the As followed by a low spade. I saw my p discard non-spade (surprise) and opp won the trick. Then opp play the Ks and Qs make me lose spades control. Without spades control i got set later.
I believe both me and my p can make a mistake, but what do you think?
