This actually happened in today's club game. How do you rule? 1. RHO opens 1NT, you bid 2 clubs. Partner explains this shows both majors and bids 2 spades. RHO passes and partner then says, “I erred, 2 clubs shows a single suit.” Holding 3 spades are you allowed to bid 3 diamonds? 2. RHO bids 1NT, you bid 2 hearts. Partner explains this as holding both majors. After 3rd seat bids 3 diamonds, partner bids 3 spades, holding 6 spades. RHO doubles and you bid 4 clubs, holding a singleton queen of spades. Partner says, “I erred, 2 hearts shows hearts and a minor,” and then bids 4 hearts with 2 card support. Is this legitimate?
