What does the notrump bid promise on this auction?
Partner opens 1♠ and we respond 1NT. Partner (opener) bids 2♥. Of course, partner’s 2♥ shows 5+ spades and 4+ hearts. He can have a dead minimum, but may also have quite a decent hand (because 1♠-1N-3♥ is GF). What will you, the responder, do next?
Negative doubles are a key part of bidding. What should opener do next?
What is your call after partner opens 1NT?
Should You Bid 4NT?
