Your partner opens the bidding one diamond in second seat. RHO passes and you respond one heart holding:
Partner’s rebid is two clubs and it’s back to you. Don’t you have a game forcing hand with your nice 14 points? Your call?
Please respond in the comments. I will post my recommendation Wednesday evening.
Update: This is a perfect example of the opportunity to use 4th suit forcing to game. Bid two spades. Partners next bid should help guide you to the right spot.
