Pairs
2♦ is a multi showing either a weak-two in hearts or a weak-two in spades (no strong options). South's Double shows a balanced 12-15 or a strong (20+) hand.
What are your methods over the double? Our agreement is that we largely ignore the double and bids of a major are pass or correct as in an uninterrupted sequence - the only difference being that 2♥ promises at least tolerance for either major. Without tolerance we either pass (with long diamonds) or redouble (with long clubs). I am interested if others play different methods? And why?
Given that partner would redouble with a weak hand with long clubs, the 3♣ bid is strong.
What action would you take over North's 3♥ bid? Do you double, telling your opponents that they are trying to play in your suit? Or pass and hope that the bidding dies here?
