We were playing precision. Playing MP. Opponents Were Asleep...
1♦ : 11~15 no any 5 card Major
2♣ :
3♣ : 14~15 4+♣fit, 4+♦
3♦ : Double Fit, although diamonds may be 4-3 (In case Opener is 4-1-4-4,
3♠ : Cue Bid / Stopper Bid
3NT : Stopper in Hearts.
My questions are:
Is the 3♦ correct ?
What could north do beyond 3NT ?
If north wants to take actions beyond 3NT(like cue bidding...), should he had bid 3♥ instead of 3♠?
