North opens 2♦ in 4th hand:
2♦-2♥
2NT-3♦
3♥ All Pass
2♣ opening would have been a preempt with 6c♣ or 5c♣ and 4cM.
3NT opening would be preempt in a minor.
(Probably not very usefull in 4th hand, but then assume North opened in 3th hand).
Therefor North opened with 2♦. South can show preempt or invite in ♥ by bidding 2♠, but because he knows that N is strong he bids 2♥ to give North some space.
2NT shows 22-24 HCP. North could have bid 3♦ to show a GF in ♦.
3♦ after the 2NT was transfer to ♥ and 3♥ denied a 3 card ♥.
Should we have reached 3NT giving these methods?
(most of the field were in 3NT)
