1♦-(1♠)-DBL-(Pass)
1NT-(Pass)-??
1♦=4+card (We open 5cMajor and 4c♦)
In our system we cannot invite with 2NT (that is transfer to ♦), but have to go via 2♣ here.
(Partner often opens with 11pts and often opens 1NT with 14).
The bidding did go (2♦ shows minimum):
1♦-(1♠)-DBL-(Pass)
1NT-(Pass)-2♣-(Pass)
2♦-(Pass)-2NT-(Pass)
3NT-AP
May partner says I have enough and it is better to bid 3NT iso going via 2♣. Now it is clear for opening leader that his partner does not have ♠ support.
What do you think?
