(2D)-4NT?

2D is
a. diamonds weak
b. diamonds intermediate
c. diamonds strong
... and I can prove it with my usual, flawless logic.

I assume that the 4NT call was an overcall to 2♦ and not a response.

First, it is bizarre and an invitation to disaster regardless of whether it has a worthwhile meaning.

Second, over a weak or even an intermediate 2♦ opening, since with a very strong balanced hand I would expect direct seat to double, the 4NT bid must show 10 playing tricks, a very strong hand, and a high card (A or K) control in diamonds. Something like:

AQ AQ Kx AKQJTxx

This would allow advancer to properly evaluate his aces and kings as tricks for slam purposes.

Over a strong 2♦ opening the 4NT bid is a puzzlement. It must show a wildly distributional hand with clubs and a major, but I can't imagine why someone would want to by-pass the 4 level to show this.

já, 2D opening on your right and you bid 4NT.

I had take it as clubs and diamonds over 2 ♥ or 2 ♠, so I would take it as clubs and hearts now.

If 4♣ is ♣+M, this DNE imo.

If 4♣ is just ♣, this should be ♣+M.

So you are saying that 4NT is ace-asking?

GAH!!! Thought I could out-search the search master.

But there was definitely a post somewhere where Helene talked about this bid in the context of leaping michaels.

11 sure tricks in clubs or a major, bid 5♣ without aces and be prepared to raise 5M with the king of trumps.

If 2♦ is strong then it is clubs and a major

Same as a 4N opener over weak/intermediate, not sure over strong.

Blackwood for me..a hand that wants to know how many aces pard has and then can place the contract. Ace asking before the possible bump to 5♦ from LHO.
