This morning I was dealt on BBO:


AKQJxx
AKxx
x
Ax

board #1, nobody vul, second position.

I recognized the pattern, and after opening 2 clubs starte to speculate about rebidding 2NT so partner could use stayman or something but it went:


pass-2♣-2♦-pass
3 ♦ -

I still tried bidding 4♦, maybe pass is better asking for longest suit



pass-2♣-2♦-pass
3 ♦ -4♦- X -4♥
pass

And I went all in trying even for grand and bid slam, hoping that partner's voluntary 4♥ was a real suit, and not just a preference over my possible majors.

A few years back, I spent many, many hours trying to construct a useful 2C system for standard bidders and the conclusion I ultimately came to was that in order to had some kind of reasonable system some hand patterns have to be excluded or bid differently. A fairly common dilemma to address is the two-suited or semi-two-suited hand. My solution and still my advice - use 2C for NT hands and 1-suiters.

I would have opened your hand 2C but would have treated it like a spade 1-suiter.

Partner had the option to pass over the double of 4 ♦, but chose to show something by bidding 4 ♥. Even if the partner's initial pass over 2 ♦ denied "values" and showed weakness, this subsequent free bid had to be positive in some way. Well judged by both.

One more thought - partner doesn't have to take a preference immediately after the double. Don't you have a route to asking for a preference if partner passes and you redouble?

If she had no preference she should redouble 4 diamonds to force me to pick. Other than that I don't think there is any specific.
