I guess, I'm just wondering if the long club support, hands are eliminated. Perhaps pass by Opener and double by Responder shows a hand sort of like this, maybe not void in hearts though. But, surely, it doesn't suggest Opener should ever correct to diamonds.... so.... Not much else to choose from.
In the extremely unlikely event that east is interested in diamonds, say x x AJxxx AQxxxx ( I know, he can’t have that on the actual problem), he bids 4N over the double, if he chooses to pull it.
It can’t be to play, since he’d have doubled 4H or passed the double, and it certainly can’t be keycard, so diamonds with longer clubs is all that’s left.
