All vulnerable.

After 1H P 4H I'm up. My hand is J9xxx void Qxx AKxxx

First question is whether I pass.

I doubled. It continued Pass Pass redouble.

Would 4S show something like this? Better perhaps if we disagree with my first pass? Seems like it should but Idk.

Did you pass in 1st seat? I do not understand the X

Hi,

#1 most would pass with your hand, but going in, ... why not.
Live by the sword, die by the sword, the risk is lower playing IMPs.

#2 I guess, 4S now would show something like your hand, ..., 4Sx ill be
cheaper than 4Hxx, if it makes.
Having decided to go in, I doubt it, would not rule it out,
I would stick it out now.

With kind regards
Marlowe

I would not double here.
But if I do and it comes around to me redoubled by RHO, I am not worth 4S and 5C is a shot in the dark, I pass and let partner decide. He already passed double, despite imagining better honoured spades than I have: he knows about my void and that minors may be 5-3 or 4-4. Maybe he has great hearts and can set the contract, maybe he can scrape up 4S or 4NT or 5C/D, maybe he doesn't want a beer.

For me 4♠ directly is wide ranging, and X-then-4♠ is two places to play, one of them being spades. Bidding 4♠ over 4♥ is frequently a good move (famously for it to be a big stinker both 4♥ and 4♠ have to fail, unless you're going down a ton in 4♠X), so I don't attach significant strength requirements to these actions - the example hand is not near the weakest hand I might join the auction with. Especially with heart shortage we know that we have to act, partner won't be doing anything (particularly after that pass over 1♥).

I think X-then-4♠ is a fine description of the hand but may be only 4 spades, an immediate 4♠ might be better.
Now that we've doubled the auction developed in a very strange way - partner converted our takeout double that can be very light! While this is possible, I think it's more likely a wheel has come off. And then RHO rescued us(?) by redoubling! I don't know what partner is thinking, but if RHO has their redouble then something has gone terribly wrong. Bid a strain and hope to survive, the board is lost but maybe the partnership can survive and even use this as a lesson.
