RHO opened. You have 21 hcp. LHO made a free bid, call it 8. If RHO opened some rule of 20 ten count, (1♣) and rebid 1NT, you can count up 39 points. So which Jack do you want to know about? Bid 2♦ after original X, showing the BIG double, and diamonds. If p has a long major, he can chime in.
Where does it convert to penalty double? For sure at 7N. You can walk your way down from there. But eventually you reach partnership agreement land.
You have an unusual notion of what the 1
♥ call promises! 'call it 8'????? Personally, if I hold xxx K10xxx Jxxx x, and we have this auction, I bid 1
♥, just as I would were rho not to double, and I suspect that the gresat majority of posters would agree with me, or at least be closer to my approach than to yours. The 'free bid promises values' hasn't been mainstream in this sequence for well over 30 years, tho it wouldn't surprise me to learn that it is still taught to many beginners.
As for the hand, the first two doubles are routine, to the point that I don't think any decent player would even think there were any alternatives, in any method resembling standard.
I think the 3rd double is debatable, tho it gets my vote since I want to keep spades, or even hearts, in the picture.
The point is that to that point, only the first double was 'takeout' of clubs, but included infrequent power holdings such as a powerful one-suiter or a hand too strong to bid 1N.
The second double didn't resolve that ambiguity....we'd double 1N with any of a BIG takeout of clubs or a power one-suiter or a hand too big to overcall 1N.
Therefore, if we bid 2
♦ at our 3rd turn, logic suggests that this should show the power one-suiter, and I'd expect partner to pass with Qxxx in spades rather than introduce them.
Admittedly, the 3rd double 'could' still be either the uber-strong 1N or the huge takeout double and I don't think it possible to eliminate all ambiguity. However, I suspect that the flat 19 count with a club stopper should and would pass here. So I think the 3rd double should be viewed as takeout.
All of this leads inescapably, imo, to the realization that advancer must pull, and should confidently bid 2
♦...not because he expects to find a 5 card suit but because he has nowhere else to go.
S may have psyched the 1
♥ response, but otherwise it seems impossible for partner to hold 4 hearts, and the repeated doubles suggest 4=3=4=2 or 4=3=5=1. Even if you put 5=3=4=1 into the mix, partner's hand is so good that he'll be able to bid 2
♠over your 2
♦.
