I gave jdonn my answer while I was drunk but it seemed to me that:
LHO does not have the AKQ of clubs (he might have played the queen at some point, and RHO might not have encouraged with Txxx, and definitely wouldn't encourage with 8xxx).
Given that, if LHO has just the AK of clubs, he is a big favorite to have the HA. Eliminating QJx of hearts (would split), then if he doesn't have the ace, his max holding in hearts is the Q. Giving him:
??
Q9x
?????
AKx?
That is only 9 points. This means he must have at least KQ of diamonds...mayyybe KJ but that's a thirteen count. With KQJ of diamonds he might have led a diamond or shifted to a diamond also (unclear, but possible). If you give him J9x of hearts, he really has to have KQ and that is still a thin double that he might not make, or KQJ (where he might have led a diamond). Basically, by limiting his heart holdings to non ace holdings, we force him to have all the diamonds which is less likely. Not to mention we force him to have the 9 of hearts, else our play is irrelevant. Basically it's one big parlay.
Assume we give him the heart ace now.
??
A??
?????
AK??
Obv we don't know the exact shape hence all the question marks. Anyways, in this case he can have KJ of diamonds, QJ of diamonds, K of diamonds, AJx of hearts and the DK, AJx of hearts and the QJ of diamonds, etc. He is also not forced to have the 9 of hearts. This seems like a lot more holdings, and they are all sharp 14/15 counts that would be extremely likely to double (compared to the soft 13 counts above).
Also,
I hate to say this guys, but the weak opps are playing udca. There is a VERY real non zero chance that they play the 9 from J9x or Q9x! 655321 mentions restricted choice, but these people do not know that the 9 could be relevant. I mean to be really honest I think I would play the 9 a non zero percent of the time irl, so I assume that bad players would do it most of the time. Even if you don't believe this to be the case, I still think the king is the right play, but it is a practical consideration that makes the K much much much more likely to be right. In fact, it may be near 100 % to be right if they give count most of the time like most people do. It's not a normal situation, and it's hard to see why playing the 9 might cost when you're looking at KT doubleton.
Edit: Also I realize jdonn didn't say they were bad, I extrapolated that from them Xing and not knowing what it means, and that it maybe means "balanced max" when limited to 15 lol. And yes I use "bad" loosely in the sense that 99 % of people are bad.
