Anyway, to answer the question, high from 3 and low from 2 is optimal, I think.

That means that the king can be from AK or KQJ, the queen can be from KQ or QJ10, and the jack can be from QJ or J109. There might be some problems with distinguishing those.

Isn't it better to play third from three and high from two? There's much less chance of ambiguity between AKQ and QJ, or between KQJ and J10.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

In theory, perhaps; in practice, I think that you can often pick partner's holding either way. The other point is that you can vary your play, e.g. from JT9 you can play the T to avoid ambiguity with QJ (similar to the third seat position).

Gszes, you oversimplify it and your example is not helpful.
-I still wait for a declarer with AQJ in the closed hand opposite a singleton to lead towards the singleton.
-When partner leads, you are usually not in 2. seat and we discuss just that.

The problem with low from a sequence is that you or declarer may hold some more high cards in that suit.
So if a trick in a side suit proceeds with x from Dummy, Queen from you Ace from declarer, partner does not know who holds the King. If you play the king instead, partner knows, that you have shortage or the queen. Which case is normally quite easy to see.


the priciple is precisely the same in second/third seat.

the play of the Q from Qxx is almost never a good play. Therefore
the play of the Q practically guarantees the K (lowest of sequence).
Playing the K guarantees no Queen and this allows you to start
counting declarer's hand. It is even worse if you hold AKQ and play the
A unless you intend to continue the suit immediately to let p know
what is going on p has every reason to assume declarer has the KQ.
If you play the Q from AKQ and it holds now p has strong reason to
suspect you played from botom of a sequence.

In your examples you admit no actual information is exchanged and it
depends on other factors to help determine p holding. Playing lowest
from a sequence can indeed give a lot of information immediately.
