Add dummy's hand to the diagram, then append &p=h7hth9hqd2d3dad8dkc3d4c4d7s4d9s8dts2d5s5djs9d6s6dqh3c9c5skc8s3sa , and it will be much easier to follow.

Close enough

Partner has AJ8 of hearts and 2 clubs left, so I'll cash the ace of clubs and then return the heart.

The ♠ carding does not seem to make sense. Partner played their 3 cards 8-2-9 instead of the expected 9-2-8 and we played ours 4-5-6-A instead of the more normal 4-6-5-A. It probably doesn't matter but it is a good indicator that we probably can't trust our signals too much. Outside of that, this seems to be a matter of finding a layout where there is a difference between playing ♥6 and ♣A now. If there is no such layout, I am probably not understanding the question. It might potentially be a more interesting position in a 2NT contract...

I'm talking this through with my partner, I think they are giving attitude/count whenever they can, I play only attitude, only first trick unless count is obvious.

I'm obviously missing a lot in my understanding of signals. Low-High encourage so after playing the 4, either the 5 or 6 completes the sequence, ie I've not lead 4 from 432. However, if I play 465 partner knows I have 3 to my honor(s)?

[Gilithin]

You talk about leads in your last post, which is a little different from just giving a signal. On signalling, the most common arrangement is to give attitude, count, suit preference in that order. If a signal is irrelevant you can skip it (though some pairs signal more rigidly than others) so, for example, a common agreement is to go direct to suit preference if the opening lead is an ace and dummy turns up with a singleton in that suit.
On declarer's lead it is also common to skip attitude, since that often helps declarer more than the defence. So if partner leads the suit and we give 2-3-4 we are showing encouragement with an odd number. If 2-4-3 it is encouragement with an even number; 4-2-3 is discouragement with an odd number; and 4-3-2 is discouragement with an even number. Whereas if declarer is leading the suit, 2-4-3 is even and prefer higher suit; 2-3-4 is even and lower preference; 4-2-3 is odd with lower preference; and 4-3-2 is odd with higher suit preference. But other arrangements are possible - important is just that you and your partner understand the differences and can explain them to your opponents.
