A/Q for unblock just means if you lead the Q you unblock the J if you have it (aka KQT9).

Not a very clear way to say it but it's short.

Seems like in the UK none of my partners have argued against A for Att, K for Count, so I presume that's pretty "standard", however I might be wrong.

In Singapore, well, er, I have seen all kinds of treatment so it's hard to say. Besides, very few people have a convention card!

I have no idea if it is superior, I just find it easy to remember.

So if partner leads a Q and you have xxx(x) what do you discard ?
How do you know if he had lead QJ8x and wants attitude for a ten or if he had led from KQT9x and just want count ?

A good rule is only to discard when you are out of the suit that's led.
and the result can be plotted on a graph.

Watson did not agree with this rule in his famous book but I have not really seen many more examples of this usage.
... and I can prove it with my usual, flawless logic.

I lead Rusinov with strong king.

Yeah, thanks for correcting me there. I should've used "what do you play".

My question is out of interest in how common one or the other is. This is yet another thing where I thought I knew what the standard is...

If you care to provide reasons why your chosen method is superior, please do!

I played Rusnow for a while, then I found that I sometimes forgot the convention which may lead to bigger disasters, so now I just stick with the standard treatment. Q from KQ is quite counter-intuitive to me...

Roger's post was the most compelling for strong King, and I agree with you that, if you do that, you have to switch to rusinow.

Wonder if I am too old to change and remember.

If I remember correctly, "the Journalist" recommended Rusinow leads against suits, but not against NT.

Yes, Journalist vs. NT was A for count/unblock, K standard, Q standard (+KQT9), J denies, T from both AT9/KT9 and AJT/KJT, 9 from T9.

My admittedly fuzzy memory of 50s and 60s era bridge books is that Journalist was the START of using A for count/unblock against notrump, and that one idea from Journalist became standard (but the ten and nine leads never achieved the popularity of ancient-standard or of zero-or-two-higher.)

As I understand it, the "strong Ace" convention means:

AKJT
KQT9
QJ98

which is what I play. Otherwise simply high from (inner) sequences.

"play" covers all of "lead", "discard", and "follow suit"

To echo a couple of things already said:

A/Q for attitude, King for unblock/count is virtually universal among good English players, and seems to be exactly the opposite to North American practice.

You can't stop with your A & K leads you have to consider the lower cards as well.

FWIW I play something my partner taught me which he claimed was derived from a Rubens book:

- A for attitude on the queen (you might encourage with other holdings depending on dummy, the auction etc)

- King for ublock or failing that for count

- Q from a weak KQ holding or a strong QJ holding, initially expecting attitude on the jack (with a strong QJ holding such as QJ109 you don't need attitude on lower honours, and partner knows they can overtake with the king)

- J from a weak QJ holding or a strong J10 holding, same logic as queen leads

- 10 strong, from an interior sequence. Although we are probably about to stop playing strong 10s, because they seem on average to help declarer more often than the defence.

- pip leads attitude (not relevant to the original questions)

The "weak" Q and J leads both tell partner whether it is safe to unblock with the next card up, and allow you to lead an honour from holdings such as QJxxx against a 2NT opening, or KQ9xx, even KQ8x without fearing too much honour unblocking from partner.
