The point about ducking the 1st ♦ is valid.
Indeed, it is the way to avoid the blockage possibility.
Partner presumably has led from J10x or from length, which may include KJ10x(x).
The critical holding is when partner has led from KJ10xx.
Playing the 2 back, which is the accepted play from an original 4 card holding, creates a problem at mp scoring.
Partner will win the 10 and have to decide whether to underlead the K or play the K and block the suit.
This would be no problem if he held another entry. He could underlead the K, losing to declarer's hypothetical Q8, but be able to cash the suit on regaining the lead. And, in a similar way, he could play the K, blocking the suit opposite your Q8, knowing that he can get back in after you cash your ♦.
But he has no entry.
This is almost a non-issue at imps as well, since with that 5 card ♣ suit in dummy, the odds are high that underleading the Kxx (after winning the 10) would cost only an overtrick when 'wrong', while blocking the suit is likely to be fatal.
Partner may have some clue from the cards played by declarer when declarer has xx, but most probably partner will be guessing at trick 3.
So there is some logic to winning the A and returning the Q. It loses when partner led from J10x, and you end up being embarrassed by declarer's K7xx.
So it is a guess: either for you or for partner: all of which takes us back one trick: why on earth did we put ourselves in this position?
It is basic bridge to think before playing to trick one, and the thought we should have had was 'if we win this trick, which ♦ are we going to play back?'
Had we done this basic thinking, we would have NO problem now.
So if the point of this question was to make us think, it came one trick too late. It is making us think not about correct technique at this point but about how best to guess our way out of a silly situation that we created by thoughtless play.
