♠Q (assume they're not 4-0), ♦A, ♦ ruff, draw remaining trumps ending in hand, cash ♦K throwing a heart, and:

- If trumps were 2-2 and diamonds are 4-3 or Qx-xxxxx, eliminate the minors and endplay East in hearts.

- If trumps are 3-1 and ♦Q is trebleton, throw three hearts form dummy.

- Otherwise take two heart finesses.

How do trumps split?

Anyway, i think we should start with 2 rounds of trumps (Q-A) to get the ♠ picture.

I suppose that trumps split 1-3.

Somehow it is easier for me to imagine that LHO preempted with ♣KJxxxxx♠x and out, than RHO's 4♣ bid with hands like ♠xxx ♥Jxx ♦ Qxxx ♣Qxx or ♠xxx ♥KJx ♦ xxxx ♣Qxx. I don't know who are the opponents and how much they need for 4♣, but i hope he has some values.

So... maybe it is better to finesse ♥J in trick 4(won by RHO with J), and also finesse ♦Q as they return ♦. Sure this line loses to ♦Qx(xx) offside, but it wins on ♠xxx ♥KJx ♦ Qxxx ♣Qxx.
If RHO has ♦Qxxxx it pretty much leaves RHO with ♥KJ doubleton.

Won't RHO just return a club after winning the first heart?

Usually in such situations best defense is to force declarer to make instant guess else he might combine some extra chances.

I think it doesn't really matter this time, does it?

Sorry, I'd misunderstood what you were doing.

What leads were they playing?

3/5 I believe.
