My mentor always told me when playing a hand to ask myself "Which hand is the master hand? Which hand am I trying to set up?" after the opening lead is made and before playing a card from dummy. That's the time you formulate your plan for playing the hand. Those questions can lead to determining what possibilities exist for playing the hand.
Typically, the long trump suit hand is the master hand. But, occasionally, there might be a possibility for a short trump hand "dummy" reversal where you set up that hand.
Looking between your hand and dummy, those questions lead you to a couple possibilities. One way would be to ruff out your ♣ losers in dummy. Another possibility would be to set up the ♠ suit in dummy.
Some follow up questions need to be asked -- especially with slams " What can go wrong (bad distributions, etc.)? What can I do to get around it?"
The problems are if ♦ break badly and/or ♠ break badly. But you may reduce your chances of making a great deal if you lose the first ♥ trick.
And also, you might ask yourself "Are there any ways to combine chances?" If one plan doesn't work than you might have a fallback.
You should see that if ♦ break 2-1 you can draw trump, pitch your ♥ loser on the ♠ A after unblocking, and ruff 2 ♣ in dummy just giving up 1 ♣ trick at the end. But if trump are 3-0, you have to ruff 3 ♣ in dummy and limit yourself to 1 trump loser which may be hard to do.
The alternative to ruffing ♣ is getting rid of your losing ♣ on long suit trick winners in ♠. If ♠ are 4-2 or 3-3 you can easily set up 2 pitches in ♠ and still be able to ruff a ♣ in dummy if necessary. Even if 5-1 you'll have some chances if the ♠ honors are favorable placed or have a sure trick way of setting them up if you crash the ♠ 10 or ♠ Q when you play to the ♠ K.
So, to keep both plans open you need to play to the ♠ K early. That way you unblock ♠ yet preserve what might be vital entries to dummy in setting up ♠. The risk you take is a ruff if ♠ are 6-0. But that is small compared to the flexibility you'll have if you find a 3-0 trump break.
Win the ♥ A, then play a ♠ to the ♠ K.
Play a low ♦ to the ♦ A. If both players follow, you can follow your plan to draw trumps and ruff ♣. Alas RHO shows out.
Play ♠ A and pitch your ♥ Q. If both follow, you can then ruff a ♠ and have enough entries to set up 2 pitches on ♠ and still have a ♦ to ruff your last ♣. If LHO ruffs, you'll have 3 entries to dummy to set up ♠. If LHO pitches, continue with a high ♠ spot (J98) pitching a ♣ if it's not covered and ruffing if it is. One way or another you'll be able to set up 1 pitch on ♠ and 2 ♣ ruffs, or, 2 pitches on ♠ and 1 ♣ ruff. Note that once LHO ruffs a ♠, the next lead will allow you to get in and draw the last trump with a high trump entry to the dummy.
