I haven't analyzed it carefully (so I probably shouldn't comment) but it feels wrong to block the clubs like that. Don't you risk getting locked in dummy?

- Win ♦A, ruff a ♦ in dummy, cross to ♥K, ruff another ♦ in dummy, cash ♠A, cash ♥A (throw 4th ♦), then start playing clubs ending in dummy
- If clubs break 3-3, play a low spade towards hand at trick 10 intending to put up ♠Q if East follows
a. If East shows out, we duck (instead of playing ♠Q) and endplay West to score one more trump (makes 10 exact)
b. If trumps were 4-1 on the right, play 13th club after winning ♠Q (makes 11 tricks)
c. If trumps are 3-2, and King is doubleton on the left, we make 11 tricks
d. In other 3-2s, we could make either 11 or 12 tricks depending on the distribution
- If clubs are 4-2, some good things can still happen (e.g. the person with xx in clubs also has Kx in spades) but mostly opps will score their three trumps separately while we make our 10 tricks
However, I'm not sure how many times this gains vs. loses in MPs. I think manudude03's line offers much better odds for overtricks.

Assume it looses, nothing dangerous can happen short of a defensive cross-ruff, which is very unlikely.
Say a ♣ comes back.
Win in dummy, cash the ace of ♠ cross to the♥ king and ruff a second ♦.
If this gets over-ruffed you still have another entry in ♣ to reach the ace of ♥
If a ♥ comes back ruff a second diamond immediately.
In the unlikely event that this gets over-ruffed only a ♣ or ♥ ruff could hurt you.
Win the return in dummy and cash the ace of ♠ and then the ace of ♥, discarding your last diamond.
Similar if a ♦ comes back ruff in dummy and whether this gets over-ruffed or not next try to cash the King of ♥, the ace of ♠ and then ace of ♥.
This line looses sometimes when West has all 5 ♠ or if West has the king doubleton in ♠ and at least 6 cards in ♦ and and either a void in ♣ or a singleton in ♥.
This line never looses if ♠ are 4-1 or when East has 5 ♠ .
You will loose at most 3 trump tricks.
This line also preserves your chances for over-tricks

Haven't you now used both of dummy's club entries? But maybe you meant to win the second club in hand.

No, I have not. Where did declarer play clubs so far? Declarer never played ♣ himself and has two ♣ entries ace and queen in dummy. He lost the lead only once before in trumps and the opening lead was a ♦. Also if East over-ruffs in ♦ he can only cash his remaining trump if he held JTxx in ♠ but will then have to lead a ♣ or ♥ himself.

I would lead the ♠9 at trick2, covering any higher card with the ♠A. with the intention to finesse the ♠A,7 at the next opportunity. Gives you some good cover for spades breaking badly and the possibility of the ♦10,9 coming into play.

Sorry - for some reason I thought they'd led a club at trick one.
