After the ♦A pulls trump, cash the remaining heart honor. Cross to dummy in trump and ruff a heart. Presumably all follow and the ♥Q does not appear.
Play a club to the 8. If this wins, you will make 12 tricks by repeating the club finesse. If it loses to the K, you have a claim for 11 tricks.
If the club 8 loses to the 10, RHO is endplayed unless he has the ♥Q. If he has the ♥Q and, presumably, the ♠AK, he cannot have the ♣K as well (or, more precisely, it is highly unlikely that he has the ♣K as well). So, if he does exit the ♥Q, play a club to the J and claim.
By this line, you will make 12 tricks when LHO has the king and ten of clubs, and the only time you will go down is if RHO opened 2♠ nonvul against vul in 3rd seat with AKxxxx of spades, QTxx of hearts and KT of clubs - about as unlikely a set of circumstances as can exist.
You can play RHO for Tx of clubs, in which case you play to the ♣J on the first round and then return to your hand to lead the ♣Q. However, if RHO has a doubleton club, it is more likely to be xx than Tx.
By the way, as was pointed out above, if it turns out that RHO has only 2 hearts, then he is likely to be 6-2-1-4 (he could have 5 or 7 spades, but both of these possibilities are very low). In that case, you should play LHO for Kx of clubs and play a club to the J.
