OK, I think the defense is incredibly easy here, and that the defenders will cash 1 or 2 rounds of diamonds (depending on who wins the first diamond), and then lead an appropriate major , and if its spades I am worse off then before.
I think you will agree how humorous your assessment turns out to be.
You state that the defense will cash one or two diamonds and then switch to a spade. If they cash two diamonds, like the Ace and King, I am left with the J9x with only the Queen outstanding above this. So, I win the spade and play the diamond Jack. At a minimum, then, I win two spades, three hearts, two clubs, and a diamond. If the fifth diamond establishes, I have my ninth trick without even touching clubs. I also win, now, if the hearts are 3-3 or the Jack drops doubleton. If neither of those work, I still have play, I think.
So, I'm not sure that the obvious defense is all that obvious or costly.
