My point there was not only that the declarer correctly guessed clubs but the tempo he used. I still don't know if a good declarer, guessing 4♣ to E , will take the ace ♦ and finesse ♣ at the second tric. I suggested another line, winning the ♦ in your hand, cashing ace♣, returning a ♥ to the dummy and then finesse the ♣ next time when u get to the dummy. Does it make any difference? More, i would play ace♥ then ♥ for the simple reason of a stiff k♥in the west's hand. In addition,if W ducks the heart i could get new info's.
