The problem is that after the initial diamond and cashing all of the majors, you are on the board with nothing but clubs.
W can keep the
T and the
K98. So now you could drop the
T if you could get to your hand, but you can't.
E holds on to
J73.
If you lead A and a small
then the A takes the Q and leads to the J.
Nothing can be done, I think, if you come to that ending.
The solution, surprising I think, is to cash only 7 of the majors ending in hand. Let's say you cash all of the spades, throwing a
from hand and then cash three
ending in hand.
So 8 tricks have been played.

In the first case you play A and another
, W is in and must lead a

you go to the board in
and cash your
In the second case you play A and another
, W has to lead a
, and whether small or large you get the two clubs and you have the transportation to collect both the
A in hand and the
5 on the board.
It's a fun hand. Certainly against the odds to play it that way, even if the possibility occurred to declarer,but it does work.
