The form of scoring might matter. At matchpoints he might decide to try for down 1 but even then the third heart is premature. Ducking a club seems like the best try for 11 tricks.
But wait. What about T1???
As far as inferences go, it is the spade play at T 1 that gets my attention. Rho played the 6? We should be able to draw some conclusions from that. If Rho holds the QT you would expect the T to be played and really the T from KT also since pard has hardly underled an A here. Anyway, not the 6. The auction might matter a bit, since perhaps Rho could be confident declarer has the stiff A, but still the 6 is a very surprising card and it would be reasonable to think that at least maybe Rho has exactly what it turns out he has. If he is, say, missing the 9 why would he play the 6 instead of the T?
As to the pitch of the
K later, pitching a spade seems completely natural, and if the K is anything it is probably suit preference. It wasn't but it could have been. Maybe reverse suit preference? Who knows? To borrow from Freud, sometimes a spade is just a spade.
The inference from the T1
play gives us hope but there is also the inference of What Else? We are going to put Rho in with a
and if he has a
that he can and does lead then that might allow us to score our J but we will still lose a
. So we have to make sure Rho does not have a
when we put him in. So we lay down the
AK. Voila, the Q falls. Now we are home if Rho holds either 1 or 2 clubs. Can he hold just one club? That makes him 7=3=2=1 but it is possible. So we lead a
to the A on the board and then a small
from the board. If the small
is ruffed that's fine, he has only spades left in his hand. If the small club is not ruffed then we take the A and lead a
.
As mentioned above, that
6 at T1 could give us hope that this play is working, maybe Rho should have played a higher
hoping to deceive declarer. But of course that could deceive partner also.
Still, I think the logic is: If Rho has
Qx and
x or xx, we can make this, and if he doesn't have that holding then as near as I can tell we cannot make it.
