To some extent, it depends on the quality of the opponents.
If the opponents are good, particularly that player, I would think that they know the diamond situation, and they are trying not to release any information about the black suits, that still need to be navigated.
If the opponents are less good, then I might start taking the inference that there is spade length and perhaps the
Q in that hand, and some squeeze potential.
If this were an Arik class, I would take the inference that there is squeeze potential.
I think my plan would be to play a spade to the A, cash the K and if the Q does not appear, ruff a third. If the
Q still hasn't appeared, then play my last two trump and watch the discards before I play any clubs.
On the actual hand, I will know the layout of the spades, but I am not certain I will guess the
Q if the opponents are bound and determined not to give up any information other than what I can force.
