I'd be thinking that declarer has misplayed it.
If the other hands are Jxx Qx AQ98 A109x and xx AKxxx xxx Jxx, the second diamond ruff was a big mistake. His correct play is to cash a heart at trick 3 then, when the queen doesn't appear, draw a second trump and try to set the spades up with one ruff - playing either for 3-3 or for Hx onside.
If declarer's clubs are as good as J109, he still shouldn't have ruffed the diamond, because he might have been able to cope with a trump loser by finding
♠QJx onside.
Anyway, I'm going to play
♠Q when he plays one, just in case he's messed up. I don't think this is a matter of fooling him - he's just down if his clubs are J8x or worse.
