If diamonds are 3-2, we're making on any sensible line. We really have a choice of 2 lines that cater for possible 4-1 diamond breaks.
We can eliminate hearts and clubs and then duck the first diamond making when someone wins with a singleton. The problem there is once we start eliminating, it shouldn't be too hard for the hand with 4 to find the crocodile coup, so we are essentially banking on singleton queen (and not with stiff trump).
The other line which I prefer requires West to have 4 diamonds along with the presumed ♥J. For this, we draw 2 rounds of trumps, and then duck the first diamond without eliminating hearts and clubs. If a diamond is returned then win, run the ♥K, and then ruff a club in dummy to start rattling off your own trumps. If a club was returned, ruff the club first, then we can decide if we want to trump-squeeze East. However, if that was working, East would probably have returned a diamond breaking up the trump squeeze, so I would just play for the squeeze against West unless East was sufficiently short in both black suits.
edit: Justin's line above is a lot better imo.

I found this one in an old chat with my friend Andy Hung.
I didn't get it at the time but 2 years later my brain somehow clicked!
Give it a try.
6♠ by South. ♥Queen led. You play the ♠Ace, all follow.
