Spade AQ8xx
Heart --
Diamond AQT9x
Club KT8

Spade Tx
Heart x
Diamond xx
Club AQJxxxxx

You opened 3Club, LHO overcalled 3Heart, partner bid 7Club after exclusive RKC.

Opp led a trump, trumps were 1-1, so, is this a 50% pure guess??

Is that to finesse in Diamonds the superior line? As singleton DK onside would see you home by ruffing finesse of DJ on the way back (yet, if finesse Spades, singleton SK onside offers no help, still need to finesse DK).

or should be played like this?

Cash the DiamondA first, to see if DiamondK drops. If not, fin Spade. You would make if DiamondK drops, or SpadeK on side when Spade is not worse than 4-2

Going up with the SA, back with a trump (1-1, lucky!) then finesse in diamonds. Still makable when DK onside no worse than 4-2/2-4 PLUS DK singleton onside (ruffing finesse DJ).

If you put in SQ, you make when SK onside no worse than 4-2/2-4. No SK singleton onside case (you can't make it even if the lead was singleton SK anyway, still have to rely on DK).

Well, you may always add some "psychological" factor, e.g. "He won't lead away from honors." or "He must be bluffing and leading away from SK". Only that could be another topic.
