I'm not 100% sure about this auction, but I think this was it.
N/S are playing 4 card majors and a weak NT (2N rebid showing 15-19 balanced and GFing), and seem to be pretty strong opponents (they're both better than me, anyway), though they're a pretty new partnership.
What's your lead?
I took a view (oh, how many IMPs that phrase has cost), feeling the inevitable AK♦ crushing and led the ♥4, hoping to persuade the opps that I'd led a singleton looking for a ruff, and therefore was unlikely to have either the ♣A or the ♦Q. From the fact that I'm posting on here you can guess how that worked out (although partner gave the opps a bit of help, so who knows - maybe it would have worked).
Bad luck? Bad view?

Declarer won in dummy and quickly played ♠Q. My partner (who I should add had otherwise played better than me through most of the tourney) covered in a dozy moment. Had he ducked smoothly, declarer said he intended to ruff the Q."
Presumably ♥6 not ♥2?
IMO ♠ = 10, ♥ = 9, ♣A = 6, ♦ = 3.
