At the crossroads -- The direction I took

When I held this hand, I passed 4♥. Partner, who held:

♠x x x ♥10 x ♦J x x ♣A J 10 x x x,

had taken a false preference to hearts (as he is supposed to do).

My right-hand opponent held four hearts (to the QJ) and four diamonds (to the 10) and when the deal was over, I made 5♥. Passing would have been right if partner held xx in both hearts and diamonds.

With his actual hand, you can make 7♦! with the spade lead. Win, play ace, king and another heart, ruffing in the dummy. Cash the club ace and discard your spade loser. Play a spade to your hand to ruff a second heart. Play the diamond jack, ruff back to your hand to pull trumps and claim. I'm not positive, but I don't believe LHO's diamond was big enough to uppercut the dummy.

I wonder if I should just blast to 6♦ over 4♥?

Maybe I need a map; the direction I took was wrong.
