I know you didn't hold this hand, because you would have bid 2♥ over the double and might not have chosen the spade play at trick one.
If your partner had the ♠KJxx(x) he should play the jack, as you didn't lead away from the ♠A. This way he locates the ♠Q right away. Of course, your attitude type ♠7 lead already would have told him that you lack the ♠Q. Partner also might have ♠QJxx(x), but you can place the ♠T as PROBABLY being in declarer's hand.
What information do you want to share with your partner.
