What will you bid as South?

Against 2♥, your partner led the ♠A. You encouraged with the ♠9, and your partner continued with the ♠3 to your ♠K. You then played the ♠2, which your partner ruffed, and they played the ♣10 to your ♣K. How will you continue from here?

You're playing 6♦. West led the ♠10, which you won with the ♠A (you tried the ♠Q but East covered it with the ♠K). What will you do next?
