Blind resteal gone bad.

[Nottom]

Note: I originally posted this in mid-stakes by mistake. Sorry about the double post.

10-20 on WPEX. Haven't been here long so I don't really have great reads on the other players involved in the hand, but so far they seem pretty typical.

I have QJs in the SB.

Folded to button who raises, I 3-bet. BB caps, we both call.

Flop is KJ4r.

As usual, I'm completely lost and check. BB bets, we both call.

Turn is a blank. I check and fold to a bet-call.

I know I play bad, what should I have done instead?
