Sanity check battle of the blinds hand

[adanthar]

16 left in the Stars 11 rebuy. I'm around fifth with a ~500K stack and 15/30 blinds and have been running over a lot of people.

Folded to me in the SB and I raise K8o to 90K. The passive BB with 425K calls (he was on my right for most of the day and raised my blinds *once*/gave me about four walks).

The flop comes K93r. I check. He bets 90K (half the pot). I call him down now, right? (Also, would betting and folding to a raise be better?)
