I don't know how bad checking the turn looking for showdown is, but its clear you dont have a plan with this hand. You raise, and then when a flop that hits your range hard hits you check. Because you have some showdown value, I assumed you were looking for a showdown preferably without putting anything else into pot. Although i do not know exactly how bad flop check is, the most agregious play in this hand was leading turn. What worse hands are calling on a 6KQT board? I highly doubt a ten, or probably even a 6 will fold here so it's an innefective bluff. Have a purpose in mind when you make a bet.
