Sorry dude, but this is terrible terrible terrible. Passive players that limp in in live games almost always hang around - especially if they have any piece of the flop. Bottom pair, gutshot, backdoor draws - it doesn't matter - they're going to call.
Building a multiway pot with a marginal hand is one of the worst mistakes you can make in any no limit game.
CH, you sound incredibly easy to trap. Why can't someone be holding Queen/Rag? Because no one bet? Why can't someone be holding a set? Why can't someone have KJ?
Why would you want to knock someone off a draw here? If you have a set you want a draw to come along every single time as long as you make it a mistake for them to call with your bet size.
In any event, you're essentially playing this hand as a bluff because you don't want to go to a showdown. Bluffing against 4 others in a NL hand is pretty damn terrible in almost every situation.
As I said above, if you're playing to make them fold then you're playing a bluff and bluffing into four others is just about one of the biggest leaks I can think of.
In many situations you up your chances more by checking it down and almost always ensuring the player is knocked out then by chancing letting him basically quadruple his stack.
In fact I think its in most. You def don't have enough equity with middle pair TK to make the bet worthwhile when you consider that.
