turn play against inexperienced play with tells

[moneyshot]

very inexperienced player is the villian in the BB.

good 5/10 NL game. Villian has around 800. I have him well covered. I have almost taken down several huge pots in the past 30 minutes with weak hands that I was able to limp in with (57 suited, 68 off) Villian is typical inexperienced player, tends to underbet pots and cant lay down a big hand. In other words, yum yum

Folded to me in the cutoff. I raise to 30 with 45 suited.

When the big blind, checked his cards, his eyes practically jump out of his head. He then decides to think for about 45 seconds and then raies to 75. I call 45 more. He then caps his cards and brings them close to him.

Flop: rainbow KQ4 with a backdoor flush draw. He bets 40 into a $155 pot. I call.

Turn: 5. He wakes up and bets $120. He has about $550 behind. What is your play here? flat call and move him in on the river is a safe card comes (eg. no A K Q), mini-raise here or push here.
