I have a strong image, and have shown down good hands all night, but keep getting drawn out on. I've not been 100% honest, and done my share of stealing pots against players that respect my image, but have had the goods when the real bets start flying. I start the hand with about 600.

UTG straddles, 4 people call. I call with 65s in CO, button and BB call.

Flop 7 6 5. Someone early (UTG?) leads 20, and two people call. I raise to 100.

Button tanks. He calls after ~30 seconds. Everyone else folds.

Reads! Button covers me, he is older asian guy, very nice. Me and him and the 1 seat have been friendly all night. He knows I don't put the money in light, and has folded almost always when I have shown strength. Some hands I'd seen of his included calling a small raise in position with 24s, and getting it in for 350 more on a 924 flop. Also, he called a c/r from a donk while in position with 33 on an A45 board. So I think his range is light against fish, but have no reason to think so against me.

Turn: 2. So I was caught pretty off guard by this. The coldcall scared the crap out of me, and I really don't know if this is nuts, or like 86, or what. I was all set to call a raise from one of the folks who led 20, and play the pot IP. Thats out the window...Hero?

If he's been respecting you all nigt and is now cold calling your raise I'd be worried. I would check.

If he is the person I think you are talking about, I would check--if he is on the draw, I am 80% sure he would peel for free and let you see the river. If he plays to you on the turn, I would strongly consider the c/f line here.

Bleh, this spot just screams the nuts. You cant really expect a worse hand to call a bet on the turn except for maybe 87 so I'd check and probably fold to a large bet

I would check and call a small/med size bet and fold to a large one. If he checks and the river comes blank id fire a 1/2 pot bet. Anyone have a problem with this line?

c/f unless he bets an extremely small amount giving you implied odds to stack. He has the nuts, set, or better two pair a fair amount here. Unlikely he calls with one pair or draws on flop.

I agree with this. I do not think that you are ahead here.
