This villain seemed decent was playing tight poker pre-flop and seemed positionally aware, their was a little history a few hands prior to this one where i check raised him on the flop as a semi-bluff and he 3bet me off it.

This is the first time he opened my blind so i have him on a preflop range that looks something like this { 22-AA AJ+ }

I'm obviously 3betting for value and i'd like to point out he time banked for a decent length of time before calling preflop, not sure if this is significant but may as well include all information that could potentially be of use.

Do you think i should be c-betting this board? I thought it would be decent as i have a lot of barrel opportunities, i intended on barreling any broadway and all diamonds. I also thought i had decent fold equity i thought he would fold all his missed Ax and low PP's if he had any in his range preflop.

I'm of the opinion that AK should be in my cbetting range here but i'd like to here your opinions on this also?

I honestly think there was a decent chance this guy was bluffing, due to his sizing and this is the second time he's raised me on the flop in a short period of time, is this always a T or better?? Am i just being to suspicious or is there a good chance he's bluffing, and if he was i don't think this would be a hand in my range i should re-pop with as a bluff is it?
