Villain is a good reg who likely perceives me to be a little spewy based on history. A few hands before this, I had reverse-floated him on a KQTcc board in the BB and then led turn and river on a Qx 4x runout, he called down with AJ - I didn't like my play in that hand.

I elected not to 3-bet here because we're very deep and I expected villain to put me in some tough spots postflop as well as 4-betting quite frequently, so rather than get into a massive pot in a very soft tournament, I chose to defend a fairly strong hand. I probably 3-bet this hand here with at least a non-zero frequency, though. I imagine my 3-betting range is very narrow here against a player I expect to put me in some tough spots.

This is probably the bottom of my value leading range here. I would also be leading a lot of FD/gutshot combos and KJ combos, as well as any 2 pair or set. The reason for this is that having check-called the flop and led turn on a previous hand as a bluff, I think villain is likely to interpret my leads as being weaker than usual.

When villain raises, I thought about 3-betting, but in the end decided villain was bluffing often enough that calling and calling all turns was probably better.

It's worth noting here that when villain was value-betting the KQT flop earlier, he bet big, around 75% of pot on flop. He bets big again here. I call, since villain can be doing this with FDs and maybe even with KQ for value, and I'm expecting to call off on river versus a shove fairly often.

This is where it felt a little weird. It seemed really unlikely that villain would still have many bluffs in his range at this point, especially with sizing. I'm not too worried about being exploited here since I do think I have a reasonable number of bluff-catchers in my range here (QJ, some sets, QhXh), so I figure since AQ is actually reasonably close to the bottom of my range right now, I can probably fold it even to villain's small sizing.

Any thoughts on this at all would be welcome. I feel like it's entirely possible I could have played it fine, or botched every street. Really not sure on this one.
