Hero: 30k
Villain: 23ish

Blinds: 200 / 400 with a 50 ante

Hero has been fairly tight so far.
Villain is a younger white male w/ a nerdy demeanor. Villain is hyper aggressive but appears to be a thinking player. (seen him show down 74s earlier on a HJ open).

Villain opens for 800 on the HJ
Hero 3bets Ah5s to 2200

(In hindsight I think I should of been playing a de-polarized range against villain but with a very nitty image I figured this 3bet would get a lot of credit and villain is opening very wide so it can't be bad. Nobody behind was really a threat to 4bet me often here)

Villain calls the 3bet of 2200

Board: Ks 6h 4d
Check
I bet 2200
Villain calls relatively quickly.

Turn 7h
Check
I choose to bet 5k

(This is one of my better bluffs to have in my range on the turn. I can credibly represent a strong hand and apply pressure to a range of pairs under the K such as 88 - QQ with lots of equity)

Villain thinks a bit and calls.

River 10h
Villain thinks and checks and proceeds to give me the stare down. The live "feel" is he is trying to psyche me out of betting.
Villain has 14.3k left in his stack.

(I feel villain is capped here and I can credibly represent a ton of backdoor flushes, Overpairs, AK, KK and I feel my line looks very strong overall. I'm betting 14.3k into a pot of about 20k so my bet needs to work ~40% of the time here. I feel if he has a one pair hand he's in a really gross spot and my bluff can get folds vs a villain who doesn't want to hero off his tournament in a main event tournament vs a villain hes played <2 hours with.)

As played I shove for 14.3k

Thoughts?
