BU is a 5/10 reg, seems like a competent 2p2 level player, not particularly loose or tight, capable of 3betting light and understands what a squeeze is like most regs at this level in this casino. He usually buys in for 2500(the max) and did today. He hasn't played with hero much, but he probably knows hero is a 3/5 grinder.
Hero has a very tight image this session. However, hero has 3bet 2 or 3 times already. Earlier this session hero opened 6 handed UTG 35 with AKo, was 3bet to 135 by villain on the button, and 4bet to 370 with 800 behind, villain folded. Hero has not show down any hands where he 3 or 4bet.
Hero has 1480, BU covers.
UTG+1 limps, BU raises to 40, SB calls, Hero is BB and 3bets QcQh to 170. BU calls, the rest fold.
Flop(400): 5

Hero bets 210. BU calls.
Turn(810): 7
Hero bets 480, BU calls.
River(1770): K
Hero checks, BU shoves and covers Hero. Hero has 620 left. Hero?
Any thoughts on flop and turn sizing? Once hero bets the turn he has to stack off on pretty much any river, so should he bet more on the turn?
I don't think BU expects hero to have any air on the river, or expect hero to fold the river. If BU is bluffing, what hands is he bluffing with? I can only think of 66/76/TT/JJ. Those hands are probably checking back though because hero is calling with all pairs in his range except JJ (which BU might correctly think hero does not 3bet pre).
