6 handed game, several hours into the tournament. Blinds 75/150/25.

(23k) Villain is UTG (fairly tight mid 20's asian guy)
(19.5k) Hero is BB w/ 68hh (most active player at the table, taking down majority of small/medium pots, lost big pot flush over flush 20 mins prior)

Villain raises to 450. Button calls. Hero calls. Flop is 234hh

Hero checks, Villain bets 750, button folds, Hero x/r to 1950, Villain calls. Turn 4s.

Hero ponders... bets 4500. Villain calls. River 8c.

14.5k pot. Hero has just under 13k left. Hero ???

In hindsight, the turn 4 was a bad card to bet. However, what is the best line as played? If the turn was a 10s, is this always a river jam?

First post... any input is much appreciated! Rip me a new one if you feel it is deserved I want to improve my game.

Cheers
