Villain just sat down maybe 2 orbits ago. Plays a bunch of hands passively preflop it seems.
UTG limps. Hero mp1 ($1,200) raises to $25 8♠ 6♠. HJ calls. Villain in BB ($900) calls.
Pot $75. Flop T♥ 7♠ 3♥ . BB checks. Hero bets $40. HJ folds. BB calls.
Pot $155. Turn 2♠ BB checks, Hero bets $85, BB calls.
Pot $325. River Q♥ . BB checks. Hero bet $235.
(I know it's a little loose preflop. This is not a usual raise for me)
Turn sizing? Good river to bet? River sizing? Against an opponent I know almost nothing about?
