2/5nl, 1000 eff
Hero raises QQ to 20 from UTG+2, Villain calls two to my left, all fold
Villain has been playing fairly tight. Has only played maybe 3 hands in the hour I've played with him.
Flop: 7h 6h 2c
Hero bets 30, Villain calls after ~15 seconds
Hero bets 70, Villain calls again after a short pause
Hero Checks, Villain bets 200, hero folds.
Is there any reason to bet/fold this river? My thought process was that I don't think I'm getting called by anything worse with the overcard and flush hitting so I can just check and villain will check back any marginal made hands. Is there merit in bet/folding to avoid betting bluffed by missed straight draws or is that not enough of a concern? Thanks.
