Pre-flop: (6 players) Hero is CO with 7 :diamond: A :diamond:
2 folds, Hero raises to $14, 2 folds, BB calls.

Flop: 4 :diamond: 2 :heart: J :spade: ($30, 2 players)
BB checks, Hero bets $21, BB calls.

Turn: 6 :spade: ($72, 2 players)
BB checks, Hero checks.

River: K :club: ($72, 2 players)
BB checks,

Worth a bet here? I think my line is probably too obvious for something like JT, QJ to fold.

Not with this villian I prob wouldn't

I'd only value bet the river, not bluff, at least without further reads.

against a standard player, yeah. but not a 52/17

I check this river against a guy with those stats almost always.
