I'm about 20 hands in, so reads aren't the strongest.

Hero (BB, $800): 32, quite, should be an unknown to the table as I haven't played in this room in years.

V1 (UTG, $450): 50s, Eastern European. Seems splashy and willing to bet / go away when there's aggression.

V2 (HJ, $800): 20s "poker-pro" hoodie look. Seems slightly tilted / unhappy about how he's running. Haven't seen him get out of line.

Hero is BB with 35

Preflop: 6 limpers, SB completes, hero checks.

Flop ($40): 422

I check, V2 bets $20, V1 calls, Button calls, hero calls

Turn ($120): 6

V2 bets $65, V1 calls $65, Button folds, Hero raises to $265, V2 quickly folds, V1 quickly calls

River ($715): K

Hero and villain each have about $510 to go.

Hero . . .?

was the turn the 6 because I don't see a completed flush on the river?
and how does V1 still have about $510 to go by the river if he started the hand with $450?

+ 1 to confusion above. If the 4d was actually 4h OTF, I still need to know which V we're facing.

Out hand is basically a bluff catcher if the title is true, so c/c to catch bluffs, in most circumstances, imo, but hh is so messed up that I really don't know.
