weird value question

[HIV]

villian insta-called turn so I kind of figure he's got an ace or six more often and 2 pair/set sometimes.

he seems pretty bad imo as he calls too much postflop and limps a lot preflop. no pt stats so idk how bad he is exactly and how he thinks in this spot about there being a straight on board.

is this an obv shove for everyone or smaller vbet or even a check to induce bluff?Full Tilt Poker Game #1563074831: Table Kennedy (6 max) - $50/$100 - No Limit Hold'em - 3:48:54 ET - 2007/01/09
