Bad beat, any suggestions

i don't think you made that huge of a mistake by checking the turn. Let's face it, If 8-2 called pre-flop, and then he called any bets on that flop, 8-2 would've called on the turn. 8-2 is obviously one of those players that play horrific cards but likes to gamble. Sometimes it pays off for him, but usually you will take all of his chips.

i think u should have bet on the turn to knock him out but then again it was a bad call preflop, i mean who keeps 8-2 suited in pretty much any situation.
