Villain is reasonably tight multitabler. Hero has been reasonably tight on this table as well, but villain might have seen him make some loose plays on a different table.

Preflop: Hero is SB with 6, A. Hero posts a blind of $0.10.
5 folds, CO calls $0.25, 1 fold, Hero (poster) completes, BB checks.

Flop: ($0.75) 8, 8, 6 (3 players)
Hero bets $0.5, BB calls $0.50, CO folds.

Turn: ($1.75) 5 (2 players)
Hero bets $0.85, BB raises to $3, Hero calls <-- by now I'm thinking he most probably is on a BB special with an 8. River could get dangerous for me if he pairs his kicker. Does this affect my implied odds enough to make this a bad call?
