Made correct call, but ...

[Robbr25]

Should I have.
Villian is very loose, like 80% VPIP
He has bluffed and shown the bluff on many occasions.
When he is strong he bets weak.
Weak he bets strong.
(Yes I know I could/should have raised preflop, but IMO it would not have mattered against THIS Villian)
