its 500ish more to call and I truely feel I am drawing to one out...maybe he semibluffed the crap out of me, but more often than not I think I am looking at 66

56 is practically impossible. QQ being limped is rediculous (but you never know vs these nits). 66 makes a lot of sense given pf action and flop action.

I don't know how often nits limp 78s. AK spades is possible but that's the only hand that semibluffs here.

AQ/KQ are also possible but a lot of the time nits fold them to raises in unraised pots OOP...at least I do
