All of these lines look to me like how most players play monsters, I fold all of these (unless you often see these lines as being bluffs or something, which is highly doubtful). The only thing I'd expect to beat in these instances is one of those badly slowplayed high pocket pairs.

In the T6o hand I usually bet the flop too, but weaker, more like half pot. Might be stupid, weak bet for a weak hand, but I do it for pot control mostly. If I don't bet, only way I'm winning this hand is if it gets checked down through the river. Usually I can take it on the flop. If I get callers, I'll fold to further aggression, and win a showdown vs a lower pair or a draw that never got there (ie, only thing I beat are hands that are looking to showdown cheap too).
