Hand 1:
Fold. You are crushed by his range and if he can play aggressive smart post-flop he won't pay you off with a PP when you hit TPTK.

Hand 2: 5-10 rule sez call!!!

Hand 3:
Tough one. We're crushing his range, but being oop sucks and if we rr and he calls our c-bet we're screwed. Still, I probably re-raise and hope to take it down preflop.

Hand 4:
Depends if he's a floater. Probably re-raise tho. If he's like the majority of NL100 players he'll instantly put us on QQ+/AK+ and play carefully. Even if he calls our c-bet he might check the turn and we get a free card.

Edit: I though we had the button in the last one (hence the check-behind plan on the turn). Now it's an obvious 5-10 call IMO.
