1,2, and 3 look okay to me since you are OOP. You could stab at the turn in hand 3 to rep AJ but he prob calls anyway.

Hand 4 is standard against a shorty. At $25 there's a lot he could push here (FD, 77-QQ, str8 draws) that aren't sets, so I call up to 100 BBs most times.

Hand 5--He can have AA/KK but if so then meh. If he flopped str8 then you have redraw. If he has AK/AQ/AJ you are way ahead. Good push.

Hand 6 is standard, good call preflop, get it all in on flop if you can. JJ/QQ sucks but is only small part of range.

Hand 7 you could check behind turn for pot control. Flop raise is okay but when he calls he has to have something. As played when he pushes the rest in you have to call. He only had pot behind so all the money was going in when you bet.

Hand 8 is sick, I think I fold river. Cbet that flop in position though...and if you are going to raise the turn, raise to the size of the pot to force an unmade draw into a bad call.
