Hand 1: I prefer just flatcalling preflop with 22 in that spot, but if you decide to squeeze, I make the bet bigger. 3$ or 3.5$. Cbet is fine, but I give up on turn.

Hand 2: I know it looks like a mid pair, but I just fold here.

Hand 3: Depends on my image, if I have been pretty aggressive at the table, I like the minraise. If I haven`t I just call flop and checkraise turn, since I expect villain to fire again, due to the spades on the board.
