I've been playing like ass lately, but here goes.

Hand 1. Looks ok to me. Maybe c-bet just a little more. 150 seems like a good bit more psychologically to me than 125, but maybe I'm nuts.

Hand 2. Ug. I think you can find a better spot than this. Read notwithstanding, A-J offsuit aint that great, you still have players behind you, and blinds aren't that high yet.

Hand 3. Looks ok. I probably wouldn't even have called the river bet. Maybe I'm too tight.

Hand 4. Best hope is a race. You have no fold equity. Good laydown.

Hand 5. I think your overbet screams bluff, but I'm not sure on how I would play this. Maybe some better players will weigh in.
