1. Bet the turn, small river raise (to $90ish) for value, fold to shove.
2. Never 3betting here? Don't like the c/r for value here. Once you do it, I think you should keep the initiative and bet the turn and river, hoping to get called by AT/A9/Axs. As played I think you're beat on the river.
3. Fine. Prefer it with a read and against a full stack.
4. Bet/fold. Bet river if called.
5. Fold pre. Flop is fine, turn is good.
