1. Yeah definitely bet but I'd be surprised to see a raise. I guess fold to it though.
2. Calling pre is very meh. If you think you can get value from 99/TT/AKo then they are either cbetting with those hands OR you can donk SMALLER (which would be the main reason to donk IMO). But I'd just c/c and c/f the turn mostly which sucks.
3. I'd b/f but it may be thinnish. He can have some 6x and pair+gutshots and stuff that picked up weak flush draws.
4. I bet your read isn't completely true or else this would be an easy ship. Unfortuntately I guess I'd just fold turn.
5. Call flop and fire most turns if checked to as well as rivers even if we miss.
