Hand 1: I don't like that line with bottom 2, or any 2-pair at that. I like to keep my bets relatively small as 2-pair is often vulnerable. I call the raise on flop and make another pot-sized bet on the turn.

Hand 2: As much as I hate it, a min-raise here would probably suck SB into the pot and get the chips in on a later street.

Hand 3: Fine, small pot, he could easily be doing that with an ace.

Hand 4: I don't like the river bet against a calling station with air. Check it down.

Hand 5: This is at least better than hand 1 because you have top 2. I think playing like this against an aggessive donk is fine.

Hand 6: If pre-flop action at this table is passive, I might just call from EP. I wouldn't ever raise that hand. As played after that fine.

Hand 7: I'd raise that weak-ass bet on the turn to about $12. Had you been making a lot of CBs? SB might be trying to get you off the hand on the flush and then maybe picked up a flush draw on the turn.
