this is probably going to be pretty similar to other posts so i'll try not to make it too long
H1) seems fine
H2) raise more pre especially because the caller, I like the flop and turn if you have a read on villain that he's going to be calling these overbets with draws/small pairs/overcards.
H3) raise atleast 12c pre, only other thing about this hand is I don't like your reasoning for c-betting.
H4) I like checking this flop if villain will cbet this flop frequently because I think we'll often get more value from the btn with a c/r line. donking is fine, but I think our bet does have to be larger to get more value from draws (they're probably going to play their hands the same whether or not our bet is 10c or 18c), and to build the pot to get max value from top pair type hands on later streets w/out overbetting.

soooooo pretty much everything jkds said
