Dude, sorry but hand 3 is atrocious. So I get the flop check if you want to get fancy vs that guy, but his fold to 3bet is %80, meaning he actually has a hand now, so why not just cbet there yourself.

And the donk on the turn puts me in WTFland...looks like you are trying some sick leveling game with this dude who probably isn't on a level that you can sick level him. Get what I'm saying. Just bet bet there, or if u want c/c, c/c.
