one thing i would say is that i would tend to bet again on the turn in hand 1, check calling is putting a big sign out that you can get taken off your hand, if he re pops the turn you can fold anyway, brave man only bluffs the river to a check or value looking bet.
I think this is one particular weakness of mine, betting the flop, then going to check/call mode if oppo doesn't fold. Will work on it.
