Both of those hands are just coolers, the second one you need to bet a lot bigger on the flop, like 17c, it probably would not have changed the end result but its better poker. At the 2NL you need to be betting big for value every single time you hit something, slowplaying basically never. Dont be tricky, just raise pre when your supposed to, 3bet with your really good hands and bet bet bet your good hands when the flops are good and youll beat 2NL in no time.
