Today I played the first time my opponent and it feels good!! Ok, it wasn't a big pot, but who cares?

However, I know that you have to bet/raise nut straights to protect it, especially with big cards (sets possible) and a two flush on the board. But how big is the mistake of slowplaying at the flop from a front position and waiting for the turn?
