Bad play, psychology, variance..?

I dont like the way you are playing those hands. I mean two overs, 3 to the flush when u have no flush out. Maybe you dont know when to fold? Calling down is probably costing you 1-2BB quite frequently. You need to consider your opponents and their inability to fold to preflop raises, will they call a2o to a raise against KK, some will. Especially at 1/2 2/4 or lower
