using NOT

[husngforfood]

When does NOT lose it's influence? For example, would it make a difference if there were no brackets here?

tourney_hand_player_statistics.flg_f_bet and NOT(tourney_hand_player_statistics.flg_p_face_raise) and tourney_hand_player_statistics.cnt_p_raise = 0

I think you don't necessarily need them there but, for clarity and safety's sake, I always recommend using them. It just makes it much easier to understand what is going on.
