when I use two AND, do I need additional brackets or something? or this is enough:
sum( if[tourney_holdem_hand_player_statistics.flg_p_first_raise AND tourney_holdem_hand_player_statistics.flg_p_open
AND tourney_holdem_hand_player_detail.amt_before != tourney_holdem_hand_player_detail.amt_p_raise_made
, (tourney_holdem_hand_player_detail.amt_p_raise_made / tourney_holdem_blinds.amt_bb), 0])
