I am trying to create some custom stats. And I have problems with this column (flg_f_has_position).
Can u explain to me how it works. Why in the the following hand PT(stat reflecting column "flg_f_has_position") shows that I have NO position on flop.

Hand #616785307 begins at 2007/08/03

There is a bug in flg_f_has_position at the moment. This will be fixed, but please attach your original hand history for that hand to the Support system , and link to this thread.
