It's a game of chess according to Cameran Derefield. There's a king and a pawn.  Which is which, welp, that's to be determined at the end of the deer season.  Studying annual journals about buck behavior and with heavy game camera monitoring, Cameran believes that he can see the target buck's next move and plan accordingly.  It's not instant success, but it is methodical and persistent and generally speaking, Cameran is the one calling checkmate.
