Overall You suppose to bet range on boards where u have range advatage and u have a lot nuts compare to viallain becouse hes capped for example u open from BTN And BB call board AKx BB not have AA,KK, AK even AQ,AJ so your range crushig him , or on a boards which or very dry like A49r, hard to hit something on this flop and u not need bet high in order to fold hands which completly missed. But what's is the best is this strategy is that your gameplay is very easy u just bet 1/3 very cheap bet. But when You bet this sizing u force on your opponent do defende with rights frequency. He has to call a lot, cant over fold becouse You will have auto profit, he has to check raise right frequency to fold You from equity etc. And most of the players especially lower stakes over fold to c bets and not check raise enough so youu will realize more equity than u supposed. but on the other hand he cant ddefend too much for example on this AKx board becouse he will get owned by youur range if he will defend crapy hands. Overall strategy is simple easy and Your force opponent to create new strategy which is not that easy. Also You can see that a lot players bet range on boards which they not supposed to even by high stakes players becouse its very hard strategy to Play against but its easy by you.
