It is not enough to define the opponent from the categories of statistics, it is necessary to observe his game and demeanor, and only after that draw conclusions. Players of this style will stubbornly call all your bets to the end, even when they have nothing at all, clinging to the younger pair or weak draw. It makes no sense to
bluff against such players, since they rarely fold, but with a good hand made, you need to constantly bet-raise-reraise, and they often call even bets much larger than the size of the pot itself.
