The issue is that most TAG and Nit players are stuck in the middle – folding too often for their own good. And then eventually they learn how to put those junk hands back into their ranges, at least sometimes, in smart spots to generate extra profit. Then they get punished for that and eventually learn that they need to fold some of those junk hands.
They start as a fish who calls too often and folds too rarely. The average poker player goes through a very similar path of progression. A rare breed of player that folds a correct amount of the time and keeps their continuance frequencies and ranges during a poker hand right on track. But the honest truth is that poker players fall into two main categories:
Your cards hit the muck, you concede the pot to your opponent, and you’re off to the next hand. Folding is the least sexy topic in poker.
