The step from low stakes to $2/$5 is not a step up in difficulty so much as a change in kind. RangeIQ models this pool as structured rather than loose: it folds to continuation bets considerably more than $1/$2 does, and it bluffs roughly twice as often. The recipe that prints at low stakes starts costing money here.
How the $2/$5 pool plays
RangeIQ classes $2/$5 as mid stakes, and the model reflects a pool that has done some work. Calling ranges are tighter, aggression is meaningfully higher, and a continuation bet is far more likely to take the pot down uncontested than it is a level below.
The engine's own read on this stake is that a structured pool makes precise bets more exploitable — meaning your sizing carries more information here, and so does theirs. A bet at $2/$5 is a weaker signal of strength than the same bet at $1/$2.
What that changes in practice
Value-only stops being enough. Against a pool that folds to c-bets far more often, betting only when you are strong makes you readable, and readable is exactly the thing $1/$2 players never got punished for. Your betting range has to contain something other than made hands.
Respect raises again. Turn and river aggression at $2/$5 carries more genuine strength than at low stakes, but it also carries more bluffs than most players adjusting upward expect. The correct response is not blanket caution — it is knowing which opponent type you are facing before the decision arrives.
Size with intent. Because the pool responds to sizing, the same bet does different work depending on how much you make it. Overbets stop being a blunt value tool and start being a way to put a capped range under real pressure.
The most common leak at this level
The leak that defines $2/$5 is arriving with low-stakes habits and no way to tell which ones still apply. Relentless value betting, wide bluff-catching and small-sizing discipline were all correct one level down; some remain correct here and some are now the mistake, and the difference depends entirely on who is across the table.
That is why RangeIQ works from opponent type rather than from a single baseline. The same hand in the same spot produces different recommendations against a Nit, a Calling Station and a Young Aggro, and at $2/$5 you will face all three in the same session.
