Beating Weak Fields: Three Leaks the Whole Pool Shares
Weak fields make mistakes in similar, repeatable directions, which means the profitable plan is targeted exploitation, not balance. Three population leaks cover most of the money.
They are too passive. Small-stakes players do not raise enough and do not bluff enough, and that changes the value of aggression everywhere. Your value bets, thin value bets, and semi-bluffs are all safer than theory assumes, because the raise that punishes them rarely comes. Fast-play your strong hands: slow-playing waits politely for a scare card to kill your action, against opponents who chase draws and refuse to fold top pair anyway. The passivity also carries a warning label. When a passive player's line says "made hand" and they then bet or raise a later street, fold everything decent; this pool essentially never turns a pair with showdown value into a bluff. The one reliable exception: a big brick-river bet after every draw missed, because players who know they cannot win at showdown do find those bluffs. Call wider exactly there.
Their 3-bet ranges are far too strong. The pool skips most of the bluff and thin-value 3-bets it should make, so the 3-bets that do arrive are premium-heavy. Against a range that is aces-and-kings-shaped 90% of the time, defends that a solver approves against a balanced range are simply losing plays, and folding them is the optimal response to the range actually in front of you. Be nitty against 3-bets until an opponent proves wide. Going the other way, punish their trust: they over-fold their wide late-position opens to 3-bets because their fixed idea of "good enough to continue" does not adjust to having opened the button. 3-bet those opens relentlessly with a linear range, everything good, since even decent hands over-perform against a player folding that often.
They do not adjust to context. Five ways to the flop, hands are worth far more and the pool's calling standards barely move, so multiway bluffing is close to lighting money on fire; heads up, those same instincts, calibrated on multiway pots, make them massively over-fold, so attack. And since weak players play worst out of position without the betting lead, isolate them: raise limps and 3-bet opens to buy heads-up pots in position, especially deep, where the edge compounds fastest. Confirming who has which leak is what per-opponent data is for; the Hand Tracker's Players tab turns your own histories into 3-bet, fold, and showdown numbers per villain, and the preflop charts give you the baseline ranges the exploits deviate from.
