How to exploit fish: beat the player, not just the solver.

🐟 Calling station

Calls too much, rarely folds a pair, rarely raises without it.

• Iso-raise their limps big: 5–6bb + 1bb per limper — they call anyway.
• Value 3-bet wider (TT+, AJ+, KQ) — they call 3-bets with worse. No light 3-bet bluffs.

• Value bet thin and big, three streets: top pair good kicker is a 3-street hand.
• Size up with the nuts — overbet or jam rivers; they pay.
• Their raises are strong — fold one-pair hands to a raise.

• Bluffing, semi-bluffing without real equity, and "representing" scary cards — they don’t fold.

The three rules

• Value bet thinner. Top pair with a weak kicker, even second pair on a dry board, becomes a bet.
• Bet bigger. They call anyway, so charge them. Overbet when you've got the nuts.
• Stop bluffing. A bluff only works if they fold. They don't.

And when a station suddenly raises? Believe it.

🎲 Passive rec

Plays too many hands, mostly passively; folds when they miss.

• Iso-raise their limps (4–5bb + 1bb per limper), in position when you can.
• Widen your value range vs their opens and limps; tighten your bluffs.

• C-bet a lot heads-up — many recs fold to c-bets 55%+ (check their stats).
• When they call twice, give them a hand: value bet, stop bluffing.
• Sudden big bets or raises from a passive player are strong.

• Fancy lines and multi-street bluffs against a player who has already called twice.

🔥 Maniac

Hyper-aggressive: big bets and shoves with air.

• Tighten your opens; 3-bet or 4-bet for value and get it in with QQ+/AK (JJ, AQs too).
• Call their shoves much wider than vs anyone else.

• Let them bluff: check strong hands to them, call down with top pair+.
• Avoid building pots with marginal hands out of position.

• Bluffing, and folding strong one-pair hands to their big bets.

🐋 Loose-aggressive whale

Loose AND aggressive: bets and raises with a wide, weak range.

• Tighten up and value 3-bet (JJ+, AQ+, KQs) — they give action with worse.
• Don’t open trash in front of them — they iso and 3-bet a lot.

• Check to them more with strong hands and let them bet (check-call or check-raise).
• Call down lighter — top pair and good second pair go further.
• Bet big for value when you are ahead; they call wide.

• Bluffing into them — they call and raise too often.

🪨 Nit

Very tight and passive.

• Steal their blinds relentlessly; fold to their 3-bets unless you have a premium.

• C-bet and barrel — they fold a lot.
• When they bet or raise, believe them.

• Paying off their big bets with one pair.

📊 Solid reg

Solid, aggressive regular — fewer mistakes, so exploit their stats, not their "type".

• Check their fold-to-3-bet: if high (45%+), 3-bet them more as bluffs; if low, value 3-bet only.
• Vs a high 3-bettor (10%+), 4-bet value wider and flat their 3-bets in position.
• Defend your blinds vs their steals; 3-bet them light when they steal 40%+.

• If they c-bet a lot but fold to raises, float in position and raise dry boards.
• Respect river raises — regs rarely bluff-raise rivers at these stakes.

• Tangling out of position with marginal hands; spewy bluffs they’re good enough to catch.

📋 Weak reg

Knows the basics, plays a fit-or-fold, predictable game.

• Steal their blinds and 3-bet their late-position opens.

• Barrel scare cards — they over-fold turns and rivers.
• Their big lines are strong; fold medium hands to them.

• Paying off their river raises.
