After fifteen years of playing professionally, I can spot a bad player within five hands. Sometimes within five seconds. It's not about their clothes or their chip tricks or their table talk. It's about patterns—specific behaviors that bad players exhibit consistently because they don't understand why those behaviors cost them money.
I'm about to give you the exact blueprint I use to identify fish at any table. These aren't vague concepts like "plays too many hands." These are specific, exploitable patterns that transform bad players into ATMs. Learn these tells and you'll never wonder who the fish is again.
The Pre-Game Tells (Before Cards Are Even Dealt)
Bad players reveal themselves before playing a single hand. Here's what I look for when someone sits down:
Buying in for weird amounts is instant fish confirmation. Good players buy in for the maximum or a strategic short-stack amount. Fish buy in for $317 because "that's what I have in my pocket" or $150 at a $1/$2 table because they're scared money. Random buy-in amounts indicate no understanding of stack strategy.
The chip arrangement tells you everything. Pros organize chips in standard 20-chip stacks, usually by denomination. Fish have random piles, mixed denominations, or that classic tell—building little chip sculptures while waiting for hands. If someone's making chip pyramids, they're not thinking about poker strategy.
Asking basic rules questions marks instant fish. "What's the blind?" after sitting down. "Is this limit or no-limit?" "Can I raise now?" If they don't know game structure, they definitely don't know advanced strategy. Last week a guy asked me if a flush beats a full house. I almost fell off my chair reaching for chips to get in pots with him.
The way they handle cards physically matters. Pros have economy of motion—quick peek, cards down, decision made. Fish bend cards checking them repeatedly, hold them too high where neighbors might see, or that classic fish move—showing cards to friends behind them. Anyone showing cards to railbirds is hemorrhaging information and money.
The Mathematical Incompetence Tells
Bad players don't understand poker math, and it shows in every decision they make.
Calling without pot odds is the most expensive fish tell. The pot is $50, someone bets $100, and the fish calls with a gutshot straight draw. They're getting 1.5:1 odds on a 10:1 shot. This isn't just bad—it's mathematically illiterate. Yet fish do this constantly because they think "I might hit" is sufficient analysis.
Bet sizing that makes no sense reveals mathematical incompetence. They'll bet $15 into a $200 pot with the nuts, afraid to "scare people off." Or bet $200 into a $30 pot as a bluff, not understanding that they're risking too much to win too little. Good players size bets based on pot geometry. Fish pick random numbers.
Not understanding implied odds leads to terrible decisions. A fish will fold getting 5:1 with a flush draw because "I probably won't hit," not realizing the implied odds make calling profitable. Conversely, they'll call huge bets with weak draws because "I'll win a big pot if I hit," not understanding reverse implied odds.
Stack-to-pot ratio blindness is expensive. Fish don't adjust their play based on stack sizes. They'll call a raise with suited connectors when they only have 15 big blinds left. Or they'll fold strong hands in spots where they're pot-committed. If someone doesn't understand SPR, they're bleeding money.
The Strategic Incompetence Patterns
These are the strategic mistakes that separate fish from competent players:
Playing out of position constantly is suicide in poker, but fish don't understand positional advantage. They'll call raises from early position with marginal hands. They'll flat call on the button with premium hands, wasting their positional advantage. Watch for players who seem position-agnostic—they're gold mines.
Never adjusting to opponents is a massive leak. A good player notices that you're tight and starts attacking your blinds. A fish keeps folding. A good player recognizes a maniac and tightens up. A fish keeps calling with marginal hands. The inability to adjust strategy based on opponent tendencies is dead money walking.
Transparent betting patterns make fish easy to play against. They bet big with big hands, small with draws, and check when they miss. It's like playing with their cards face-up. I played with a guy who literally only raised with AA, KK, or AK. Everyone knew it. He couldn't understand why he never got action on his premium hands.
Defending blinds incorrectly is expensive. Fish either defend too wide ("It's my blind!") or never defend at all. They don't understand that blind defense depends on the raiser's position, sizing, and tendencies. They treat blind defense as all-or-nothing rather than a nuanced decision.
The Emotional Control Failures
Fish can't control their emotions, and emotional players are profitable players (for everyone else):
Visible tilt is ATM mode. They start playing every hand after a bad beat. Raising with garbage. Calling with nothing. When someone starts playing 80% of hands and betting wildly, that's not poker anymore—it's charity. I've seen players lose $5,000 in an hour on pure tilt that started from losing a $200 pot.
Results-oriented thinking reveals fish mentality. They'll say things like "I can't believe he called with that and won!" or "I played it perfectly and still lost!" Good players understand variance. Fish think every loss is either bad luck or conspiracy. If someone's constantly complaining about luck, they don't understand poker.
Emotional bet sizing tells you their mental state. Angry bets are bigger. Scared bets are smaller. When tilted, fish either min-bet (scared of losing more) or overbet wildly (trying to win it all back). Their emotional state leaks into their betting patterns like water through a sieve.
Revenge poker is profitable to play against. A fish loses a big pot to seat 4, then starts targeting seat 4 specifically. Playing personal vendettas instead of optimal strategy. I love when fish declare war on specific players—they make terrible decisions trying to "get even" with someone who's just playing poker.
The Timing Tells That Never Lie
The speed of decisions reveals player quality with shocking accuracy:
Instant calls with draws indicate fish. Good players consider pot odds, implied odds, and fold equity before calling with draws. Fish see four cards to a flush and instantly call any bet. That immediate call with a drawing hand means they're not calculating anything—just hoping.
Hollywooding with obvious decisions marks amateur hour. Taking two minutes to fold 7-2 offsuit preflop. Acting tortured before calling with the nuts. Good players act quickly with clear decisions and take time with close ones. Fish do the opposite—they Hollywood garbage and snap-decide tough spots.
Inconsistent timing patterns reveal hand strength. Fast bet = strong. Long tank then bet = bluff. Same timing every decision = trying not to give away information but actually giving away everything. Fish haven't learned to balance their timing, making them readable.
The "fake think" is hilariously transparent. They'll pretend to consider before making an obvious decision. Tank for thirty seconds then fold to a min-bet. Pretend to count chips before checking. It's theater, and bad theater at that.
The Verbal Diarrhea Syndrome
Fish talk too much, and every word costs them money:
Explaining their strategy while playing is insane but common. "I'm only playing premium hands tonight." "I never bluff." "I always chase flushes." They're literally telling you how to beat them. It's like a boxer announcing where he's going to punch next.
Discussing hands during play is fish behavior. "Did you have aces?" while the hand is still going. "I think you're bluffing" to gauge reactions. Good players shut up and play. Fish narrate their thought process and beg for information.
Bad beat stories mark fish immediately. Nobody cares about the time your aces got cracked six months ago. Good players understand variance and move on. Fish need therapy sessions about every loss. If someone starts telling bad beat stories, they're emotionally vulnerable and probably bad at poker.
Teaching at the table is negative EV stupidity. A fish makes a bad call, wins, and someone explains why it was bad. Why are you educating your opponents? Let them make mistakes. But fish can't help themselves—they need to prove they know poker theory even while losing money.
The Physical Tells That Cost Fortunes
Body language doesn't lie, and fish have no body control:
Posture changes with hand strength. Slouching with garbage, sitting up with monsters. It's unconscious and consistent. I watched a guy literally lean forward every time he had a strong hand. He might as well have announced his holdings.
Breathing patterns reveal everything. Shallow breathing with big hands (trying to stay calm). Deep breathing with bluffs (needing oxygen for stress). Fish don't even know they're doing it. One player I knew held his breath when bluffing. He'd literally turn red. Free money.
Chip handling tells stories. Shuffling chips nervously when weak. Stacking them neatly when strong. Grabbing chips before their turn when they're going to bet. Pulling chips back when they're going to fold. Fish telegraph their intentions constantly.
Eye contact patterns are reliable. Staring at opponents when bluffing (trying to look strong). Avoiding eye contact when value betting (trying not to scare anyone). Fish haven't learned to control their gaze, making them transparent.
Playing Against Fish on Your Poker Table
Once you've identified the fish, here's how to extract maximum value:
Value bet relentlessly. Fish call too much, so bet your good hands larger and more frequently than against good players. They'll call with second pair, any draw, or sometimes just because they're curious. Thin value bets that would be terrible against good players print money against fish.
Avoid fancy plays. Fish don't fold when they should and don't understand what you're representing. That sophisticated triple-barrel bluff? They'll call with bottom pair. Keep it simple: bet when you have it, fold when you don't.
Isolate them constantly. When a fish limps, raise to isolate them. You want to play pots heads-up against bad players, not multiway where variance increases. If a fish is in the pot, you should be looking for reasons to play, not fold.
Let them hang themselves. Fish bluff too much and at the wrong times. Give them rope. Check strong hands and let them bluff. Call down lighter than usual. They'll put money in with garbage if you just give them the opportunity.
Never educate them. When they make terrible plays, say "nice hand" and move on. Don't explain their mistakes. Don't discuss strategy. Let them keep bleeding money. Your home game profits depend on fish staying fishy.
The Levels of Bad Players
Not all fish are equal. Understanding the hierarchy helps you adjust exploitation strategies:
Level 0: Complete Beginners. Don't know rules, hand rankings, or basic strategy. Exploit by value betting everything and never bluffing. They'll call with anything.
Level 1: Bad Recreationals. Know the rules but not strategy. Play too many hands, call too much, sized bets randomly. Exploit with value betting and positional advantage.
Level 2: Wannabe Pros. Learned some strategy but apply it incorrectly. They know about position but still call out of position. They know about pot odds but calculate them wrong. Exploit their incomplete knowledge by putting them in complex situations.
Level 3: Tilted Regs. Usually decent but emotionally compromised. After losses, they transform into Level 1 fish. Exploit by triggering tilt then value betting their emotional spillage.
Each level requires different exploitation, but they're all profitable. The key is recognizing which type of fish you're facing and adjusting accordingly.
The Bottom Line
Spotting bad players isn't about one tell—it's about patterns. The player who exhibits multiple indicators isn't just having a bad day; they're fundamentally bad at poker. And in poker, bad players are the entire economy.
Without fish, poker doesn't exist. They fund the ecosystem. So while you should ruthlessly exploit their mistakes at the table, always be respectful and welcoming. A happy fish keeps playing. An insulted fish leaves and never comes back.
Learn these patterns, practice spotting them quickly, and your win rate will skyrocket. Every table has at least one fish. If you can't spot them using these tells, well... you know what that means.
