What is a Fish in Poker

Introduction

Playing Poker successfully requires a combination of skill, strategy and psychology. Of the different players you may come across at the table, none are more discussed than those known as fish. Knowing how to recognize and compete against these opponents can significantly enhance your overall performance in the game. Let's understand the Poker fish definition, the characteristics of a fish player and strategies to exploit their weaknesses.

Who is a Fish in Poker?

The poker game has a slang term,' fish', which refers to inexperienced, unskilled or inadequate players. Such participants are prone to making repetitive mistakes such as calling too often, playing weak hands excessively and lacking comprehension of fundamental poker strategies - which makes them easy targets for exploitation.

Examples of fish used in a sentence

• A fish would hesitate to raise with Pocket Aces in the pre-flop.
• A player is a fish if he does not play according to positions.
• This player seems like a fish as he goes all-in pre-flop with pocket twos.
• I avoid playing with fish as their gameplay is unpredictable.

How to Spot a Poker Fish

Spotting a fish at the game table is crucial for maximizing your profits. Here are the behaviours to look for when identifying a fish poker player.

Betting Patterns

• Irregular Bets: Fish players often make inconsistent bet sizes. They may bet too much or too little without a clear strategy, such as overbetting with weak hands or underbetting with strong hands.
• Limping: Frequently calling the big blind instead of raising when entering a pot, especially pre-flop, is a common trait. Limping is generally considered a weak move.
• Calling Stations: Fish tend to call bets rather than raise or fold. They often chase draws or call down with marginal hands.

Starting Hand Selection

• Playing Too Many Hands: A fish Poker player is likely to play a wide range of hands, including those considered weak or marginal. They do not understand the importance of starting hand selection.
• Playing Out of Position: They might play too many hands from early positions, not understanding the disadvantage of acting first post-flop.

Lack of Strategy

• No Adjustments: Fish players do not adjust their play based on opponents’ behaviour. They stick to the same strategy regardless of the situation.
• Predictable Play: Their actions are often easy to predict. For example, they might only bet big when they have a strong hand and check or call with weaker hands.

Post-Flop Play

• Chasing Draws: Fish often chase flush or straight draws, even when the pot odds do not justify it.
• Overvaluing Hands: They tend to overvalue one-pair hands or top pair, making large bets or calls with hands that are easily beaten by stronger combinations.
• Fear of Folding: They rarely fold to continuation bets and often stay in the hand until the river, hoping to improve their hand.

Behavioral Tells

• Nervousness or Insecurity: Fish players might exhibit physical tells like shaky hands, looking at their chips nervously, or taking a long time to act.
• Chat and Reactions: They might chat a lot at the table, complaining about bad beats or getting excited when they win a hand. Their emotional reactions are often stronger and more visible.

Bankroll Management

• Inadequate Bankroll: Fish often do not understand proper bankroll management and might play at stakes that are too high for their skill level or financial situation.
• Frequent Rebuys: They may have to rebuy frequently, indicating they lose chips quickly and consistently.

Online Poker Fish

• Timing Tells: In online poker, a fish might take too long to act on simple decisions or act very quickly on complex ones, indicating a lack of thought process.
• Screen Names: In some cases, novice players might choose playful or amateurish screen names, which can be a subtle indicator.

How to Play Against a Fish

Here are detailed strategies to compete against a fish player -

Isolate the Fish

• Aggressive Pre-Flop Raises: When a fish limps into the pot, raise with a wide range of hands to isolate them. This forces them to play heads-up against you, where their weaknesses are more exploitable.
• Position Advantage: Try to get into pots with a positional advantage over the fish. This means acting after them in the betting rounds, which allows you to make more informed decisions based on their actions.

Adjust Your Betting Strategy

• Value Betting: Fish players tend to call with weaker hands. Increase the size and frequency of your value bets to extract maximum value when you have a strong hand. Do not be afraid to make larger bets if you believe they will call with worse hands.
• Avoid Bluffing: Reduce your bluffing frequency since fish are more likely to call with weak holdings. Focus on building pots with strong hands rather than trying to bluff them out.

Pre-Flop Play

• Tighten Up Against Raises: While you want to isolate a Poker fish, be cautious about playing marginal hands if they start raising. Fish players often do not raise lightly, so their raises can indicate stronger hands.
• Widen Your Range: Against a fish who limps often, you can play a wider range of hands, especially when in position. Hands like suited connectors and Broadway cards can be profitable against a fish.

Post-Flop Play

• Play Straightforward: Fish players often do not pay attention to strategies. Play straightforwardly by betting your strong hands and checking your weak ones. This makes your play more predictable and capitalizes on their inability to adjust.
• Exploit Calling Tendencies: Continuously bet for value when you believe you have the best hand. Fish will often call down with second-best hands, allowing you to build bigger pots and extract more value.

Exploiting Weaknesses

• Chasing Draws: When you suspect a fish is on a draw, adjust your bet sizing to make their drawing odds unfavourable. They often call regardless, which means you profit from their mistakes.
• Overvaluing Hands: Recognise when a fish overvalues hands, such as a top pair or weak two-pair. You can make larger bets or even overbet the pot, as they are likely to call with these holdings.

Bankroll Management and Psychology

• Stay Patient: Fish will have up-and-down swings. Wait for good opportunities to exploit their mistakes rather than force them to take action.
• Tilt Avoidance: Fish can occasionally get lucky and win big pots. Do not let this affect your play. Stay focused on the long-term goal of profiting from their overall poor play.

Adjusting to Different Fish Types

• Calling Stations: These players call frequently but rarely raise. Against them, prioritize value betting and avoid bluffing.
• Passive Players: Fish who play passively and rarely bet or raise should be exploited by betting aggressively when you have a strong hand.
• Aggressive Fish: Some fish are overly aggressive and will bet and raise frequently. Adopt a passive strategy against these players by calling with strong hands and letting them bet into you.

Handling Multi-Way Pots

• Narrow Your Range: In multi-way pots with a fish, narrow your hand range to stronger holdings. This is because weaker hands have lower equity in multi-way scenarios.
• Target the Fish: Focus on playing pots where the fish is involved. This increases your expected value since their mistakes will benefit you more than other competent players.

Fish vs Donkey - What's the Difference?

There is not much difference between Fish and Donkey in poker. While both fish and donkey players can be profitable to play against, understanding the differences in their behaviours can help players tailor their strategies effectively. Recognizing these player types can significantly enhance your overall game.

• Both fish and donkeys are unskilled players. A fish is more about being an inexperienced player, while donkeys lack logic or strategic thinking and act abruptly. 

• A fish is considered an unskilled or inexperienced player who finds difficulty understanding the game's basic strategies. They tend to make the same mistakes repeatedly and are exploited by their fellow players. A donkey is also as inexperienced and unskilled as a fish, but they are too unpredictable while playing and are poor at decision-making. They play randomly, and their actions are not backed by strategy or logic.

• A fish might make irregular bets, play too many hands, limps often, and cannot adapt their game based on their opponent’s actions and the situation. A donkey might play weak hands, indulge in extreme bluffing, or chase draws without considering pot odds. 

How do you Stop Being a Fish in Poker?

Stop being a fish is not something you can learn in a day. It takes time and effort to understand and learn the basics of the game, and practice playing poker diligently is the key. Here are some of the essential tips you can adapt to improve your gameplay:

• Learn preflop ranges:

If you lose the game often and want to improve your gameplay, you should start working on the basics of the game. You can begin by understanding the opening hand ranges. You should study and learn which hands to raise preflop from every position at the poker table. Sometimes, even experienced poker players have no clue they are playing the wrong hand from a particular position. So, studying the GTO raise charts is essential to correct yourself and get better at the game. Learning your preflop hand ranges can be a great start to building a solid foundation.

• Don't chase Draws:

A draw means you wait for specific cards in the later rounds to make a straight or flush, as both are strong hands and hitting either one of them means winning the pot. This is where a fish player makes the mistake of going badly after a draw and even calling the bets when they have a weak hand, like a lower pair or even a high card. You should not consider folding your draws every time, but it is necessary to understand the situations in which it is better to fold. 

Although flushes and straights can often lead to bigger pots, especially if your opponent is willing to bet heavily despite having a weak hand, this confidence can lead to larger bets, and if you play it right, you can capitalize on that by extracting more value from the pot.

Due to this reason, at times, fishes go to any lengths hoping to draw a straight or flush even in the turn and river streets with almost negligible equity hands like a weak pair or even when they don’t have any other hand.

Equation to calculate your equity on the flop

Number of Outs x 4 = approximate equity (%)

Equation to calculate your equity on the turn

Number of Outs x 2 = approximate equity (%)

Here, the term “out” means the number of cards that, if opened up, can complete your draw or help you make a strong hand, like straight or flush, especially in turn and river rounds.

Example: Say you have a heart flush getting drawn in the flop. So, say you have K♥7♥ as hole cards, and the community cards in the flop are  9♥6♥10♣. To complete this flush, the remaining 9 cards out of the total 13 cards can act as ‘out’ in this case. Hence, the equity during the flop can be calculated as 36% (4 times the 9 outs). Now, if against a raise, if you have to put less than 36% of the total pot value, then it is a positive Equity value to call against this raise. Thus, calling to complete your flush is the best line to play.

• Be More Critical of Your Game

Poker is a game where you must keep your ego outside the room. A mistake that common players make and successful players don’t make is that successful players analyse their gameplay very carefully. 

Let’s say you get beaten by your opponent in the river round, even when you were the table favourites till the turn round. Then suddenly, in the river round, the other player hits one out of the park and beats you in a showdown. Then, is it solely luck that has made you lose? If it is in this case, let’s just accept it. But what successful players don’t do is that they don’t make it a practice to blame it on luck whenever they come under similar circumstances. They would try to find mistakes in their gameplay in earlier rounds, like pre-flop or during flop and turn to see what they can improve to avoid repeating such instances. On the other hand, fish and donkeys will always try to put it on luck or on to something else to keep their egos satisfied, which keeps them quite far from being profitable.

• Get your Raise Sizes Right

Getting the raises correct can help you graduate from a fish to a profitable player category. It is intriguing to know that even players who have been playing for years sometimes make incorrect raise decisions. 

The point is when you raise too much with a very strong hand, you might lose out on extracting value. On the other hand, while bluffing, if you fail to raise enough, then you are making it too easy for your opponents to call your raises. 

Along with knowing when to raise money, it is also essential to understand why you are raising money. It may seem obvious, but fishes raise without knowing whether they are bluffing or going for value extraction. Assessing your hand in relation to what you think your opponent might have becomes crucial at this juncture. To assess your opponent's hands correctly, the knowledge of hand ranges comes into play.

For example, if an opponent who is quite cautious goes all-in preflop, this means that either they have strong hands or they are bluffing. Now, if you also hold a strong hand on the flop like a Three-of-a-Kind, then it 

is wise to bet big for value in the flop since your opponent will likely continue playing with their probable strong hand.

In contrast, if your opponent at Big Blind just calls with a small raise, then they likely have a weaker hand, and their hand range will be much broader. In this case, if you raise heavily, there are fewer chances that your big bet will be called. Here, a smaller bet can be more effective in extracting value from these weaker hands.

These small decisions can make a big difference in your poker game.
