What are exploits in poker and why should you use them?

There are two main approaches to playing poker: a strategy built on GTO (Game Theory Optimal) theory, and exploitative play. While the former assumes balanced decisions against a perfect opponent, the latter is built on taking advantage of your opponents' weaknesses.

An exploit is a deliberate deviation from theoretically optimal play in order to gain an edge against a particular type of player. Simply put, you adjust your strategy to your opponents' mistakes in order to win more.

In this article we will look at exploits that apply to tournament poker (MTT) and specifically to the micro stakes — tournaments with buy-ins up to 10 dollars. It is at these stakes that the share of players making systematic mistakes is the highest, which means the opportunities for exploiting them are at their greatest.

Using exploits lets you increase the profitability of your game, grow your bankroll faster and make better use of your edge against weak opponents. Let's go through the most profitable ones.

Get greedy

At the micro stakes most players tend to call far too often. They hate folding and frequently make decisions out of pure curiosity — they want to "see it through" to the river, even when their hand is clearly not strong enough.

This tendency makes a balanced strategy less effective. Instead of keeping an equilibrium between bluffs and value bets, it is far more profitable to simply bet a lot, and often, whenever you have a good hand.

If you have the edge — bet big. Against players who rarely fold, every bet with a strong hand brings extra profit. Remember that you are playing no-limit hold'em, so the bet size is not capped. With the nuts — the best possible hand — you can move all in on the river and will often get paid. 

This approach significantly increases the overall expected value (EV) of your game: thanks to frequent, large bets, the inflated pots add up to a steady increase in profit over the long run.

Bluff when you cannot win at showdown

At the micro stakes players often tend to overrate the strength of river bets. For all their desire to see every community card, to many of them aggression on the final street in itself looks like a convincing signal of a strong hand. This can and should be used.

If you realise your hand has no chance of winning the pot at showdown, betting as a bluff often becomes the optimal play. In these spots checking leads to a guaranteed loss, while a bet creates scenarios in which your opponent will sometimes throw their cards away. Bluffing in hopeless situations thus recovers part of your losses and turns dead-end spots into potentially profitable ones.

Steal the blinds from late position

At the micro stakes most players do not defend their blinds enough. They call raises preflop too rarely and almost never use 3-bets (re-raises). This creates the opportunity to systematically pick up the blinds without resistance, especially from late position: the cutoff (CO) and the button (BTN).

Since in these positions you act almost last and have the positional advantage, you can enter the pot with a raise, when everyone before you has folded, with a very wide range of hands.

The recommended opening range from the button includes:

• any two suited cards, for example 38 suited;

• any pocket pair, for example 22;

• any ace or king, for example K2 offsuit;

• all broadway combinations (two "picture" cards), for example JQ offsuit.

If the players in the blinds have a passive style (the so-called "nits"), the range can be widened even further — up to any two cards. We covered opponent types in another article — read it to exploit other players' weaknesses even more effectively. 

Regularly stealing the blinds lets you steadily grow your stack without taking the hand to the flop. Over the long run this gives you a tangible edge and helps you withstand the constantly rising blind levels in a tournament. 

Always make a continuation bet in position

If you were the preflop aggressor and are in position, the continuation bet — the c-bet, — should be your standard play. It is one of the basic strategies that generate steady profit at the micro stakes.

The reason is simple: most players miss the flop. The probability that your opponent has connected strongly is very low, so even a small bet puts pressure on them.

The optimal c-bet size is 25–33% of the pot. Such a bet is big enough to force your opponent to fold weak hands, yet optimal for maintaining a good risk-to-reward ratio.

Using the c-bet in position regularly allows you to:

• take down pots without showdown;

• keep the initiative in the hand;

• build the image of an active player, which later helps you extract more value from your strong hands.

It is important, however, not to c-bet automatically. Before deciding, assess the flop texture and your opponent's type. On boards with many possible draws, and against players who don't like folding, this bet can be less effective.

Isolate the limpers

A limp is calling the big blind before the flop. The word limp itself means "feeble" or "weak", which describes the nature of this action perfectly.

At the micro stakes a limp almost always points to a weak starting hand or a passive playing style, instantly marking the limper as a recreational player. These players want to see the flop cheaply without risking a significant part of their chips. Occasionally crafty opponents limp with a strong hand to trap an aggressive player, but such situations are rare.

The most effective response to a limp is an isolation raise (or "iso-raise"). With our raise we aim either to take the chips right there preflop, or to get heads-up in the pot with the recreational player, since it becomes too expensive for everyone else to join the hand. For this purpose, use a raise of 3.5 big blinds plus one big blind for every additional limper.

Players who limp generally defend poorly against pressure. Even if they call the isolation raise, a c-bet on the flop will often decide the hand in your favour. Most passive opponents are simply not prepared to withstand sustained aggression across several streets.

Keep one thing in mind though: if the limper responds to your iso-raise with a re-raise (3-bet), it almost always means a strong hand. In such cases the optimal play is to fold and wait for a more profitable spot.

Conclusion

We have covered the five most profitable exploits at the micro stakes, but the foundation of any exploitative strategy is understanding opponent types. The more precisely you identify a player's behavioural pattern, the easier it is to find and use their vulnerabilities. Some give up too often, some can't stop themselves and bluff too much, some overrate the strength of their hands. Your task is to notice this and adapt your game to the specific opponent. This is exactly the skill that sets a strong, experienced player apart. The article on opponent types can help you with that. Use the typical micro-stakes tendencies correctly, add an understanding of opponent types — and your game will improve dramatically.
