In other words we will take a shortcut here by estimating our defending frequencies independent of our

**equity**. Finding a correct range construction is immensely more complex than this. As such the strategies outlined in this article can be used as an introduction to

**game theory concepts**– but more knowledge is required to begin solving the game of poker.

## GTO: Break Even Point of a Bluff

**% of total pot invested = % of time bluff needs to work to break even**

**– Villain cbets 7bb into a 10bb pot. How often does his bluff need to work to break even?**

*Example 1***7/17 = 0.412**

**exploiting his opponent**in this instance– and the goal of this article is to prevent him from doing so.

**– Villain cbets 7bb into a 10bb pot. How can we prevent him from generating automatic profit?**

*Example 2***how we defend**(ie raising or just calling)**the board texture**(how harmful is giving free cards)**any inherent range advantage**(the relative equities described in the introduction)

## GTO: Defending on Dry Textures

**- We face a cbet OOP on an A72r board. We decide to check-raise bluff with a decent suited connector and a backdoor draw. What is your initial reaction to this line?**

*Example 3***GTO**point of view. But why?

If we start raising all sets and decent top-pairs for value, our calling range quickly becomes very weak and capped. This is because we had way less decent hands to begin with on a dry texture, and we need to protect all of our weak hands by slowplaying the monsters. On a drawy texture we can still raise a balanced range and have enough decent made hands to protect our calling range.

**Steps:**

- work out villain's
**break even point**on a bluff, and hence how often we need to defend so that we don't give our opponent automatic-profit - calculate
**how many combos**of hands we get to the flop with - work out
**how many total combos**we need to defend - select
**our defending range**from the hands which have the best backdoor potential.

**backdoor flush**draw.

However. seeing as TJs improves on over half the turn cards it's a much better hand to defend. Our turn playability will be significantly higher.

## GTO: Defending on Drawy Textures

**GTO Aggression in Poker**” for more info on calculating this.

From here we can use a process of deduction to calculate how many flatting combos that would leave us. The final step is to decide which hands make the most sense as bluffs and which make the most sense as calls.

**Steps:**

- work out
**villain's break even point**on a bluff, and hence how often we need to defend so that we don't give our opponent automatic-profit - calculate
**how many combos**of hands we get to the flop with - work out
**how many total combos**we need to defend - decide
**which combos**are strong enough to raise for value - decide on a
**bluff:value ratio**and calculate how many bluff combos we will use - calculate
**number of flatting combos**by process of deduction **select flatting range**, followed by bluffing range

## GTO: Inherent Disadvantage

In other words, the idea behind GTO play is not to create an equilibrium in isolated situations but an equilibrium across the entire spectrum of possible scenarios.
