###### Chapter 3. Entering a pot after raise

In the case where one of the players sitting at the table before us raised, the following key factors will influence our decision:

1. First raiser - First raiser stats - First raiser position
2. Further raisers/callers (if there are any)
3. Table structure
4. Our position and hand

In the general case, the line of reasoning will follow this structure.

First, we need to figure out the range of the player who entered the pot first. A cut-and-dry comparison of our hand with his playing range is not enough. To make the right decision, we have be build as precise a model of our opponent's way of thinking as possible, which is:

1. The way our opponent's range of pre-flop raises depends on his position
2. The way our opponent sees a certain board and plays it
3. Other factors capable of leading to the difference between the opponent's factual range and set in PFR stats
4. His reaction to pre-flop 3-bets

Secondly, using the same method we need to model the ranges of the players who entered the pot after the opponent who bet first.

Thirdly, we will model our opponent's reactions to the different kinds of action, and calculate different decisions profitably. May I remind you that on pre-flop we need to think constantly about how to get to the flop in the most profitable situation that is possible. It is this particular context in which we will analyze the process of decision-making.

We will divide this chapter into sections by the position of the first opponent to enter the pot. As the analysis of this chapter's topic is connected with a very broad variety of situations, we will often fall back to specific cases grouped by this or that parameter.

UTG

Let's say our opponent on UTG enters the pot. We will exclude limp situations for now, as one very seldom meets them on middle and high stakes, and the handling of such actions depends upon player peculiarities that are not described in stats. So, let's say an opponent raised when on UTG.

The classification of playing cases in this situation is as follows:

1. The opponent does not receive an answer; all the players before us fold

1.1. Our position – UTG+1

1.2. Our position – CO

1.3. Our position – BTN

1.4 Our position – SB

1.5. Our position – BB

2. The opponent is called by one of the opponents before us, and the others fold

2.1. Our position – CO

2.2. Our position – BTN

2.3 Our position – SB

2.4. Our position – BB

3. The opponent is called by two opponents before us

3.1. Our position – BTN

3.2. Our position – SB

3.3. Our position – BB

4. The opponent is 3-bet by one other opponent

4.1. Our position – CO

4.2. Our position – BTN

4.3. Our position – SB

4.4. Our position – BB

5. The opponent is called and 3-bet by two opponents

5.1. Our position – BTN

5.2. Our position – SB

5.3. Our position – BB

6. The opponents is 3-bet and called by two opponents

6.1. Our position – BTN

6.2. Our position – SB

6.3. Our position – BB

7. Three players except the opening player entered the pot at once

7.1. Our position – SB

7.2. Our position – BB

Let us analyze all of the cases one by one. As most of them are similar – if not by the results of probability estimation, but by the style of reasoning – the author's speculations will be replaced with problems from real game practice on a number of points.
