Holdem Preflop Range Calculator

Formula

The formula to calculate the Hand Strength (HS) is:

\[ \text{HS} = (\text{C1} + \text{C2}) + \text{SB} + \text{PB} - \text{OAP} \]

Where:

\(\text{HS}\) is the hand strength
\(\text{C1}\) is the rank of the first card (2-14, where 14 is Ace)
\(\text{C2}\) is the rank of the second card (2-14, where 14 is Ace)
\(\text{SB}\) is the suit bonus (0 if not suited, 2 if suited)
\(\text{PB}\) is the position bonus (0 if early, 3 if late)
\(\text{OAP}\) is the opponent aggressiveness penalty (0-5)

What is a Holdem Preflop Range?

A Holdem Preflop Range refers to the range of hands that a player is willing to play before the flop in Texas Hold’em poker. This range can vary based on several factors including the player’s position at the table, the actions of other players, and the player’s own strategy. Understanding and calculating the strength of your hand within this range is crucial for making informed decisions during the game. The preflop range helps players determine whether to fold, call, or raise based on the potential strength of their hand relative to the community cards that will be revealed in later rounds.

Example Calculation

Let's assume the following values:

Rank of First Card (C1) = 10
Rank of Second Card (C2) = 12
Suit Bonus (SB) = 2 (suited)
Position Bonus (PB) = 3 (late position)
Opponent Aggressiveness Penalty (OAP) = 1

Using the formula:

\[ \text{HS} = (10 + 12) + 2 + 3 - 1 = 26 \]

The Hand Strength (HS) is 26.
