Expected Value (EV) Numbers

The idea EV = (P1 × O1) + (P2 × O2) helps figure out the long-term worth of each poker choice. Keep track of all possible results and their chance to find the best plays.

Chance of Drawing Cards with Rules of 2 and 4

Drawing odds use the key Rule of 2 and 4. Multiply the cards that can help by 2 for one more card’s odds and by 4 for two more cards. This fast math helps you see your chances quickly during a game.

Using Position in Math

The position formula PA = n/p shows the edge you get by acting last. Being late in the turn order gives more info and control, so your choices can have a better expected value.

Keeping Your Money Safe with Numbers

Use the Kelly Criterion and other stats ideas to manage your poker cash well. This math helps keep your money safe and grow it with less risk over time.

Pot Odds and Equity Basics

What are Pot Odds and Equity in Poker?

Basics in Poker Math

Pot odds and equity are the basic numbers for great poker choices. These ideas help players make moves that make the most sense math-wise.

Figuring Out Pot Odds

Pot odds show the math link between the bet you need to call and the total pot after your call. To find pot odds, you divide your call cost by the total pot. Like calling $20 into a $100 pot gives odds of 20/120 = 16.7%.

Using Hand Equity

Hand equity shows your win chance as a percent. Players figure this by:

Counting cards that help the hand (“outs”)

Multiplying outs by 2% after the flop

Multiplying outs by 4% on the turn

For example, a flush draw with 9 outs gives about 18% equity on the turn.

Making Moves that Earn

Using Math to Decide

Compare hand equity with pot odds. If equity is higher than pot odds, then calling or raising makes sense. Look at this:

Hand equity: 18% (flush draw)

Pot odds needed: 16.7%

Result: It pays to call here

This math helps in deciding to fold, call, or raise based on numbers.

How to Think About Expected Value

Getting the Most from Expected Value (EV) in Poker

Basic EV Rules

Expected value is the average result of any poker choice over time. You need to master EV numbers by looking at possible results and their chances.

Simple EV Math

The basic EV math goes: EV = (Chance of Winning × Money Won) – (Chance of Losing × Money Lost)

Real EV Example

Imagine a pot of $150 and a bet of $50:

Win chance: 30%

Win money: $150

Lose chance: 70%

Lose money: $50

EV Work: (0.30 × $150) – (0.70 × $50) = $45 – $35 = $10 good EV

Advanced EV Tips

Handling Many Outcomes

For hard choices with many results, use: EV = (P1 × O1) + (P2 × O2) + (P3 × O3)

P is chance

O is money in results

Making Choices Using Math

EV numbers guide smart choices in:

How much to bet

When to play based on position

Analyzing the board cards

Figuring Out Drawing Chances in Poker

Mastering Drawing Hand Chances in Poker

Learning About Outs and Drawing Odds

The start of working out drawing hand chances is knowing outs – the cards that boost your hand. This guide looks at tested ways to know your chances of getting winning hands.

Fast Rules of 2 and 4

Quick Math for Odds:

Rule of 4: Multiply outs by 4 for river odds from the flop

Rule of 2: Multiply outs by 2 for turn odds from the flop

Example Math

A flush draw with 9 outs shows:

36% chance (9 x 4) to complete by the river

18% chance (9 x 2) to hit on the turn

Exact Math for Drawing

For exact odds math, use: ‘P(hitting) = 1 – (C(47-n,r)/C(47,r))’

n = outs

r = cards left to deal

Linking Pot Odds with Drawing Odds

Smart Moves:

Work out drawing odds

Match with pot odds

Find plays with good expected value

Call when drawing odds beat pot odds

Knowing Your Spot and Math in Poker

Getting the Edge with Poker Position Math

Key Ideas on Position Edge

Position math is vital for smart poker plays. The key positional edge (PA) math is PA = n/p, where ‘n’ is players left and ‘p’ shows your spot relative to the button.

How Position Changes Things

Early Spot Challenge

Playing early means (n-1) unknown moves, adding a big unknown factor. This math challenge means you need to think well about pot and implied odds.

Late Spot Wins

Late spot plays give the most info as (n-1) moves are known, cutting down on guesswork in value math. This info lead turns into more chances to make money.

Deep Dive into Position Math

The full position edge from math can show as: E(pos) = (Σvi * pi) * PA

vi = worth of each move

pi = chance of each move

PA = position edge multiplier

The Button Strategy

Button spot uses full info for max E(pos). The position boost (PM) math, PM = 1 + PA, changes usual pot odds to show real math edges. Smart play means using base odds times PM to find true math edges every hand.

Keeping Money Safe with Stats

Stats for Managing Money

Stat money care uses exact numbers to keep and grow cash in betting and trading. The base lies in figuring needed money using usual win rate swings (?) and how much risk you can take (α) to keep doing well.

Cash Game Money Math

The must-have formula for cash games is: Needed Money = (Z-score × ? × √N) + (Expected Loss × N)

Where:

N is all game sessions

maximize profits

Z-score at 95% sure level is 1.96

Suggested save: 20-25 buys per stake level

Tourney Money Math

Tourney players need to think of bigger swings using: Lowest Money = (Usual Buy-in × ROI × K)

Main points:

K is risk boost based on ROI swings

MTT boost (K=100)

SNG boost (K=50)

Using Kelly Math Right

The Kelly Math sets bet sizes: Best Bet Size = (bp – q) / b
