Ever wondered how poker pros make those tough decisions? A big part of their strategy is knowing their "outs" and how they affect the odds of winning. Let's break it down in simple terms so you can use this in your next game!

What Are "Outs" in Poker?

Outs are your potential winning cards

Definition: An "out" is any unseen card that, if drawn, will improve your hand to potentially win.
How to Find Them: Look at your hand and the community cards to figure out which cards remaining in the deck can help you.

Example:

5♠

6♠

7♣

8♥

K♦

You need a 4 or a 9 to make a straight (a sequence of five cards in order).

Counting Your Outs:

There are four 4s and four 9s in the deck.
So, you have 8 outs (4 + 4).

Estimating Your Chances with the "Rule of 4 and 2"

This rule helps you quickly calculate the odds of hitting one of your outs.

1. After the Flop (Two Cards to Come)

Multiply your outs by 4.

Why? Because you have two more chances (the turn and the river) to get your card.

Using Our Example:

Outs: 8
Calculation: 8 outs × 4 = 32% chance to make your straight by the river.

2. After the Turn (One Card to Come)

Multiply your outs by 2.

Why? Only one card (the river) is left to be revealed.

If You Didn't Hit on the Turn:

Outs: 8
Calculation: 8 outs × 2 = 16% chance to make your straight on the river.

Quick Tip

Each out is roughly a 4% chance after the flop and a 2% chance after the turn.

Making Smart Decisions: Comparing to Pot Odds

Knowing your outs is half the battle. The other half is deciding whether it's worth continuing in the hand based on the pot odds.

What Are Pot Odds?

Definition: The ratio of the current pot size to the cost of your next call.
Purpose: Helps you decide if the potential reward justifies the risk.

Example:

The pot is $90.
Your opponent bets $10.
So, the total pot is now $100, and it costs you $10 to call.

Calculating Pot Odds:

Pot Odds Ratio: $100 (pot) ÷ $10 (call) = 10 to 1.

Should You Call?

Your Chance of Winning: 32% (from earlier calculation).
Converting Odds to a Ratio: 32% chance is roughly 2 to 1 odds against hitting your hand.
Decision: Since the pot odds (10 to 1) are better than your odds of winning (2 to 1), it's a good idea to call.

Putting It All Together: A Step-by-Step Guide

Step 1: Count Your Outs

Identify the cards that will improve your hand.

Example: 8 outs for a straight draw.

Step 2: Use the Rule of 4 and 2

Multiply by 4 after the flop or 2 after the turn.

Example: Next card is flop -> 8 outs × 4 = 32% chance (~2:1). Next card is river -> 8 outs × 2 = 16% chance. (~5:1)

Step 3: Calculate Pot Odds

Divide the total pot by the cost to call.

Example: $100 pot ÷ $10 call = 10 to 1 pot odds (~9%).

Step 4: Make Your Decision

If your chance of winning is better than the pot odds, it's a good call.

Example: 2 to 1 odds against winning is better than 10 to 1 pot odds.

Step	Action	Example
1. Count Your Outs	Identify the cards that will improve your hand.	8 outs for a straight draw.
2. Use the Rule of 4 and 2	Multiply by 4 after the flop or 2 after the turn.	Next card is flop -> 8 outs × 4 = 32% chance (~2:1). Next card is river -> 8 outs × 2 = 16% chance. (~5:1)
3. Calculate Pot Odds	Divide the total pot by the cost to call.	$100 pot ÷ $10 call = 10 to 1 pot odds (~9%).
4. Make Your Decision	If your chance of winning is better than the pot odds, it's a good call.	2 to 1 odds against winning is better than 10 to 1 pot odds.

Why This Makes Sense - The concept of expected win in poker

Your expected win is a statistical concept. This is the chance of winning times the possible money you would win, which in this case is 0.32 × 100$ = 32$. So given these odds mentioned in earlier examples (32% on flop, 16% on river), if you played against it enough times you would on average win 32$. Obviously, betting 10$ to win 32$ each time (on average) is a good idea. For the 16% case, the expected win is then 0.16 × 100$ = 16$ which still makes it a good call.

Break even odds

Your "break even odds" are in this case 10%, so if your chance of winning is 10%, you expect to on average win 10$ which would mean you are "breaking even" and on average earn nothing. This means that if we have 2 outs or less, we should fold given this pot.

Why This Matters

Understanding outs and odds helps you make better decisions:

Confidence at the Table: Knowing the math boosts your decision-making.
Long-Term Success: Making statistically sound choices increases your chances of winning over time.
Enjoyment of the Game: The more you understand, the more fun you have!

Quick Recap

Outs: Cards that can improve your hand.
Rule of 4 and 2: A simple way to estimate your chances.
After the Flop: Outs × 4 = 32% chance to improve by the river.
After the Turn: Outs × 2 = 16% chance to improve on the river.
Pot Odds: Compare them to your winning odds to decide your next move.

Remember

Poker is a game of both skill and chance. By mastering the concept of outs and odds, you're stacking the deck in your favor—even if the cards don't always cooperate!

Good luck at the tables, and may the flop be ever in your favor!
