What's the difference between a raise and a bet?

A bet is putting chips in when no one else has bet—you're initiating the action. A raise is increasing an existing bet. Both are aggressive actions, but raises specifically respond to previous aggression. Technically, an 'open raise' preflop is the first bet after the blinds, while a '3-bet' is raising that raise.

What is the minimum raise in poker?

The minimum raise must be at least the size of the previous bet or raise. If someone bets $20, your minimum raise is to $40 (the $20 bet plus a $20 raise). If someone raises from $20 to $60 (a $40 increase), your minimum re-raise is to $100 ($60 + $40). No-limit allows any raise up to your entire stack.

What is a 3-bet and 4-bet?

A 3-bet is the third bet in a sequence: blinds (bet 1), open raise (bet 2), re-raise (bet 3—the 3-bet). A 4-bet is raising the 3-bet. These escalating raises typically represent increasingly strong ranges, though modern strategy includes lighter 3-bets and 4-bet bluffs. Understanding 3-bet and 4-bet dynamics is crucial for preflop strategy.

How much should you raise in poker?

Preflop: typically 2.5-3x the big blind, adding 1BB per limper. 3-betting: 3-4x the original raise in position, 4-5x out of position. Postflop: 2.5-3x the bet when raising. The key is consistency—use similar sizes for value and bluffs so opponents can't read your hand strength from sizing. Adjust sizing based on stack depth and opponent tendencies.

Raise

Raising is poker's aggressive power move—the decision to increase stakes, build pots, and force opponents to make difficult decisions. Unlike the passive call, a raise takes control: you're defining the price others must pay to continue. Raising accomplishes multiple goals simultaneously: it extracts value from worse hands, denies correct odds to draws, generates fold equity against marginal holdings, and gathers information about opponent strength. The best players understand that poker is largely about aggression—and raising is how you apply it.

What is Raising {#what-is}

Definition

Raising means increasing the current bet amount.

Aspect	What Happens
Your chips	More than current bet
Pot growth	Increases significantly
Opponent options	Fold, call, or re-raise
Action status	Re-opens betting round

Raise vs Other Actions

Action	Effect
Raise	Increase bet, force decision
Bet	Initiate betting (no bet exists)
Call	Match bet, no pressure
Check	Pass without betting
Fold	Give up hand

Raise Terminology

Term	Meaning
Open-raise	First raise preflop
3-bet	Raise over a raise
4-bet	Raise over a 3-bet
Re-raise	Generic term for raising a raise
Check-raise	Check then raise when bet to
Squeeze	3-bet after raise and call(s)

Minimum Raise Rule

\text{Minimum Raise} = \text{Previous Bet} + \text{Size of Previous Raise}

Examples:

Situation	Minimum Raise
BB is $10, UTG raises to $30	$50 ($30 + $20)
Bet is $50, raise to $150	$250 ($150 + $100)
All-in for less than full raise	Doesn't re-open action

When to Raise {#when}

Primary Reasons to Raise

Reason	Explanation
Value	Get worse hands to call
Bluff/Semi-bluff	Get better hands to fold
Protection	Deny drawing odds
Isolation	Get heads-up vs weak player
Information	Learn about opponent's hand
Initiative	Take control of the hand

When to Raise for Value

Your Hand	Board	Why Raise
Top pair top kicker	Most	Get called by worse pairs
Overpair	Low board	Protection + value
Set	Wet board	Charge draws
Nut hand	Various	Build pot

When to Raise as Bluff

Hand	Situation	Why
Missed draw	River	Last chance to win
Air with blockers	Various	Block their value
Semi-bluff (draw)	Flop/Turn	Fold equity + equity

When NOT to Raise

Situation	Why Not
Trapping	Want opponent to keep betting
Way behind	Throwing away money
Multi-way, marginal hand	Someone has it
No fold equity	Calling station
Pot control	Medium strength, keep pot small

Raise Sizing {#sizing}

Preflop Raise Sizing

Situation	Size	Notes
Open-raise	2.5-3x BB	Standard
With limpers	Add 1 BB per limper	Charge more
Short-stacked	Shove or smaller	Depends on strategy
Very deep	Can go larger	3-4x acceptable

Postflop Raise Sizing

Situation	Size	Reason
vs. C-bet	2.5-3x	Standard raise
Check-raise	3-4x	Build pot, deny odds
River raise	2.5-3x+	Polarized (value or bluff)

3-Bet Sizing

Position	Size	Example
In position	3x original raise	Raise $10 → 3-bet $30
Out of position	4x original raise	Raise $10 → 3-bet $40
With callers	Add 1 original raise per caller	Adds dead money

Why Sizing Matters

\text{Larger Raise} = \text{More Fold Equity} + \text{Less Bluff Frequency Needed}

Size	Effect on Opponent
Small	Good pot odds to call
Medium	Standard decision
Large	Pressure, harder call
Overbet	Polarized, max pressure

Consistent Sizing

Key principle: Use same sizing for value and bluffs.

Bad Pattern	What It Reveals
Big = strong	Opponents fold when needed
Small = weak	Opponents attack bluffs
Varying by hand	Exploitable

Types of Raises {#types}

Open-Raise

Definition	First raise preflop
Standard size	2.5-3x BB
Purpose	Build pot, take initiative
Frequency	15-50% by position

Continuation Raise

Definition	Raising opponent's c-bet
When	Strong hand or good bluff
Size	2.5-3x the c-bet
Risk	Committing chips

Check-Raise

Definition	Check then raise when bet to
Purpose	Trap, build pot, semi-bluff
Frequency	8-15% of checks
Strength signal	Very strong (or bluff)

Donk Raise

Definition	Raising after leading out
Example	You bet, they raise, you re-raise
Signal	Very strong usually
Frequency	Rare

Squeeze Play

Definition	3-bet after raise and call(s)

Size	4-5x original raise

3-Betting and 4-Betting {#3bet-4bet}

What is 3-Betting?

Blinds = Bet 1

vs SB	Wide	Very wide

3-Bet Sizing Guide

Your Position	Sizing

For value	QQ+, AK (sometimes)
As bluff	A5s-A2s (blocks AA, AK)
All-in threshold	Often just shove

Sizing	What worse hands call
Frequency	Most of raising range

Bluff Raising

Goal	Get better hands to fold

Value-to-Bluff Ratio

\text{Bluff \%} = \frac{\text{Pot Odds Given}}{\text{1 + Pot Odds}}

Raise Size	Bluff % of Raises
50% pot (creating 1.5:1 odds)	25%
75% pot	30%
100% pot	33%
150% pot	38%

Semi-Bluff Raising

Hand	Why Raise
Flush draw	Fold equity + 35% equity
OESD	Fold equity + 31% equity
Combo draw	50%+ equity, wants to build pot

Semi-Bluff Math

\text{EV} = P(\text{Fold}) \times \text{Pot} + P(\text{Call}) \times (\text{Equity} \times \text{New Pot} - \text{Raise})

Raise Checklist {#checklist}

Before every raise:

Question	Consider
Why am I raising?	Value, bluff, or info
What's calling me?	Worse hands (value) or folds (bluff)
Is my sizing right?	Same for value and bluffs
