Definition
Range polarization is when a player's range contains only very strong hands (value) and very weak hands (bluffs), with no medium-strength hands.
Polarized = Nuts or nothing (no middle)

When Ranges Become Polarized
| Situation | Polarization |
|---|---|
| River betting | Most polarized |
| Large bet sizes | Requires polarization |
| 3-bet pots | More polarized |
| Flop betting | Least polarized |
Polarized vs Capped
| Polarized Player | Capped Player |
|---|---|
| Has nuts in range | No nuts |
| Can bet any size | Limited to smaller bets |
| Can raise | Can't profitably raise |
| Balanced value/bluffs | Only medium hands |
Why Polarize?
| Benefit | Explanation |
|---|---|
| Maximize value | Bet big with nuts |
| Maximize fold equity | Bet big as bluff |
| Put opponent in tough spots | They face big decisions |
| Exploit capped ranges | They can't raise |
Creating a Polarized Range
Step 1: Identify Value Hands
Hands that want calls:
- Sets, straights, flushes
- Strong two pair
- Top pair in some spots
Step 2: Identify Bluffs
Hands that want folds:
- Missed draws
- Hands with blockers
- Zero showdown value
Step 3: Remove Middle
Medium hands check:
- Weak top pair
- Second pair
- Showdown value
Example: River Polarization
Board: K♥ J♣ 4♠ 8♦ 2♣
Your betting range (polarized):
| Value | Bluffs |
|---|---|
| Sets (KK, JJ, 44) | Missed A♥Q♥ |
| Two pair (KJ) | Missed T♥9♥ |
| Straights (if any) | Air with blockers |
Your checking range:
- K-Q, K-T (medium)
- J-T (second pair)
- Underpairs
Bet Sizing with Polarization
| Sizing | Range Shape |
|---|---|
| 25-33% pot | Merged (many hands) |
| 50-66% pot | Somewhat polarized |
| 75-100% pot | Polarized |
| 100%+ pot | Very polarized |
Defending Against Polarized Ranges
| Their Bet | Your Response |
|---|---|
| Large | Use MDF, call with bluff catchers |
| Overbet | Only call with strong hands |
| River | Identify if you beat bluffs |
Key Takeaway
Polarized ranges contain only value hands and bluffs. Polarize when betting large, especially on rivers. Medium hands with showdown value should check. Match your range shape to your bet sizing.
