Here are chapters 26–30 of our Easy Game summary:
Chapter 26: Polarization and Responses to 3-Betting
In chapter 26, Andrew Seidman explains how polarization shapes preflop confrontations. A polarized range contains very strong hands and bluffs, excluding medium-strength holdings. A depolarized (strong) range includes strong and medium hands but few bluffs.
Which structure to use depends on how opponents respond to aggression.
Against Bad Players
3-bet primarily for value. Weak opponents call too often and make postflop mistakes, so widening value ranges is profitable. Heavy bluff polarization is unnecessary. Adjust slightly depending on whether they overfold or overcall.
Common OOP Responses to 3-Bets
-
Passive/Bad Response – Calls and plays fit-or-fold.
-
3-bet wider with playable hands.
-
C-bet frequently.
-
-
Tight Response – Folds too much or continues only with premiums.
-
3-bet often.
-
Fold to 4-bets without strong value.
-
Polarization works well here.
-
-
Aggressive Response – Light 4-bets or heavy counterplay.
-
Avoid automatic 3-bets with medium hands.
-
Structure ranges carefully.
-
Medium-strength hands (like AQ in some configurations) may function poorly as 3-bets against tight 4-bettors and instead perform better as flats. Polarization is contextual—not automatic aggression.
The central message: a hand’s strength depends on how opponents respond, not just its raw equity.
Chapter 27: Dealing with Polarized Ranges and Calling Big Bets OOP
In chapter 27, Andrew Seidman explains how to respond to polarized, strong (depolarized), and “everything” ranges.
The Three Range Types
-
Polarized – Premiums and bluffs only.
-
Strong (Depolarized) – Premium and medium-strength hands, few bluffs.
-
Everything – Very wide range, common among loose players.
Correct identification determines optimal response.
Facing a Strong Range
-
Continue only with premiums.
-
Avoid light calls.
-
Consider re-raising selectively if they are slightly too wide.
Strong ranges dominate medium holdings.
Facing a Polarized Range
-
Call more with strong hands.
-
Avoid re-raising value hands unnecessarily.
-
Allow bluffs to continue postflop.
Raising into a polarized range often forces bluffs to fold and isolates you against the top.
Calling Big Bets OOP
Against polarized aggression, hands like AK, QQ, or KK retain strong equity even on unfavorable boards. Flatting can induce further bluffs and maximize value—if the opponent continues aggression. If they shut down postflop unless strong, more direct preflop aggression may be better.
The core principle: avoid 3-bet/folding strong hands against aggressive players. Diagnose range structure before reacting.
Chapter 28: The Range Switch
In chapter 28, Andrew Seidman introduces the “range switch,” a high-level adjustment used only with strong reads.
The problem arises when an opponent correctly adapts to your polarized strategy—refusing to put money in when you are likely strong and attacking when you are likely weak.
The solution: reverse your structure.
-
If you previously raised weak hands and flatted strong ones,
-
Switch to raising strong hands and flatting weaker ones.
This realigns their aggression patterns so they attack into strength and give up against weakness.
However, this adjustment is risky. It only works against disciplined opponents who truly adjust in predictable ways. Without strong evidence, default strategies remain preferable.
The lesson: at high levels, strategies and counter-strategies operate like rock-paper-scissors. Adjust only when confident your opponent has over-adjusted first.
Chapter 29: Hand Categorization, True Hand Values, and Playing Postflop
In chapter 29, Andrew Seidman revisits hand categorization and emphasizes that true value is contextual.
He defines three categories:
-
Premium Value – Strong enough to commit stacks.
-
Medium Value – Strong but not stack-off worthy.
-
Low Value – Not worth continuing passively but viable as a bluff.
True hand value depends on:
-
Card strength.
-
Skill advantage.
-
Position.
-
Table dynamics.
-
Image.
Hands shift categories as board texture and opponent tendencies change.
Raising medium-value hands unnecessarily often destroys implied odds. Sometimes floating preserves more EV than raising.
Bluff selection also matters—hands with overcards or backdoors make better bluff candidates than pure air.
The key insight: hand strength is dynamic and must be re-evaluated on every street.
Chapter 30: The Great Debate… Bet or Check?
In chapter 30, Andrew Seidman analyzes whether to continuation bet medium-strength hands in position against aggressive opponents.
The Case for Checking
Pros:
-
Realize equity.
-
Induce bluffs.
-
Avoid check-raises.
Cons:
-
Allow free cards.
-
Miss value.
-
Risk becoming range-transparent.
The Case for Betting (Seidman’s Preference)
Pros:
-
Deny equity.
-
Maintain initiative.
-
Induce light check-raises.
-
Keep range merged and harder to read.
Betting reframes value: a bet can profit from worse raises, not just worse calls.
Checking requires balancing ranges and sometimes sacrificing immediate EV for long-term concealment. Seidman prefers taking immediate positive expectation and adjusting if aggression arises.
Checking makes sense mainly when opponents check-raise excessively and your hand lacks sufficient equity to continue.
The broader conclusion: betting simplifies strategy, maintains pressure, and prevents opponents from exploiting predictable checking patterns.
