In chapter 23 of The Theory of Poker, David Sklansky explores the psychology of poker as the skill of thinking about what your opponents think — and what they think you think — so you can make better strategic decisions, not just flashy mind games.
Psychology vs. “Table Talk” Tricks
Sklansky starts by distinguishing:
-
Psychological ploys: needling, trash talk, confusing chatter, theatrics.
-
Used in many games and sports to put people on tilt.
-
They can matter, but they’re generic competition tactics.
-
-
The psychology of poker (in Sklansky’s sense):
-
Understanding how your opponents think about:
-
Their own hands,
-
Your hand,
-
And what you think they have.
-
-
This is deeply tied to:
-
Reading hands, and
-
Using deception effectively in your own play.
-
-
The chapter is about this second, more subtle kind of psychology.
Levels of Thinking in Poker
Sklansky breaks down multi-level thinking with examples:
-
First level – What do they have?
-
Second level – What do they think I have?
-
Third level – What do they think I think they have?
Good psychological plays come from operating at least up to that third level — but only against opponents capable of that kind of thinking.
-
Against tough players, both sides may be:
-
Representing something,
-
Anticipating how the other interprets it,
-
And then countering that interpretation (and so on).
-
-
At very high levels, this “I know that he knows that I know…” loop can get so deep that you can’t confidently judge anymore — that’s when game theory becomes safer than trying to out-guess each other.
Against weak players, this multi-level thinking is often a waste because:
-
They don’t systematically think about what you have,
-
And they definitely don’t think about what you think they have.
A Key Calling Principle: When They’re Sure You’ll Call
One of the most important practical rules in the chapter:
If your opponent is sure you are going to call, he is almost never bluffing.
So:
-
If you’ve:
-
Shown strength,
-
Put in a lot of action,
-
Or clearly indicated you’re “stuck to the pot,”
-
-
And your opponent now bets or raises:
-
That bet is almost always for value, not a bluff.
-
You should fold mediocre hands that can only beat a bluff.
-
Examples:
-
You bet the river, they raise
-
Most players don’t bluff-raise there, especially when you’ve been betting all along.
-
A routine hand should often be folded.
-
-
You raise, they reraise on the end
-
Again, almost never a bluff from typical opponents.
-
Unless you can beat some real hands they’d reraise with, you should usually fold.
-
This logic underpins the idea of “stopping bluffs” from Chapter 20: if you’ve signaled that you are likely to call, and your opponent bets anyway, assume real strength.
The Corollary: When They Think You Might Fold
The flip side:
-
If your opponent believes there is a good chance you’ll fold, then:
-
A bet might very well be a bluff.
-
You should be more willing to call with marginal hands in those spots.
-
This underpins “inducing bluffs”:
-
You show apparent weakness → they think a bluff can work → their bluffing frequency goes up → you profit by calling more.
Betting Decisions Based on What They Think You Have
Psychology also affects when you should bluff or value-bet:
When They Think You Are Strong
-
Bluffing becomes more attractive:
-
They fear your strength and may fold a lot of hands.
-
-
Value betting with medium-strength hands becomes worse:
-
They’ll fold most worse hands and continue only with better ones.
-
Your value bet gets called by too many superior hands and not enough worse ones.
-
When They Think You Are Weak
-
Bluffing becomes dangerous:
-
They’ll want to “catch you” and call lighter.
-
-
Value betting becomes better:
-
They pay off your fair and good hands because they don’t believe you.
-
So the right action with the same holding can change purely based on your perceived image in that moment.
Using Psychology to Shape Future Image
Sklansky also covers deliberately creating impressions for future exploitation:
-
You might:
-
Check a strong hand (like trips) in one spot so that later, when you bet a similar-looking board, opponents don’t believe you have trips.
-
Or check a vulnerable open pair so they fear trips and check behind, accidentally giving you a free card.
-
Usually, you should choose the play with the best immediate expectation. But sometimes, especially in no-limit or long sessions, you might:
-
Make a slightly bad bluff on purpose and show it.
-
Or fold a strong hand and show it.
Why? To:
-
Plant a strong image in opponents’ minds (“He overbluffs” / “He makes big laydowns”).
-
Then exploit their future adjustments:
-
More calls from them → more value for your real hands.
-
Fewer bluffs against you → fewer tough calling decisions.
-
This works especially against players who:
-
Are good enough to “use” this new information,
-
But not so good that they realize you know they’re going to adjust and are planning around it.
When to Use Psychology — and When Not To
Sklansky finishes with some big-picture guidance:
-
Against good players:
-
You must think in terms of:
-
What they have,
-
What they think you have,
-
And what they think you think they have.
-
-
Psychology and deception are vital, and often profitable.
-
-
Against weak players:
-
Fancy multi-level thinking is usually wasted (and can be costly).
-
The best strategy is basic, straightforward value:
-
Bet good hands,
-
Fold bad ones,
-
Don’t overcomplicate.
-
-
-
Against very tough/expert players:
-
Multi-level psychology can spiral into guesswork.
-
Sometimes you must fall back on game theory-style play:
-
Balanced frequencies,
-
Less reliance on outguessing,
-
More on unexploitable strategy.
-
-
Core Takeaways
Chapter 23’s main lessons:
-
Poker psychology = thinking about what your opponents think, not just table talk.
-
You should habitually:
-
Read what they have,
-
Infer what they think you have,
-
And sometimes go one more level: what they think you think they have.
-
-
Use this to:
-
Decide when a bet is likely a bluff or value,
-
Choose between bluffing and value betting yourself,
-
Adjust for how strong or weak you appear in their eyes.
-
-
Occasionally make small, intentional “mistakes” to shape your image and harvest bigger profits later — but only against the right opponents.
Ultimately, this chapter ties psychology directly back to the Fundamental Theorem of Poker: the better you understand how your opponents think, the closer your decisions get to how you’d play if you could see their cards.
