In chapter 12 of The Course, Ed Miller introduces Skill #8—Exploiting Aggression—shifting your focus to beating 5-10 opponents who still play too many hands pre-flop but try to “dispose” of the extra junk by bluffing instead of folding.
Why This Skill Matters at 5-10
Miller frames 5-10 as a tougher, often “top of the room” game, where many players are looser and more aggressive than at 2-5. The big upgrade you need is learning to respond correctly when opponents apply pressure with bluffs—sometimes small stabs, sometimes stack-sized threats.
The big picture: once you can handle (and punish) over-aggression, you can beat almost anyone who insists on entering too many pots pre-flop.
The Core Principle: Range Strength Decides Whether You Fight
Miller’s central idea is simple:
-
If an opponent is betting from a strong underlying range, you generally get out of the way—even though they may have a few bluffs mixed in.
-
If an opponent is betting from a weak underlying range, you can call more, and sometimes raise, because their bluffing frequency isn’t supported by how many real hands they can credibly have.
So you’re not “trying to catch bluffs” in the abstract. You’re judging whether their overall set of possible hands is strong enough to justify the aggression.
Bloated Betting Frequencies: “Of Course He Bet” Is a Red Flag
A major tell of over-aggression at 5-10 is betting too often in predictable spots—especially when the bettor’s pre-flop range is wide and the caller’s range is tighter/stronger.
Miller argues that many players mechanically fire continuation bets (and other “auto-bets”) even when logic says they should slow down because they’re betting weakness into strength. When you recognize that mismatch, the adjustment is:
-
Don’t fold automatically to these routine bets.
-
Continue with a mix of hands—including some weak ones—because your range advantage protects you (your weak continues are “hidden” among your strong continues).
Whether you answer with calls or raises depends on factors like board texture, how likely they are to keep firing, and whether you can gain more information by letting them act again.
The Give-Up Line: Let Them Hang Themselves, Then Take It
Miller describes a common aggressive style: fire one or two barrels to win cheaply, then quit if you don’t fold.
Against these players, the plan is often:
-
call the flop (and sometimes the turn),
-
expect a lot of river check/give-up,
-
then bet the river when they surrender.
He also notes a practical twist: some aggressive players are “two-barrel” machines, but when they do bomb the river big, it can skew much more toward real hands—so sometimes the correct counter is to go back to “big river bet = respect it” logic, based on that player’s patterns.
The Last-Ditch Bluff: Aggression That Doesn’t Fit The Hand’s Story
Another pattern is the “late hero move”: a player takes a line that creates weakness (like checking back a key street), then suddenly springs a big bluff-raise at the end.
At low stakes you might fold because big bluff-raises are rare. At 5-10, Miller says you must at least consider calling more often, because the player pool contains more opponents willing to attempt these end-of-hand pressure plays—especially when their earlier actions don’t support a strong range.
This is where two ideas can clash:
-
“Don’t pay off players who don’t bluff enough.”
-
“Don’t overfold when the bettor’s range is too weak to justify the aggression.”
Solving that conflict is a judgment call based on that opponent’s bluffing tendencies and the logic of their line.
The Bully: High-Pressure Players You Can’t “Read”
Miller describes a particularly stressful opponent type: someone who doesn’t seem to care about money, plays tons of hands, and is willing to blast big bets to the river with both value and air.
Key points:
-
They feel intimidating because many players revert to passive, fear-based strategy.
-
They’re still constrained by math and range logic—so they’re beatable and often very profitable if you respond correctly.
-
However, fully countering them requires stronger range/texture understanding than the chapter can cover; Miller points readers toward deeper study for building a complete plan.
Practical Takeaways
-
Don’t hunt bluffs blindly. First ask: is their overall range strong or weak in this spot?
-
Identify auto-bettors whose frequencies are too high for their range strength—then stop folding so much.
-
Learn the common 5-10 aggression scripts:
-
bet-bet-give up
-
weak line → sudden river raise
-
bully pressure across streets
-
-
Your edge comes from refusing to overfold when their aggression isn’t supported—while still respecting spots where their range is legitimately strong.
