In chapter 14 of Secrets of Professional Tournament Poker, Jonathan Little explains that when you have between 12 and 15 big blinds, tournament poker becomes almost entirely a pre-flop math problem. Complex post-flop maneuvering disappears, and most decisions revolve around whether to shove, call a shove, or fold. He emphasizes that most players make large errors at this depth by either waiting too long and blinding out or by committing chips without proper equity.
Antes significantly increase the value of shoving because the dead money makes even marginal pushes profitable. Near the bubble or in the money, he advises widening pushing ranges and tightening calling ranges due to tournament survival considerations.
General Philosophy: Push More Than You Think
Little argues that many players are too tight at this stack depth. Blinds and antes erode fold equity quickly, so passing up small positive opportunities often leads to worse situations later.
Key principles:
-
When folded to in late position, shove aggressively.
-
As your stack shrinks, widen your pushing range.
-
From early position, remain tighter unless extremely short.
-
Fold equity is your most valuable asset—protect it.
He stresses that accumulating even one big blind in expectation is meaningful when your stack is only 6–10BBs.
Position-Based Pushing Guidelines
Early Position
-
15BB: Raise premium hands small (around 2.25BB) and be prepared to continue. The range is tight because many players remain to act.
-
10BB: Eliminate small raises with marginal hands. Open-shove the hands you are willing to play to avoid difficult decisions versus re-shoves.
-
6BB: Push much wider due to the urgency of survival and the danger of blinding out.
Early position requires discipline because opponents’ ranges tend to be stronger.
Middle Position
As position improves, so does your fold equity.
-
15BB: Shove most playable hands except top-tier hands, which can sometimes be raised small for value.
-
10BB: Push a wide range.
-
6BB: Push very aggressively, as fold equity still exists and your stack is too fragile to wait.
He emphasizes the pattern: shorter stack + better position = wider shoving range.
Late Position (Cutoff & Button)
Late position provides maximum leverage.
-
Cutoff (10BB): Push a broad but slightly tighter range than the button because one extra player remains.
-
Button (10BB): Shove extremely wide—often close to any two cards—if blinds are not calling excessively.
-
6BB (Button or Small Blind): Push nearly everything except the very weakest hands.
The presence of antes makes these shoves highly profitable in expectation, even with weak holdings.
Small Blind vs Big Blind
This becomes largely mathematical:
-
If the big blind calls relatively tight, pushing any two cards is profitable.
-
Even if the big blind calls moderately wide, shoving most hands remains profitable due to dead money.
-
Only tighten up against opponents who call extremely wide.
The small blind is often one of the most profitable spots to shove.
Adjusting for Limpers
When someone limps in front:
-
If the limper folds frequently to shoves, attack aggressively.
-
If the limper limp-calls with strong hands, tighten drastically.
-
Against multiple limpers, medium-strength hands gain value due to dead money.
-
With very short stacks and multiple limpers, shoving can still be profitable even with minimal fold equity if enough chips are in the pot.
Fold equity remains the central variable—identify whether it exists before committing.
When Facing a Raise
When someone raises before you act:
-
At ~10BB, you often have little fold equity.
-
Your shove must rely on showdown equity.
-
Against tight openers, your calling range must be strong.
-
Against wide late-position raisers, you can shove much wider.
He illustrates that required equity depends on pot odds. If you need around 40–45% equity to profit, your hand must meet that threshold against the raiser’s range. The tighter the raiser, the stronger your hand must be.
Calling Shoves
Calling requires more discipline than pushing.
Key Steps:
-
Estimate the opponent’s shoving range.
-
Calculate the equity required based on pot odds.
-
Adjust for players left to act.
-
Tighten slightly when tournament life is at risk.
For example:
-
Versus a wide button shove, you can call with many pairs, broadway hands, and decent suited holdings.
-
Versus a tight early-position shove, your calling range narrows significantly.
Little highlights that misjudging ranges is one of the biggest leaks at this depth.
When Someone Shoves Over Your Raise
If you raise and face a shove:
-
Antes often give you strong pot odds (sometimes requiring only ~33% equity).
-
Against loose reshove ranges, many hands become mandatory calls.
-
Against tight reshoves, your calling range shrinks dramatically.
The key mistake to avoid is folding when you are priced in with sufficient equity. If the math dictates a profitable call, you must take it.
Isolating vs Calling
When a short stack shoves and you cover:
-
Very short stack (≈5BB): Usually re-raise to isolate.
-
Medium shove (≈10BB):
-
Call with weak hands (to preserve flexibility).
-
Re-raise with medium-strength hands.
-
Mix calls with monsters to stay balanced.
-
The goal is to maximize equity realization while preventing players behind from entering cheaply.
Half-Stack Raises
As a situational tactic, Little discusses raising to about half your stack instead of shoving, particularly against weak players who interpret it as extreme strength. This can occasionally generate extra fold equity, but it should be used sparingly and avoided against strong opponents.
The Stop-and-Go
Little is skeptical of the stop-and-go (calling pre-flop, shoving any flop).
He argues:
-
It often fails against competent players.
-
Open-shoving pre-flop is usually superior.
-
It works primarily against overly tight players who fold too often on flops.
He advises recognizing when opponents use it and adjusting by calling wider against aggressive players.
Core Lessons for 12–15BB Play
-
Poker becomes a numbers game—embrace the math.
-
Push wider than instinct suggests, especially in late position.
-
Tighten calling ranges compared to pushing ranges.
-
Adjust constantly based on opponent tendencies.
-
Protect fold equity and avoid drifting into 6BB territory unnecessarily.
-
Make decisions simple and mathematically sound.
At this stack depth, small edges compound quickly. Mastery comes not from creativity, but from disciplined range estimation and correct equity-based decisions.
