Tournaments: the final exam
Every tournament decision collapses into two numbers you check before your cards. Master that reflex and most hands play themselves.
Two numbers, then your cards
Ask two things first: effective stack in big blinds, and what stage am I in? Those pick your entire toolkit before you ever look at your hand.
Chips are not dollars
The chips you win are worth less than the chips you lose: you can only win first once, and busting costs everything. That is ICM, and it turns cash-game auto-calls into clear folds near a pay jump.
Final exam. You have 11bb in the big blind. It folds to the button, who open-shoves for 9bb. You look down at this. Call or fold?
Fold equity is your engine
As you get shorter you win most chips without a showdown. A jam wins two ways: fold-out now, or called with live equity. Waiting for aces at 10bb is how you blind out.
Read the payout curve
Flat payouts (satellites are the extreme) mean survival is everything — chips past the threshold are worthless. Top-heavy MTTs pay the winner big, so accumulating for the win earns its risk.
Final table, 4 left, hand-for-hand ICM pressure. A big stack shoves and you cover only one player. You hold 88 for 12bb. Call or fold?
SNG vs MTT: same math, faster clock
A single-table SNG is a compressed MTT: fast blinds, a quick bubble, ICM biting almost from the start. Master the SNG push-or-fold endgame and you've mastered the MTT endgame — it's identical.
- Know two numbers before your cards: effective stack in bb and your stage — they select your whole strategy.
- Chips aren't dollars: ICM makes lost chips cost more than won chips, so marginal all-ins near pay jumps become folds.
- Fold equity is your engine as you shorten — attack first, don't wait for aces at 10bb.
- Big stack hammers the medium stacks near bubbles and pay jumps; they can least afford to bust.
- Read the payout curve: flat/satellite = survive, top-heavy = accumulate and play for the win.
Test yourself
Answer them all — 20/24 to pass. Every answer gets an explanation.
What are the two numbers you should identify before looking at your hole cards in a tournament?
Effective stack depth selects your strategy toolkit and stage tells you how much ICM has bent the chip math.
What does 'effective stack' mean in a heads-up pot?
You can only win or lose up to the smaller stack, so that number governs the pot's stakes.
Why are the chips you win worth less than the chips you lose in a tournament?
Prize-pool equity is non-linear: doubling your stack does not double your dollar equity, which is the core of ICM.
At roughly what effective stack does open-jamming (push-or-fold) become your primary weapon?
Around 10-12bb and below, min-raising leaves you pot-committed, so shoving to maximize fold equity is standard.
On the money bubble, who should the big stack most relentlessly pressure?
Medium stacks fold to preserve tournament life, so they are the most exploitable targets for a covering big stack.
In a satellite tournament where the top N finishers all win identical seats, what matters most?
Flat payouts mean once you're safely in, extra chips add no equity — you just need to not bust.
What is 'fold equity'?
Fold equity is the portion of your all-in's profitability that comes from opponents folding rather than from showdown.
Why does correct aggression increase as your stack gets shorter?
Combining fold equity with showdown equity makes proactive shoving more profitable than passively waiting to blind out.
Four players remain at a final table; you're 2nd in chips with 20bb and the covering chip leader jams. You hold pocket nines and two shorter stacks are still in. Why can folding be correct?
ICM says risking your tournament life against a bigger stack when others are closer to busting can cost more equity than the flip is worth.
How does a single-table Sit & Go differ in tempo from a large MTT?
With a tiny field and steep relative pay jumps, SNG endgame math is dominated by ICM very early.
In a standard top-heavy MTT payout, why is it worth taking calculated risks to build a big stack?
When the prize curve is steep at the top, accumulating chips to play for the win has outsized dollar value.
What effect do antes have on your strategy compared to a level with no antes?
Antes inflate the pot, improving the risk-reward of stealing and shifting ranges wider.
A short stack with 8bb open-jams into you and you cover them on the bubble. Compared to a covering big stack jamming, how should you treat this?
Committed short stacks jam wide and can't be pressured, so calling requires real equity rather than exploiting fold equity.
Which situation makes a marginal all-in that would be automatic in a cash game into a clear fold?
ICM pressure near a pay jump makes survival more valuable than the small chip-EV edge of the marginal call.
During the rebuy/add-on period of a rebuy tournament, how does the chip math compare to the freezeout stage?
When re-entry is available, the downside of busting shrinks, so profitable chip-EV spots can be taken more freely.
You have 45bb early in a large MTT at a passive table. What general approach fits this spot?
At 40bb+ you have room for standard deep-stacked raise, continuation, and postflop play.
The final self-check asks whether a mistake in the current spot is 'reversible or fatal.' What does that distinguish?
Reversible mistakes cost recoverable chips; fatal ones bust you and forfeit all remaining prize-pool equity.
Two decisions have identical hole cards but opposite correct plays. What most often explains that in tournaments?
Because chip value depends on stage and payout shape, the same hand can be a call in one context and a fold in another.
As the covering chip leader four-handed at a final table, why can you profitably open a very wide range?
ICM pressure falls on the players you cover, letting you steal relentlessly with hands you couldn't otherwise play.
What is the danger of 'waiting for aces' at a 10bb stack?
At 10bb, blinds and antes erode your stack quickly, so you must act with a wide shoving range rather than wait.
Which factor determines whether accumulating chips past a certain point adds meaningful dollar equity?
Flat payouts (satellites) make surplus chips worthless, while top-heavy MTTs reward stacking up for the win.
It's folded to you on the button with 14bb on the bubble, holding AKo, and the big blind covers you. What is the standard play?
AKo is far too strong to fold, and bubble ICM pressure on the big blind gives your jam huge fold equity.
Roughly what effective stack range calls for 'raise-or-fold' poker while avoiding bloated pots without a plan?
At shallow depth you lack room to maneuver postflop, so entering pots with a clear raise-or-fold plan avoids trouble.
Why are Nash push-or-fold charts especially reliable in the late stages of a 9-max SNG?
When everyone is short and pots are contested pre-flop as jam-or-fold, equilibrium shove/call ranges apply cleanly.
Review — all 24 questions & answers tap to expand
-
What are the two numbers you should identify before looking at your hole cards in a tournament?
Answer Effective stack in big blinds and your tournament stage
Effective stack depth selects your strategy toolkit and stage tells you how much ICM has bent the chip math.
-
What does 'effective stack' mean in a heads-up pot?
Answer The smaller of the two stacks involved
You can only win or lose up to the smaller stack, so that number governs the pot's stakes.
-
Why are the chips you win worth less than the chips you lose in a tournament?
Answer Because you can only win first place once, but busting costs you everything (ICM)
Prize-pool equity is non-linear: doubling your stack does not double your dollar equity, which is the core of ICM.
-
At roughly what effective stack does open-jamming (push-or-fold) become your primary weapon?
Answer Under about 12-15 big blinds
Around 10-12bb and below, min-raising leaves you pot-committed, so shoving to maximize fold equity is standard.
-
On the money bubble, who should the big stack most relentlessly pressure?
Answer The medium stacks, who have the most to lose from busting before the pay jump
Medium stacks fold to preserve tournament life, so they are the most exploitable targets for a covering big stack.
-
In a satellite tournament where the top N finishers all win identical seats, what matters most?
Answer Survival — accumulating chips past the qualifying threshold is nearly worthless
Flat payouts mean once you're safely in, extra chips add no equity — you just need to not bust.
-
What is 'fold equity'?
Answer The chance you win the pot immediately because opponents fold to your aggression
Fold equity is the portion of your all-in's profitability that comes from opponents folding rather than from showdown.
-
Why does correct aggression increase as your stack gets shorter?
Answer A shove wins two ways — everyone folds, or you get called and still hold equity
Combining fold equity with showdown equity makes proactive shoving more profitable than passively waiting to blind out.
-
Four players remain at a final table; you're 2nd in chips with 20bb and the covering chip leader jams. You hold pocket nines and two shorter stacks are still in. Why can folding be correct?
Answer If you call and lose you bust in 4th, while two shorter stacks were likely to bust before you
ICM says risking your tournament life against a bigger stack when others are closer to busting can cost more equity than the flip is worth.
-
How does a single-table Sit & Go differ in tempo from a large MTT?
Answer Blinds rise fast, the bubble arrives quickly, and ICM dominates almost from the start
With a tiny field and steep relative pay jumps, SNG endgame math is dominated by ICM very early.
-
In a standard top-heavy MTT payout, why is it worth taking calculated risks to build a big stack?
Answer First place pays many times the min-cash, so contending for the win is where the real money is
When the prize curve is steep at the top, accumulating chips to play for the win has outsized dollar value.
-
What effect do antes have on your strategy compared to a level with no antes?
Answer They increase the pot before cards are dealt, rewarding more aggression to win the larger dead money
Antes inflate the pot, improving the risk-reward of stealing and shifting ranges wider.
-
A short stack with 8bb open-jams into you and you cover them on the bubble. Compared to a covering big stack jamming, how should you treat this?
Answer Short stacks are often committed and call/jam wider, so you need a stronger hand to call than to attack a medium stack
Committed short stacks jam wide and can't be pressured, so calling requires real equity rather than exploiting fold equity.
-
Which situation makes a marginal all-in that would be automatic in a cash game into a clear fold?
Answer Being close to a significant pay jump where busting costs a locked-in payout
ICM pressure near a pay jump makes survival more valuable than the small chip-EV edge of the marginal call.
-
During the rebuy/add-on period of a rebuy tournament, how does the chip math compare to the freezeout stage?
Answer Busting is less costly because you can buy back in, so chip-EV gambles are more acceptable
When re-entry is available, the downside of busting shrinks, so profitable chip-EV spots can be taken more freely.
-
You have 45bb early in a large MTT at a passive table. What general approach fits this spot?
Answer Play a full postflop game — you're deep enough to see flops and outplay opponents
At 40bb+ you have room for standard deep-stacked raise, continuation, and postflop play.
-
The final self-check asks whether a mistake in the current spot is 'reversible or fatal.' What does that distinguish?
Answer Losing chips you can recover versus busting out near a pay jump, which ends your equity
Reversible mistakes cost recoverable chips; fatal ones bust you and forfeit all remaining prize-pool equity.
-
Two decisions have identical hole cards but opposite correct plays. What most often explains that in tournaments?
Answer The payout structure and ICM pressure differ between the two spots
Because chip value depends on stage and payout shape, the same hand can be a call in one context and a fold in another.
-
As the covering chip leader four-handed at a final table, why can you profitably open a very wide range?
Answer Opponents risk busting before a pay jump if they clash with you, so they fold too often
ICM pressure falls on the players you cover, letting you steal relentlessly with hands you couldn't otherwise play.
-
What is the danger of 'waiting for aces' at a 10bb stack?
Answer You blind out — passivity at short stacks bleeds chips faster than premiums arrive
At 10bb, blinds and antes erode your stack quickly, so you must act with a wide shoving range rather than wait.
-
Which factor determines whether accumulating chips past a certain point adds meaningful dollar equity?
Answer The shape of the payout curve — flat curves cap the value of extra chips, top-heavy curves reward them
Flat payouts (satellites) make surplus chips worthless, while top-heavy MTTs reward stacking up for the win.
-
It's folded to you on the button with 14bb on the bubble, holding AKo, and the big blind covers you. What is the standard play?
Answer Open-shove all-in — premium hand plus big fold equity against a big blind that can't call light
AKo is far too strong to fold, and bubble ICM pressure on the big blind gives your jam huge fold equity.
-
Roughly what effective stack range calls for 'raise-or-fold' poker while avoiding bloated pots without a plan?
Answer About 15-25 big blinds
At shallow depth you lack room to maneuver postflop, so entering pots with a clear raise-or-fold plan avoids trouble.
-
Why are Nash push-or-fold charts especially reliable in the late stages of a 9-max SNG?
Answer Short stacks and a tiny field make jam-or-fold the dominant, near-solved decision type
When everyone is short and pots are contested pre-flop as jam-or-fold, equilibrium shove/call ranges apply cleanly.
