Thinking in big blinds
Twenty thousand chips can be a monster or a corpse — only big blinds tell you which. Learn to count your stack in BB and read the zone it drops you into.
Chips lie, big blinds tell the truth
Blinds keep rising, so raw chips shrink in real terms every level. The only stable unit is the big blind. Divide your stack by the current BB: 24,000 at 400/800 = 30 BB.
Same chips, different worlds
Two players with 24,000 chips are in opposite spots: one at 200/400 (60 BB, cruising), one at 1,000/2,000 (12 BB, in danger). The BB count — not the pile — sets your strategy.
Blinds are 1,000/2,000. You have 20,000 chips in the cutoff, folded to you. Thinking in big blinds, what's the play?
Effective stack is what really matters
In any pot the depth is set by the shorter stack. Cover 80 BB but your only opponent has 18 BB? It's an 18 BB pot — neither of you can lose more.
Why short stacks flip to push-or-fold
Near 10–15 BB a normal open commits too much to fold to a re-raise, yet leaves too little to play postflop. Shoving fixes it — you win the blinds and antes uncontested and keep your fold equity (the chance everyone folds and you take the pot without a showdown).
Two players are all-in preflop. Which starting hand is the favorite?
Don't wait for zero
Bleeding from 20 BB to 5 BB waiting for aces kills your fold equity. A 15 BB shove scares people; a 4 BB shove gets called by anything. Take your shot while it still bites.
- Stack in BB = your chips ÷ the current big blind. Recount every time blinds rise or you play a big pot.
- Effective stack (the shorter stack in the hand) sets the real depth — not your own chip count.
- Rough zones: 40 BB+ full poker, 15–25 BB shove/re-shove, under 10 BB pure push-or-fold.
- Convert every opponent's stack to BB too — it shows who can pressure you and who you can pressure.
- Use your fold equity while it exists; don't blind down to 4 BB waiting for a premium.
Test yourself
Answer them all — 20/25 to pass. Every answer gets an explanation.
You have 30,000 chips and the blinds are 500/1,000. How many big blinds is that?
Stack in BB = chips ÷ big blind = 30,000 ÷ 1,000 = 30 BB.
Why is counting your stack in big blinds more useful than counting raw chips in a tournament?
Rising blinds mean a fixed chip pile shrinks in real terms; big blinds measure your true survival room.
You cover the table with 90 BB. You get into a pot with one opponent who has 14 BB. What is the effective stack?
The effective stack is the smaller of the two — neither player can lose more than 14 BB in the hand.
Two players both have 24,000 chips. Player A is at 200/400; Player B is at 1,000/2,000. Who is in more danger?
Same chips, different blinds: A has 60 BB (comfortable), B has 12 BB (danger zone).
Roughly what stack depth marks the pure push-or-fold zone?
Below roughly 10 BB there aren't enough chips to raise-fold or play postflop, so playable hands are jams.
At 60 BB or deeper, why can you play more speculative hands like small pairs and suited connectors?
Deep stacks reward implied-odds hands because there's enough behind to get paid when you connect.
What does 'effective stack' mean?
You can only win or lose up to the shorter stack, so that number defines how deep the pot plays.
A player with 5 BB shoves all-in into your 100 BB stack. How big is this decision for you?
The effective stack is 5 BB, so you're risking only 5 BB to call regardless of how deep you are.
Why does a short stack switch from open-raising to open-shoving around 10–15 BB?
At that depth a raise leaves you awkwardly committed, so an all-in captures fold equity and avoids tough postflop spots.
You have pocket sevens at 9 BB, folded to you in middle position. Best play?
At 9 BB a good pocket pair is a mandatory jam — folding it and blinding out is the real error.
How do antes affect short-stack shoving?
Extra chips in the middle increase the reward for winning the pot uncontested, so wider shoves become profitable.
An 80 BB stack plays a pot against an 18 BB stack. What is the effective stack depth?
Depth is always set by the shorter stack: neither player can win or lose more than 18 BB, so it plays as an 18 BB pot.
Why should you convert your opponents' stacks to big blinds, not just your own?
Knowing each opponent's BB count reveals who's desperate, who's looking to re-shove, and who can call you lightly.
A player left to act behind you has 13 BB. Why does that threaten your steal-raise?
Around 13 BB is the classic re-shove range, so an opener risks facing an all-in that's hard to call.
What is the danger of blinding down from 20 BB to 5 BB while waiting for a premium hand?
Fold equity shrinks as you get shorter; a 5 BB jam gets called wide, turning your shove into a coin flip.
You have 45 BB. Which description best fits your situation?
Around 40–60 BB you have room for normal raising and postflop play without shove-or-fold pressure.
When should you re-check your stack in big blinds?
Your BB depth changes as blinds rise and pots are won or lost, so recount often to stay in the right strategy zone.
You have 8,000 chips at 100/200 with a 200 ante posted by each of 9 players per orbit. Ignoring antes, what's your BB count?
8,000 ÷ 200 = 40 BB; antes make you effectively a touch shorter in survival terms but the raw BB count is 40.
At what approximate stack depth do open-shoves and re-shoves become a core part of your toolkit?
In the 15–25 BB short-stack zone, postflop play shrinks and shoving/re-shoving becomes standard.
Which statement about deep stacks (60 BB+) is correct?
Depth gives you flexibility for float plays, set-mining, and multi-street pots that short stacks can't play.
Fold equity is best described as:
Fold equity is the extra value your shove gains from opponents folding, and it's largest when your stack still scares them.
You have 100 BB but your only opponent in the hand has 6 BB. Should you look at deep-stack plays like floating and set-mining for implied odds?
The shorter 6 BB stack caps how much can go in, so all the deep-stack maneuvers are off the table.
You have A-10 offsuit with 12 BB in late position, folded to you. What's the standard play?
At 12 BB you can't profitably raise-fold, and A-10 is far too strong to fold from late position — so you jam.
Using this lesson's stack-depth zones, at what depth are you in pure push-or-fold?
The rough map puts 60 BB+ at full postflop play and under 10 BB at pure push-or-fold, with 10-15 BB as the danger zone just above it.
Why can a 50 BB+ big stack call your all-in more lightly than a short stack could?
A deep stack risks only a fraction of its chips, so it can gamble on marginal spots that would cripple a shorter player.

-
Roughly what stack depth marks the pure push-or-fold zone?
Answer Under about 10 BB
Below roughly 10 BB there aren't enough chips to raise-fold or play postflop, so playable hands are jams.
-
At 60 BB or deeper, why can you play more speculative hands like small pairs and suited connectors?
Answer You have room to maneuver postflop and can win a big pot when you hit
Deep stacks reward implied-odds hands because there's enough behind to get paid when you connect.
-
What does 'effective stack' mean?
Answer The smaller of the stacks of the players contesting the pot

A player with 5 BB shoves all-in into your 100 BB stack. How big is this decision for you?
Answer A 5 BB decision — you can only lose 5 BB by calling
The effective stack is 5 BB, so you're risking only 5 BB to call regardless of how deep you are.
-
Why does a short stack switch from open-raising to open-shoving around 10–15 BB?
Answer A normal raise commits too much to fold, but there's not enough behind to play postflop — so jamming is cleaner
At that depth a raise leaves you awkwardly committed, so an all-in captures fold equity and avoids tough postflop spots.

Why should you convert your opponents' stacks to big blinds, not just your own?
Answer It tells you who can pressure you with re-shoves and who you can pressure
Knowing each opponent's BB count reveals who's desperate, who's looking to re-shove, and who can call you lightly.
-
A player left to act behind you has 13 BB. Why does that threaten your steal-raise?
Answer They're in prime re-shove territory and can jam all-in over your open
Around 13 BB is the classic re-shove range, so an opener risks facing an all-in that's hard to call.
-
What is the danger of blinding down from 20 BB to 5 BB while waiting for a premium hand?
Answer You lose fold equity, so your eventual shove gets called and you're just flipping
Fold equity shrinks as you get shorter; a 5 BB jam gets called wide, turning your shove into a coin flip.
-
You have 45 BB. Which description best fits your situation?
Answer Comfortable — standard raise-or-fold poker with full postflop play available
Around 40–60 BB you have room for normal raising and postflop play without shove-or-fold pressure.
-
When should you re-check your stack in big blinds?
Answer Every time the blinds go up, antes start, or you play a meaningful pot
Your BB depth changes as blinds rise and pots are won or lost, so recount often to stay in the right strategy zone.
-
You have 8,000 chips at 100/200 with a 200 ante posted by each of 9 players per orbit. Ignoring antes, what's your BB count?
Answer 40 BB
8,000 ÷ 200 = 40 BB; antes make you effectively a touch shorter in survival terms but the raw BB count is 40.

At what approximate stack depth do open-shoves and re-shoves become a core part of your toolkit?
Answer Around 15–25 BB
In the 15–25 BB short-stack zone, postflop play shrinks and shoving/re-shoving becomes standard.
-

Answer You have the most room to maneuver postflop and can play a wider, more speculative range
Depth gives you flexibility for float plays, set-mining, and multi-street pots that short stacks can't play.
-
Fold equity is best described as:
Answer The chance that your all-in makes opponents fold, winning the pot uncontested
Fold equity is the extra value your shove gains from opponents folding, and it's largest when your stack still scares them.
-
You have 100 BB but your only opponent in the hand has 6 BB. Should you look at deep-stack plays like floating and set-mining for implied odds?
Answer No — the effective stack is 6 BB, so the hand plays as a short-stack pot
The shorter 6 BB stack caps how much can go in, so all the deep-stack maneuvers are off the table.
-
You have A-10 offsuit with 12 BB in late position, folded to you. What's the standard play?
Answer Open-shove all-in
At 12 BB you can't profitably raise-fold, and A-10 is far too strong to fold from late position — so you jam.
-
Using this lesson's stack-depth zones, at what depth are you in pure push-or-fold?
Answer Under 10 BB
The rough map puts 60 BB+ at full postflop play and under 10 BB at pure push-or-fold, with 10-15 BB as the danger zone just above it.
