100BB Stack Strategy: The Balanced Deep Game
Last Updated: April 2026
Why 100BB is the Standard
In cash game poker, 100 big blinds is considered the "standard" stack depth. This is where the game becomes most complex, with enough room to play postflop but not so deep that everything becomes a coinflip.
In this guide, we'll explore the key concepts for playing effectively at 100BB.
The Middle Ground
What Makes 100BB Special
At 100BB, you have enough room to:
- Play complex postflop strategies
- Float, raise, and use mixed strategies
- Extract value from strong hands while denying equity
But you're also not so deep that:
- Every hand is a preflop all-in situation
- Implied odds become astronomical
- Postflop play becomes impossibly complex
The Commitment Question
At 100BB, the key question is: "Am I willing to get all-in on this street?"
If the answer is yes, you can bet more freely. If no, you need to use smaller sizing or consider checking.
Playing the Flop at 100BB
Continuation Betting
At 100BB, continuation betting remains a core part of your strategy. But you should be more thoughtful about it than at shallower depths.
When to c-bet:
- You have a strong hand and want to build a pot
- The board favors your range (dry, high cards)
- You have a specific goal (deny equity, get value)
When to check:
- The board is dangerous (coordinated, favors opponent's calling range)
- You have a marginal hand
- You're trying to induce bluffs
Sizing Considerations
Standard c-bet sizing is typically 50-66% of the pot
At 100BB, this sizing:
- Gives you a reasonable chance to fold out draws
- Builds a pot without going overboard
- Keeps you manageable if called
Smaller sizing (25-33%) works when:
- You're betting to deny equity with a medium-strength hand
- The board is somewhat coordinated
- You want to keep opponent's range wide
Larger sizing (75-100%+) is for:
- River value bets with the nuts
- Turn and river bluffs in polarized spots
- When you want to fold out strong hands cheaply
Turn Strategy at 100BB
The Turn Changes Things
The turn card often significantly changes the situation. At 100BB, you need to reassess:
1. Did the turn help or hurt your hand?
- Did you improve? (trips, two pair, straight draws completing)
- Did the board become more dangerous?
2. Did it change the range dynamics?
- Does your opponent's calling range strengthen?
- Are there new draws to worry about?
3. What's your new goal?
- Are you trying to get value?
- Are you trying to deny equity?
- Should you give up?
When to Second Barrel
The second barrel (betting both flop and turn) should be deliberate. Consider betting if:
- You have a strong hand that wants value
- The turn card favors your range
- Your opponent showed weakness on the flop
Consider checking if:
- The turn completed obvious draws
- Your opponent showed unusual strength
- Your hand is medium strength and vulnerable
Playing Made Hands Deep
Top Pair
Top pair is often the starting point for most decisions at 100BB.
On dry boards (good for you):
- Bet for value
- Your hand is relatively stable
- You can often get called by worse hands
On wet boards (caution required):
- Your hand is more vulnerable
- Consider checking and calling rather than leading
- Be prepared for difficult turn decisions
Middle Pair
Middle pair is where 100BB strategy gets tricky.
Generally play conservatively:
- Check more often than you'd like
- Don't over-invest if you face resistance
- Look for spots to get cheap showdowns
Overpairs
Overpairs are strong but tricky:
- They fear many turns (Aces, Kings)
- They can be vulnerable on coordinated boards
- Balance between betting for value and protecting
Playing Draws at 100BB
The Beauty of Deep Play
At 100BB, draws become more playable because:
- You have room to call bets and see cheap cards
- Implied odds are reasonable
- You can sometimes raise to take the pot away
When to Raise Draws
Raise draws when:
- You have strong draws (open-ended, flush draws)
- The board is good for your range (you have the advantage)
- You can represent strong hands
Call with draws when:
- You're getting good odds
- The pot isn't too large
- You have backup equity
When to Give Up Draws
Fold draws when:
- You're facing large bets with poor odds
- The board is very dangerous
- You have weak backdoor draws
Defense and Check-Raising
The Check-Raise as a Weapon
At 100BB, the check-raise is essential because:
- It lets you play pot control while keeping initiative
- You can often get all-in by the river
- It balances your checking range
When to Check-Raise
Good spots:
- With strong hands on boards favoring your range
- Against frequent c-bettors
- When you have backdoor draws as backup
Bad spots:
- Against tight opponents who only c-bet with strong hands
- On very dry boards where you have no backup if called
The River: Maximizing Value
At 100BB, the river is where you often make your biggest profits (or mistakes).
Value Betting
When you have the nuts or near-nuts:
- Bet large (pot or overbet)
- You want to get called by the thinnest value hands
- Don't be cute - extract maximum value
Thin Value
Sometimes you have just a "thin" value hand - like middle pair on a board where opponent can't have much.
When to bet thin:
- Opponent's range is capped
- They showed weakness throughout
- The board doesn't favor their range
When to check:
- The board is scary and your hand isn't strong relative to their range
- You're likely behind if called
Bluffs
River bluffs at 100BB require:
- A board that favors your range
- Opponent who folds reasonably often
- A reasonable story (you've shown strength)
Don't bluff as a "default" - it should be a considered decision based on the specific spot.
Common Mistakes at 100BB
Mistake 1: C-Betting Too Frequently on Wet Boards
If you always c-bet T-9-8 with two spades, observant opponents will raise you with their strongest hands and crush you.
Mistake 2: Not Balancing Check-Raising Ranges
If you only check-raise with the nuts, you're too easy to play against. Mix in some medium-strength hands.
Mistake 3: Overvaluing Middle Pair
At 100BB, middle pair is often just a "get to showdown cheaply" hand, not a value-betting hand.
Mistake 4: Poor Turn Planning
Don't c-bet the flop without a plan for the turn. Think ahead: "If called, what will I do on different turn cards?"
Key Takeaways
- 100BB is the sweet spot - complex enough to be interesting, not so complex that it's impossible
- Be thoughtful about c-bets - the flop sets the tone for the entire hand
- Plans matter - think about the turn before you bet the flop
- Balance your ranges - mix checking, betting, and raising with various hand strengths
- Maximize the river - this is where you often make the most money with strong hands
