Bet sizing: telling a clear story with your chips

Every chip you push forward says something. A tiny bet says *"I want a call"*; a big bet says *"fold or pay dearly."* The leak isn't betting too big or too small — it's betting the same amount regardless of the situation, so your story never changes and good opponents read you for free.

Three questions set every size:

• Who folds and who calls to this number? Pick the size that gets value from worse or folds out better — whichever is your goal.
• What does the board do to ranges? Dry boards reward small bets; wet, dynamic boards reward big ones.
• What's the SPR? (stack-to-pot ratio). Low SPR means you're committing; high SPR means you have room to maneuver across streets.

If you can't say *why* this size and not another, you're guessing.

Open to a flat 2.2–2.5bb from every position at a full table — same size whether you have AA or A5s. Identical sizing protects your range; a bigger raise with premiums is a tell waiting to be exploited.

• Antes in play? Bump to 2.3–2.5bb because the dead money makes wider calls profitable, and you want to charge them.
• Limpers ahead? Raise to 2.5bb + 1bb per limper. One limper → ~3.5bb; two → ~4.5bb. Limping behind almost never beats raising or folding.
• Short stacks (under ~20bb)? Drop to a min-raise (2bb) or move to a push/fold framework — you have no postflop room to justify paying more.

The common open leak is inflating sizes to 3bb+ "to thin the field." At modern tables that just bloats pots out of position and torches your stack when you whiff.

Continuation betting is where most postflop chips leak. Stop firing a robotic half-pot into everything. Choose from three tools by board texture:

• Small (25–33% pot) on dry, static boards you connect with as the preflop raiser: K-7-2 rainbow, A-9-4, Q-J-3 two-tone-but-quiet. You bet your whole range cheaply, deny equity, and keep their floats in line. Heads-up, single-raised pot, this is the default.
• Big (66–80% pot) on dynamic, draw-heavy boards: 9-8-6 two-tone, J-T-7, T-9-5ss. Here you charge draws and build the pot with your strong hands. Polarize — bet big with value and your best semi-bluffs, check the in-between.
• Check with your medium hands and air on boards that smash the caller's range (low connected boards when you raised from early position). Betting just isolates you against everything that beats you.

Pots compound. If you bet 1/3 flop and 1/2 turn, the river bet — even at 2/3 pot — is already a big number of chips. Use that.

• Value on the river: size for the worse hand you're targeting, not for comfort. Against a likely top-pair call, 75–100% pot prints. Betting 40% "to get called" leaves half your value on the table.
• Overbet (110–150% pot) when your range is much stronger than theirs and the board lets you have the nuts they can't: a river that completes your obvious draws, or pairs the top card you'd have. Overbets generate folds *and* huge value because villains can't profitably bluff-catch.
• Bluffs must match value sizing. If you only overbet your bluffs and bet small with value, you're an open book. Pick the *line*, then put both value and bluffs into it at the same size.

Example: you raise A♠K♠, c-bet small on K-7-2, turn 5 you bet half, river 2 (board K-7-2-5-2). Bet ~80% pot — KQ, KJ, and pocket pairs pay you; checking wastes the hand.

Stack-to-pot ratio is the quiet boss of sizing. Compute it on the flop: remaining stack ÷ pot.

• SPR 1–2 (you 3-bet pre, or short): you're committing. Don't dribble — bet sizes that set up an all-in by the turn so you're never priced into a bad fold with top pair.
• SPR 3–5 (typical single-raised pot): you have one comfortable street of maneuvering. Two two-thirds-pot bets get it in by the river; plan both before you fire the flop.
• SPR 6+ (deep, or many limpers in): slow down. Big multi-street aggression with one pair is how deep stacks lose huge pots. Use smaller bets, keep the pot controllable, and don't stack off light.

Work backwards: decide which street you want to be all-in on with your value, then choose flop and turn sizes that arrive there naturally.

Quick diagnostic — if any of these sound like you, here's the patch:

• "I always bet half pot." → Split into a small-bet bucket (dry boards) and a big-bet bucket (wet boards). One size for all textures is a leak by definition.
• "I open 3bb with aces, 2.2bb with the rest." → Flatten to one open size. Mixed sizing telegraphs your strength.
• "I bet small on the river to get called." → If they'd call 80% with the hands you beat, you torched value. Size up; let them make the mistake.
• "My bluffs are smaller than my value bets." → Mirror your sizes across both. The story has to be identical or thinking players exploit it.
• "I min-bet to 'see where I'm at.'" → That bet folds out nothing and pays off everything. Either bet a meaningful size or check.

Golden rule: pick the hand you're trying to beat or fold, then choose the smallest size that accomplishes it — and use that same size for the bluffs that share the line.
