The Fundamentals of Bet Sizing

Every bet should have a purpose. Either you're betting for value (wanting a call from worse hands) or as a bluff (wanting better hands to fold). Your sizing should reflect that purpose.

Common Bet Sizes

Size% of PotWhen to Use
Small25-33%Dry boards, thin value, cheap bluffs
Medium50-66%Standard c-bets, balanced ranges
Large75-100%Wet boards, strong value, polarized
Overbet100%+Nutted hands, strong bluffs, polarized

Board Texture Matters

Dry boards (like K-7-2 rainbow) favor smaller bets because ranges don't connect well. Wet boards (like J-T-9 with flush draw) favor larger bets to charge draws and protect value hands.

Key Insight

Your bet sizing should be the same with your value hands and bluffs at the same frequency. This makes you harder to exploit.

Value Betting

When value betting, think about the maximum size your opponent will call with worse hands. Sometimes small bets get called by more hands, extracting more value overall.

Bluffing

Bluffs need to be large enough to make your opponent fold, but not so large that you're risking too much. A good bluff gives your opponent bad pot odds to call with their draws.

Common Mistakes

  • Always betting the same size: Predictable and exploitable
  • Betting too small with strong hands: Leaves money on the table
  • Overbetting with medium hands: Only gets called by better
