Pot Geometry refers to planning post-flop multi-street betting so that the river reaches a target pot size. Betting similar proportions on each street can geometrically increase the pot, making it easier for strong hands to extract value or apply pressure as a bluff.
Pot geometry plans multi-street bet sizing so that the river can shove the effective stack (e.g., 33%–75%–150% three-street structure). Low SPR compresses into two-street commitment; high SPR requires a larger flop α. In Pot-Limit games, the pot-limit-bet rule must be used to verify the maximum bet, differing from No-Limit's all-in mindset. Use the calculator on this page to instantly compute the break-even equity, then cross-check the numbers against opponent ranges, position, and turn/river plans — avoid just memorizing formulas without applying them at the table.
Flop bet too large leaves no bluff sizing on river; flop bet too small creates an awkward SPR. Ignoring opponent's effective-stack cap. Geometry inconsistent with range narrative, making river polar bets not credible. Also, don't treat Solver frequencies as gospel without checking pot odds; when information is incomplete, ICM and SPR remain the first principles in tournaments.
After preflop action, sketch a three-street geometry plan before betting. Practice simultaneously with SPR and bet-sizing. Review hands with the question "Can I cleanly shove on the river?" and adjust flop/turn sizing. Each week, pick five real hand histories and recalculate with the same tool, then revisit terminology to internalize concepts like pot odds, ICM, and SPR that auto-link.
Scenario：Context: Tool example scenario: pot-geometry
Flop pot 30, effective 100, target river pot ≈ 90.
Must grow approximately 3x on the turn and river. 2. Context: Tool example step: pot-geometry
Turn 75% pot → River 75% pot approximately achieved 3. Context: Tool example step: pot-geometry
Specifically, iterative calculation is required.
Conclusion：Geometric betting allows the pot to grow smoothly, avoiding SPR imbalance.
Scenario：Flop pot 10BB, effective 70BB. The nuts wants to get full pot value.
Target river pot about 50–60 BB 2. Reverse Flop/Turn Bet Sizing Ratio 3. Avoid an oversized flop that leaves no room for the river.
Conclusion：Using geometric betting to plan street betting is more stable than making impulsive decisions on each street.
