Pot geometry & overbets

Pot geometry answers a planning question: if a polarized range wants to put the effective stack in over the remaining streets, what equal fraction of the pot gets there? It is a baseline—not proof that betting is good. Large bets need enough value combinations at the top, suitable bluffs, and an opponent range that cannot punish the size by continuing only with better hands.

  1. Set the destination.Decide whether your value region truly wants stacks in by the river.
  2. Count streets and SPR.Fewer betting rounds or a deeper stack requires a larger fraction.
  3. Test the top end.Confirm a nut advantage and whether the opponent is capped.
  4. Build both poles.Name value that welcomes calls and bluffs that benefit from folds.

Worked example: two-street geometry

The turn pot is 20bb with 80bb behind. Betting the same fraction on turn and river requires about 100% pot each time: bet 20.0bb, creating a 60.0bb river pot, then shove the remaining 60.0bb. That arithmetic fits a polarized range on a static runout. It does not mean one pair should automatically play for 80bb. If your value region becomes uncomfortable when called on the turn, use a smaller size or check; the range is not polar enough for the destination.
