Adjust the pot, stack and number of streets. Compare three scenarios with their bet sizing, MDF per street and final calling range.

Modify pot, Cash stack and streets number. The results are updated automatically.

Geometric size

size = 0.5 * (((pot + 2 * stack) / pot)^(1 / n) - 1)

Where pot is the current pot, stack is the effective stack and n is the amount of streets.

MDF of each street

MDF = 1 / (1 + size)

range end of call

Rango final = MDF ^ n

If there is a single street, the final range of call matches the MDF of that single decision.
