Fold EQ calculator

MDF = P / (P + B).

B = F(B+P)+(1−F)(CallEQ × (2B + P))
F = [B−CallEQ×(2B+P)] / [(B+P)−CallEQ×(2B+P)]
Value Region = (1 − MDF) to (1 − MDF / 2)

Nodelock Fold EQ Calculator

Fix villain call frequency C; solve break-even equities.

−B + (P+2B)·C·EQc + (1−C)·(P+B) = 0
EQc = [C(B+P) − P] / [C(2B+P)]
ThinEQ = 1 − C + EQc

ThinValue BetSize Calculator (Consider R)

Same thin-value solve, but opponent raise frequency f makes the bet 0EV.

W(1 + 2B) − (W + L)B − f(W + L)B = 0
B = W / [(W + L)(1 + f) − 2W]
%

Finding Winning/Losing combos

Enter BetSize and either L or W to get the breakeven other side.

R = B / (1 + 2B)
W = R·L / (1 − R)
L = W·(1 − R) / R

Thin value Size Calculator2

Enter your hand equity to get the thin-value bet size (pot = 1).

MDF = 1 / (1 + B)
EQ = 1 − MDF / 2
MDF = 2(1 − EQ) · B = 1 / MDF − 1

Value Bluff ratio Calculator

Enter any two of Value / Bluff / BetSize to solve the third.

B / (1 + 2B) = Bluff / (Value + Bluff)
R = B / (1 + 2B) = Bluff / (Value + Bluff)
