I've spent some time playing with SNGWiz, trying to understand how it work and I think I may have found a bug :
The BB and the SB are calling push with 21+ and 16+ respectively.
If I push with the button SNG Wizard say I have 74.8 % fold equity but when I do the math I find 66.36 % :
P(BB and SB folding) = 1 - ( (P(BBCallPush) + P(SBCallPush)) - P(BBCallPush and SBCallPush) )
SNGWizz say BB has the same calling range for on and two push calling, I'm fine with that. So :
P(BB and SB folding) = 1 - ( (0.21 + 0.16) - P(0.21*0.16) )
P(BB and SB folding) = 1 - (0.37 - 0.0336) = 1 - 0.3364 = 66.36%
Also, I'm wondering about the way SNG Wizard calculate the calling range when a player limp in EP-MP and call a push from LP.
