Let's assume that we open BU and BB or SB calls with certain ranges.

And the board comes Ks 9d 5c for example.

According to [APPS. of poker], BU should have the same betting frequency regardless of opponent's range.

But, if I set IP's range and compare two results of vs.SB and vs.BB's ranges in PIOSOLVER, our IP betting frequency is severely different.

Does anyone know why?
