I have both GTO+ and Pio and was comparing results for a hypothetical river spot where OOP jams 1 PSB with a balanced range and the two solvers give different call frequencies for their bluff catchers. I know that if OOP jams a balanced range, IP's bluff catchers are indifferent to calling or folding so in practice their call % shouldn't matter, but why do the two solvers give different answers?
Board: 9s 9h 9d 2h 3d
Pot 100
Rake set to 0 for both
OOP jams 100
OOP value range: JJ-AA (24 combos)
OOP bluff range: JTs, QJs, QTs (12 combos)
IP range: 22-88
GTO+ calls 1/2 of the time, which is what I would expect if IP is indiff, but Pio calls 1/3 of the time. Again I know it doesn't matter but I'm just trying to understand how the systems work.
