If it were possible to tell a solver (PIO,etc..) that there are no blinds and no antes at all...
What would it recommend?
As I think that a solver tries not to be exploitable, I understand that it would recommend... 100% fold. The best way, in that case, to avoid being exploitable at all.
Which would make it clear that the solver plays "another game". And that is why its results, more than helping are counterproductive for the 99,9% of players... (because there are some players using this tool in the right way, for right purposes, in certain study cases, but maybe just around 0,1% players or less...)
