"pure fold"

I saw DNEGS post a hand from his h/u battle w/ Polk that stated he checked back AxJc on AJxxx cccc board and the solver said it was a "pure check"

What software allows you to be able to determine this? I'm assuming NOT Equilab...

I could be wrong on this, as I am not at the level of DNegs or Polk, but I believe the solver they use is called Piosolver to determine gto plays.

Yep, PioSolver.
