Anyone can get access to the same information if they want to. These programmes just make the process easier. I'd hardly describe that as cheating
I haven't used PT yet I still can't get the bloody thing to work so I'm no expert.
Someone told me yesterday that they are making a little program, I don't want to say too much about it but I understand you can analyse how your opponents play using PT I guess by spending a lot of time going through their stats and HHs and stuff. This guy is making software that will do the analysis as you are playing and make a prediction of what cards they have depending on how they are playing the hand. He is only using info that everyone can access...
I think it's pretty well known now that people have adapted SNG PT to give real time ICM calcs while they play SNGs. They are only using info that everyone...
Someone else I know who has only just started playing poker told me the other day how cool their bot is. It's making them 2 BB/100 or something at the micro limits.
I think things like PT may have started off as a cool little program to help you analyse your stats but people are expanding and tweaking it to be much more than that. Unfortunantely it's too late to do much about it now. I just hope I can make that big score before internet poker changes beyond all recogniton.
