Does the Wizard provide advice while you are playing a hand?

No, the Wizard does not provide real time advice. Besides the obvious ethical reasons, providing real time advice is against the terms and conditions of most poker sites.

If anybody could play near perfect end game strategy just by following a software program’s advice, then everybody would buy the program. That would be good for the program’s author, but the games would soon become unbeatable.

It doesn’t take a lot of effort to learn end game strategy, but it takes more effort than most players are willing to put in. That is why it works. You make money off the players who do not put in the effort to improve.
