Frequently asked questions
Can a beginner take this course?+
Yes -- if they're willing to put up with a steep learning curve. The course's difficulty was balanced for intermediate players and amateurs with background in poker strategy, and is designed to help advance their game to professional levels. But the introductory chapters of the course are designed to catch up less experienced players.
What formats does the course teach?+
The principles taught in the course apply to all no-limit hold'em formats, but the hand examples are all from cash games. Cash game grinders will therefore get the most out of it -- there's no tournament-specific advice in the course.
Do I need a solver to follow along?+
No. All solver outputs are embedded directly in the course. A solver is helpful for going deeper but is not required.
How long do I have access?+
For life, after a one-time payment.
What is your refund policy?+
Due to the digital nature of this product and immediate access to all course materials, we generally do not offer refunds. Please review all course details and ask any questions before purchase to ensure it's the right fit.
