I looked through your site so far, and I didn't see any math or any hands, which was discouraging. It's good to think about cognitive biases and how to reduce them, but really the way to make money at poker (especially at SNGs and especially at small/microstakes) is to understand starting hand ranges, position, tournament strategy, and postflop play as deeply as possible, and then learn how to apply those concepts to hands. You can't do that by thinking about theory, you need to actually look at specifics.
To be brutally honest, it's hard to see how you're going to differentiate your product from the hordes of poker blogs and forums that are already out there but have the advantage of having great poker players contributing.
Try looking at the book Small Stakes Holdem by Ed Miller. It's a good example of taking fundamental insights about how poker players play badly and using them to create an actionable strategy that says "play this hand, raise in this situation."
Thanks for the clarification. I understand your goals better now. That said, let me suggest that there's a tension between some of what you're saying. On the one hand, you want to focus on the links between rationality/bias-overcoming and poker. That's a great plan, and it seems like you could make a great contribution there. (I'm envisioning a less-mystical Tommy Angelo here.)
But on the other hand, you seem to also be focusing on poker instruction, which I think might be a problem. Are you planning on deriving and teaching a strategy for poker based on first principles? I think that's impractical, because the game is just too complicated. However, it seems like any other approach would dilute your brand and distract your from making a truly novel contribution.
I think you would be well advised to ditch the idea of teaching players who are complete novices and focus more on helping players who are at an intermediate+ level now develop a rational approach to the game.
Best of luck with the project!
