I think he's trying to offer free poker course for free and if it's truly, then anybody that is interested can easily jump on it and grab the opportunity if op is not trying to deceive us here. That will be appreciated for those who will go for it but I think there is a motives behind this because it looks like he is trying to bring something in apart from the poker course.
In this time where you have the internet ready to assist you do anything you want, it is just with a seconds to get to follow some poker players on video and with that the possibility of scamming is out rather than the lesson op is offering that doesn't look like free in all aspects. What an interested person need to do is to type in poker game on YouTube and all you are there. Learning poker is simple like you learn the cards, example the single card, pairs of same number, double pairs of two separate identical numbers, triple pairs etc.
I don’t see anything wrong with OP’s offer as long as he’s being honest but if you are a smart person, exploring the internet alone is a wise move as you can gained all the free details available online and also there are a lot of free video tutorials in youtube where they can be very helpful particularly for newbies in poker games. In the end, your experiences in poker games will always give the you the best lessons to learn.
