Wow, it's really nice that you want to help people for free with their poker skills. I get it that you might be really into this stuff and thus helping out people, but I wonder if there is a bigger game for you here. Sure, it's sweet that people are willing to help for free, but humans are rational beings, so in any situation they are usually looking for some gain (even if it's not direct and purely economic). What's your game here? Why are you helping people for free? Is it because then you can start providing services for money or something else? Don't get me wrong, it's just that 'too good to be true' offers are making me suspicious. It's often safer if you know what kind of profit the offerer is going for.
There's no catch, I'm doing hand reviews, simply because I like doing them, but it's also to build up a CV that I can use in the future to possibly ''benifit from economic gain'' hope that answers your question. You can find tons of free information online already, the likes of, charlie carell, lex veldhuis, gripsed poker. I'm just offering hand reviews to beginning - advanced players who feel uncertain about their plays in alot of spots.
The thing what I really don't understand is this : Why are you even asking this? All free services can eventually possibly benifit the maker. It seems to me that you're trying discredit my integrity for some reason, which I really can't respect.
I'm offering a good, free service. To the people who want to make use of this opportunity, go for it. If you don't want to make use of this, just keep on scrolling and don't bother replying.
