A lot of stuff is out there but a lot of it will not be suitable for your opponents.
Try to get some money from
freerolls and buy something that's not too expensive so if it doesn't work out for you then its not a big deal.
Hopefully the source is suitable for the games that you are currently playing and explains situations and why you do something and what to look out for.
You have to look for info that you can use.
Not something from a high stakes grinder or someone playing hundreds of SNGs an hour or something that you're not doing.

I would recommend Super System 2 not 1 by Brunson because its for people just starting out and it gives solid fundamental advice on all the games.
If you study that, not read it but study it and think about
hands then I would say you would be light years ahead of all the " " ones doing all the crazy aggressive donk bets, bluffs, preflop stupid raises that make no sense, checking when they should be betting, etc.
Just 100% stupid stuff that beginners and people you will find in microstakes and freerolls. All ins with 100BBs preflop lol in a tourn.
I mean, pretty sure the guy says "you don't
bluff a bad player" in that book, lol.
That alone would make some of these ppl better players, lol. If they actually used the advice, lol.
LOL I'm playing in a omaha freeroll on ACR killing time and I'm watching ppl bet 4x preflop with holdem hands! lol Like jj68 or some nonsense lol or a big pair with 2 bad kicker cards like aa73 and they don't know why those are mediocre hands (especially multi way) at best but SS2 explains it, clear as day.
Book is like 15 years old and is solid.
You just have to know how to apply it.
