What is your current level of ability and current stakes that you are playing?
GTO is a total misnomer in my opinion. It suggests that applying Game Theory is the Optimal method of playing, but in reality it couldn't be further from the truth. If you are playing against the perfect GTO player and you play perfect GTO, then both players would break even (variance aside), but no one can actually play GTO perfectly because we are humans, not super computers.
At micro and low stakes GTO offers the least value because no one can play anything close to GTO. Instead, you should be focusing on developing a sound fundamental strategy and learn to exploit player pool tendencies and specific play leaks that you may have picked up on.
So, I have played probably a 1000 GTO hands on GTO trainer apps over the last 2 days and that was my introduction to GTO.
Two things I have noticed is that the apps don't explain why they recommend certain actions. They recommend a small or large bet, but not a medium bet. Why? I can only guess and if my guess is wrong then it is probably harmful. I guess that small bets almost ensure value but value is small, also small bets induce raises and make betting the next street easier. Large bets increase fold
equity, increase pot size to get more value, and is probably good when you want to inflate pot size or get a fold, like when you have the nut flush draw.
Second thing I have noticed is that GTO seems to be almost no pressure strategy. Aggression or pressure seems to be one of the key characteristics of winning play. You induce folds, preventing V from realizing equity. You make stronger hands fold, you make people scared to bet in case they get raised, allowing you to realise more equity. You build bigger pots which allows you to get max value when you have premium hands, you play bigger pots which makes most players uncomfortable and they overfold- players generally don't want to get it all in with one pair.
GTO so far seems to be take almost no risks, although I do note there was commonly a 20% all in option when SPR was 1.5:1 or less and I had nothing. I am not sure if that would work at low stakes....they will call with weak flushes any straight, sets, good 2 pair. Higher stakes I think they could fold more. I was surprised that it didn't like me betting a straight when board paired or flush was possible.
I also found that it seems some apps actually use data from real player pools, any trainer that uses data from real player pools would be a highly effective trainer and I think if I had the ability to try different styles against such a program it would be very effective. It would be great to know if 4-betting in 5% is profitable, and I want to know if going all in pre with AK is profitable in ZOOM. I think maybe not.
I wanted it to tell me how to play TT on QQ6 board. It kind of
tells me, but the answer is check fold? or check call fold. MAybe that is the right answer. Maybe I have not learned what it was actually telling me. I tended to notice the main recommended action, and sometimes not notice that 15% of the time it should be a raise.
