The only time Theory/GTO won't work.
1) The game is literally crazy. 100bb opens, normal opens are like 10x. Pots 6 and 7 way.
2) You think bluffing is some Allegory Myth. Bluffing is part of the game.
3) Volume. If you can't log enough hours to cycle range you will lose.
"Range Advantage" is not only a postflop strategy.
"Range Advantage" is an entire game plan.
Your opponents will be playing 50% of hands.
If you play 33% you simply crush them on all avenues.
The moment you start raising only 15% of hands and limping bad ones.
You are playing the exact strategy fish play and you will lose at it.
Been studying a number of players and ai bots.
I'm seeing the same strategies and hand combinations I came up with myself from understanding the game trees.
Back in the day in Madden I would find a play that works Everytime.
Local I would just crush everyone because they never seen the play or strategy before.
Then I would I go travel to a tournament out of state.
All the best players would show up.
At the end of the tournament everyone left in the final four would be running the same play that I found.
Great minds think alike. Always remember that when ever you second guess your play or scared to pull the trigger.
Learn to trust yourself as a strategist.
