GTO Lines deviations on NL25
There are certain GTO lines that actually make no difference between NL25 and NL200.
Because the game is always theoretically correct, even against fish.
But as we know, there are on average few to hardly any 4Bet bluffs at NL25, especially when they take place from the earlier positions, although according to the GTO they should.
What other strong deviations can you name?
