More or less my experience. I’ll win a big one, stay too long, and end up giving some back. Or I’ll lose a big one and spend the rest of the night exploiting to get back to zero.
I have found that I tend to do better when I play a smart but extremely aggressive game. There’s always that risk of losing the big one when the 20% decides to nail you, sure. However, even at 1K/2K there are plenty of exploitable players to get you back to zero.
I would say 2K/4K is where it starts to change a bit; as you begin seeing sub-200 ranked players much more often. It’s right on the edge of comfort for my bankroll so I try not to play there too often, but it presents its own set of challenges which are different from medium stakes.
