I did not think that an effective stack is the minimum count of chips that I can lose. I thought that an effective stack is the minimum count of chips that I can win against an opponent. As a rule, I often have a short stack and therefore an effective stack is equal to my stack. But, changing my mindset, I improved my game.
I did not analyze my own range, I always thought that it was very tight, but after reading the recommendations I thought that the proposed range is so wide that I decided to analyze my range, and I was surprised that I have only two ranges for UTG / Utg + 1 / MP/ LO / HJ, as the HJ range from guidelines, and for CO / BTN / SB, as the BTN range. I found that my early position range is so loose, and that is what leads to eliminate from MTT. I will try discipline in the future.
Thanks for this course, Katie and Collin.
