First of all don't be greedy, there is a very old saying that my mother always said, (from grain to grain, the chicken fills the chat)
Second be patient, wait for the right moment.
Third, don't be vindictive when someone takes part in your chips.
Fourth, observe your opponents
I probably need to spend more time on theory, I think I don’t have enough of this, and also playing at the required limit. I very often play at an inflated limit, that is, not according to the bankroll!!!
