If you play well post-flop and you have a decent understanding of how your opponents will respond to your desires, that is, all you need is 100% hands from the button, if no one has opened a pot before you. You can practice: select the day on which you will open 100% of the hands with the button. Thus, you will greatly advance in understanding the strength of the position. Obviously, such a strategy rarely gives you a reliable positive result, but you can quickly learn the main lesson.It is also worth looking at the blinds, if there are weak players who often fold, then a similar 100% range can ultimately bring you a lot of money in the long run. If you study your earnings in 6-max poker, then almost always you will see especially large numbers when playing with a cutoff and button. I already said why, position is 2/3 of your success!
