I have applied this type of psychology always with option 1 and I play without stress. If I lose, I assume my loss, and if I win, it's like lifting a trophy. Do you think it's a way to escape from that little pressure that is exerted when playing? Have you ever applied this type of psychology?
Playing with the money that we can afford to lose will certainly put a little pressure if we face bad results. I think, as long as you can maintain your habits, by just playing with spare money, you can control your emotions because the pressure you will get will be at a normal level. It will be different when we play beyond our limits which can give us greater pressure that, for sure, will be difficult to control.
