I play micros for the time being , 2 tables is good for me cause with more I make big mistakes . Cash games nowadays I play rarelly , I prefer tournaments , satellites , sometimes sngs and spins .
I don't use HUDs , I use only my mind as you say , maybe in the future I 'll use one- I guess a HUD is essential nowadays . I tried in the past once but couldn't understant it lol
When i play cash games , almost always if I win one buy in I get away from the tables cause I am not good and I lose the winnings to bad beats or bad decisions , it has to be a very good run and me to be very focused , fresh (not tired) , passioned , not tilted , in order to continue playing to win more buy-ins
