I find I tend to do better when I'm not so intensely focused on the game. When I focus on the game, I'm always looking for ways to angle or apply pressure or
bluff, every pot I see go to someone, I think, that could have been mine!
When I pay less attention, I can stick to my game rules, which work, and I make the money. I usually scroll reddit, when I only have one table up. If I have 3 tables, going, there is enough distraction between jumping table to table, so I can not worry about anything else.
2 tables is tough.. I still look at reddit, but not as intensely.
So what do I do to focus? Try not to focus.
