I read a couple of poker books and I thought I could win, which was not the case.
Fortunately for me I have a decent chess level, 1930 in rapid, and I simply changed poker books for chess books and returned to the club. I have not lost a lot, but I realized if I don't win money why play something I enjoy less than my favourite game since I was a child.
As the game is helping me not to gamble, I wonder if it is documented from a medical point of view similar cases where chess helped.
