Yup, I moved the poker table to the bottom of the screen and balanced a cloakroom ticket over my cards. My gf at one point tried to tidy the ticket away

It is a good exercise, though, because if you're prone to passiveness, loose calls, lack of positional awareness and an unwillingness to read your opponents' playing styles, you can benefit from playing without the distraction of the cards. As I said in my blog, I ran utterly cold throughout the exercise; and yet I played 34/34 and won something like 80% of the hands I entered.
