As I stated, this is an eye-opening conversation for me. I have only been an active poker player for about three years, and my personal experience has been that the people I play with are adamant about this issue. It's a matter of personal integrity that you don't announce that you are playing blind unless you are actually playing blind. At no time have I ever gotten the impression that these people think it's okay, even outside of our own private game. To me, lying about playing blind falls well outside of the many other factors that are implicit in playing poker, where deception is the norm.
Up until today, I would have never suspected that another PCF member who I might be playing poker with at either a local home game, or at a PCF meetup, would engage in this activity. If you tell me at a PCF meetup that you are playing blind, I would have trusted that you were being honest about this particular issue. So apparently, now I know better... Sorry, but it's rather a sad moment for me.
I pulled this from an online site. Seems like a reasonable definition: Angle Shooting usually refers to using underhanded or unethical tactics in an attempt to gain an edge against opponents.
To me, announcing to the table that you are playing blind, when in fact you are not, falls very clearly within the definition of an underhanded tactic to gain an advantage over your opponent. It is very different from being dishonest about the cards you hold when asked by an opponent, who obviously has no right to know what you have prior to showdown.
And my reasoning for mentioning those other acts which are clearly cheating is to make the point that I personally would question the integrity of anyone who would lie about announcing that they were playing blind. If they would do that, then I would also be suspicious that they might be capable of engaging in other forms of angle shooting, or downright cheating.
