In my opinion, to become a professional poker player is very difficult and great thing, while the failure is very general to poker players, but not any poker players dare to face their failure, I believe that the final winners in poker is the ones who can learn the lessons from their failure, and thereby they continue to improve and their poker skill, in the end, they successfully do what they hope to do.
From personal experience, to professional poker players, marked cards are not strange, they should have saw many times that poker players used marked cards, maybe at beginning, they don’t recognize marked cards, but they have strong observation, few things can escape from their eyes, on the other hand, they must know the marked cards must use with infrared contact lenses, marked cards sunglasses or other devices, so there are many professional poker players use those high-tech poker players to protect themselves.
