Nothing personal whatsoever about this, GURU but if you check my, or many others, info under their avatar you will see exactly where they are from. In my case you can check my profile and find my email address. Point being, when you post a challenge here, in the dark, as you have done it has to be taken with a grain of salt. IE, talk's cheap. I believe what they are interested in is, who are you? Where are you? Who is your guy? What game? Will you honestly travel to play? How much woud you like to bet?
Again, GURU, this is nothing personal, just what is usually expected if you actually intend to make a challenge. Openness and honesty.
