            "description": "Dear players,\n\nAfter almost two years spent on this excellent Go platform, I found myself very confused. I had the impression that in time my knowledge of go has improved. That was not only an impression. I started as 13 kyu, but for a long time I was playing on the plateau of 12 kyu. Even better, for a few months I reached the level of 11 kyu, and occasionally even 10 kyu. But over the last two months I was a “victim” of a black series of losses, losing even to players that I have beaten at the beginning of my “career” and slipping down to an inevitable 14 kyu. I do not know exactly why, but I suspect that one of the reasons was playing in tournaments with players with a way too high a rank.\n\nThat is why I am proposing you a nice, relaxed and friendly tournament where everyone is almost equal in rank (13 to 15 kyu) and everyone has a chance to win and it is not a pre-destined victim.\n\nPlease come on board, for this experiment, which will allow us to continue improving our Go skills and also learning more about ourselves.\n\nThank you in advance.\n\nPS: This is the first tournament I create, so I do apologize for any possible errors and misfits.\n\nPetru",
