All the details should be available for you to see so I only want to add that the key to this tournament is that it will be handicap games. Handicap games seem to be quite uncommon in our modern times. I find that odd since it’s present throughout the history of Go. So, please enjoy this tournament and maybe experience a new way of playing.\n\nThis is a casual tournament to encourage more regular play for my students but there is also a prize for the winner. The winner of the tournament will receive a free two-hour lesson.\n\nI hope to have more tournaments like this in the future. Let’s see how it goes!\n\nGood luck to all!",
