This spectacular event happens on Saturday 15th (afternoon only) and Sunday 16th (all day) of September - that's the weekend after next - at Attenborough Nature Reserve, in Attenborough, near Nottingham. Please come along if you have even the slightest kind of interest in othello (aka reversi), because it's a fun weekend for everyone! People are welcome to stay at my place in Beeston on Saturday night if they want.
If you're coming by train, Attenborough station is a few minutes' walk away, if you know the secret way to walk there - don't follow the road, despite what Google maps might tell you; turn left out of the station, follow the road as it curves to the right, and then keep going in a straight line, carrying on when the road turns into a footpath, until you bump into the Nature Centre with accompanying conference room.
Check the timetables before you come, because trains only stop at Attenborough once an hour, probably even less than that on Sundays.
