Man, that's awesome. Chess is a lot of fun but I don't know if I could handle the 3 minute or 1 minute games. I can barely play a game of chess in 30 minutes never mind 1 LOL. That's great though, chess and things like that are excellent for our brains and our thinking. I'm glad that you enjoy it and do it as a hobby, hobbies come in all shapes and sizes so it's important you have them!
