Go Pattern Matching

I'm not sure I would say it's mostly about pattern matching. It's a little bit more like there are strategic considerations that I think take a long time to build. And then there are tactical considerations, which on a small scale, you can sort of develop a stable of them where you just kind of understand they're related. How long have you been playing go for? Probably 15 years or so. Do you still play a lot now? I don't play a much now. But I really enjoy teaching people.
