How to play Go, the game that humans keep losing to Google's highly intelligent computer brain

After seeing Google's artificial intelligence system "AlphaGo" beat one of the best Go players alive last week, I decided to try the popular game myself.

I know how to play the game, but I'm still a beginner. The last time I played Go was almost 15 years ago, so I didn't have any luck beating any of the online gaming systems I played against.

But playing Go a few times made me realize why Google may be so obsessed with it - and it probably has nothing to do with the game itself.

Here's how to play Go, and what I learned returning to the game after more than a decade.
