Many Go players suggest starting with Atari Go (aka Capture Go). It has the same rules as Go, but the starting position is predetermined and the winner is the player to capture the first stone. You only need to play a few rounds of Atari Go, say 30 minutes to an hour to get a grasp of the capturing rules and then you can move to a 9x9 or 13x13. I'd go straight for the 13x13 because it's not that much bigger but it ha…

The drawback with Capture Go is that it emphasises the capturing part perhaps a bit too much. I prefer introducing players to a variant with the same rules as capture go, except the winning condition is "having the most pieces on the board". This is essentially the same thing as regular go, but without all the fuffing about with learning scoring and such. When played on a small enough board, the games take about as l…

What do you mean by sophistication in this context?

In chess there are various pieces with differing powers, with Go it seems like they all have similar powers. Again, I don't really know the game and might be wrong, but that was my impression.

Actually, that's the draw of Go over Chess for me. The different powers in chess seems arbitrary. We can easily imagine aliens coming up with Go by convergent evolution, but not Chess. Too many free parameters.

Yes, the fascination lies in the strategies that emerge from the simple base.

A historic moment here, folks. Incredible, and in my opinion a little terrifying.

Not that terrifying? It's a very special purpose-built tool. We'll still always have Calvinball! https://xkcd.com/1002/

I went looking for that xkcd to post an "obligatory xkcd needs updating" comment, but you beat me to it!

What surprises me about it is that connect four was only solved in 1995; that seems relatively late for a 6x7 grid with only 7 possible moves per turn.

Actually, putting a piece of software in front that infers board states from a video feed would be an easy problem.

That's actually true - going from the pixel level to the board state is trivial and not particularly interesting.

It's trivial today. It would have been interesting perhaps twenty years ago?

I definitely agree. Just a few games (ie. just a few minutes) of Atari Go every now and then should be enough to teach that and then move on the the real thing.

Your game variant sounds interesting, btw!

One thing that's cool about Go is that the pieces get their value and power not from the rules, but from how they are used. In an actual game of Go, you will find groups of ten pieces that are casually thrown away, and you will find single pieces that the whole game revolve around. In the rulebook, they are the same piece, but in actual effort expended to save/attack them, you'll see they're valued vastly differently.

This happens in chess too, of course, but in Go their value is decided only based on how they are used. The sophistication is about the same, but the rules are simpler.

...it was the last stand of homo sapiens in the man vs machine... But who made that machine? I'd say a more precise evaluation would be that the ability to program a machine to assist in playing chess outdid the ability to play chess without such assistance.

Your point is entirely valid, but was already made by the very comment you are replying too..

Indeed... Apologies to parent.
