You've almost gotten it right. In fact, 9x9 go is used to teach people the rules of the game, and to help get them acquainted with fighting, since it's basically a big fight from start to finish with too small of a board to think about much else. 13x13 is used to get those same students accustomed to thinking about the rest of the board, and 19x19 is the real game. 9x9 and 13x13 are cute, and it's quite impressive that UCT-based programs are getting very good at playing at the smaller size, but it's unrelated, in an important way, to the larger size board. they're different games entirely. I think that I've played 15 games on a 9x9 board, and several hundred on a 19x19 board. I have no idea what it would mean to be "the world's best 9x9 player", because nobody keeps track of these things and I can't easily go get a book about 9x9 theory. It's an unimportant game from the point of view of the typical 19x19 player, but it is a separate and distinct game -- if you study and play 19x19 go for most of your life, you will no longer be spending much time playing the 9x9 version, and probably won't be all that interested in 'mastering' it. similarly, if you play 9x9 go for too long, it will take you far too long to understand why everything is so much harder on a 19x19 board. So yes, humans become weaker at a game that they don't study, write books about, spend thousands of years trying to master, etc. It doesn't mean that 9x9 is harder *as a game*, it just means that it holds no real interest *as a serious game*. To belabor this even further, if you were to take everyone playing 19x19 go right now and convince them that no such thing ever existed and that only 9x9 go exists, in a short amount of time they would all be very much stronger 9x9 players (relative to the game itself), because 9x9 is a less deep game. something like "the best" opening move might be found, for instance, whereas nobody knows this same fact on a 19x19 board. s. ____________________________________________________________________________________ Never miss an email again!
