Just searched for a subject on Go, I have played chess for about 20 years now. Played Go for about 2 on and off. Go is a much harder game than chess, easy to learn almost impossible to master. Being a computer scientist I first came across Go when I was introduced to it by a tutor at uni, I understand certain things about Go like we cannot as of yet program a computer to beat a human player(unlike chess, reversi, draughts). Infact do you know that there are more scenarios in the game of Go than there are atoms in the universe - true if some what unbelievable.
For playing turn based I play on OGS and for real time play I play on KGS. I have to admit that I'm pretty dreadful at the game. Any way good to see people(well you) do know about it as its mostly popular in asian countries.
I have played chess since 2000. In my limited experience I have seen extensive analysis of games without examining attack and defense either simultaneously or separate, in addition to tactics vs. strategy both short term and long term. Conventional chess study reviews games but due to the constricted nature of the game it is highly difficult to say what will happen due to the none static nature of the game. I propose that those interested also study Go, or wei-chi. Below I have listed informative links so that those players here reading this forum may benefit from this schooling if they choose to do so:
The reason Im posting about Go in a chess forum is I like both games, but they are different and interact mentally in different ways. I started playing chess in 2000, didnt get serious about Go until about last year.
Go study I believe is profitable and this is why I study it also in terms of real world application. In Asia Go is used to train businesspeople and military and has been for about 2500 years. The rules are essentially unchanged since that time. It is from this game that the term "Atari" is from, which means to put in "check". http://en.wikipedia.org/wiki/Go_(game)
Here are some sites that will probably keep you occupied(im not kidding) for a long time, my favorites.
http://senseis.xmp.net/?PagesForBeginners, helps explain the game a huge library of free resource for study.
http://tsumego.tasuki.org/?page=tsumego free printable .pdf files(use these later once you understand the basics) some problems from as early as 1100 AD china. I printed some of these out and study them on my lunchhour at work.
http://www.u-go.net/classic/ classical files in .sgf (smart go format) sort of like a java game player on chess.com, but for Go, files can be viewed in http://www.godrago.net/ Drago is a .sgf file reviewer, freeware, I use it for reviewing Guan Zi Pu(above on the classical Go files).
For games, correspondence, like here at chess.com, I recommend www.dragongoserver.net , wide player base, free, site based in Sweden, in English. Im zazen5 there too. There is alsowww.wuzheng.me which is a newer site based in Hong Kong, also largely in chinese but with an english version now, again free correspondence.
For live Go I use the yahoo.ca games site, and the KGS Go server, here: http://www.gokgs.com/applet.jsp
For reviewing problems using java applet, www.goproblems.com is an interactive intuitive site in english that is free too.
There are plenty of .pdf files on Go floating around too on the net.
I hope you find Go as fun and as profitable as I do.
