- First, and very importantly, OGS is a turn based / correspondence server. This means that the expectation is of making anywhere between one move every few days to a few moves a day -- games almost never get completed in one sitting. If you wish to play Go in real time, then your best bet is to try out KGS or IGS.
What we are trying to do with OGS is to create a site with a heavy focus on organised tournament and competitive play, with a fully integrated coaching and game reviewing system coming in the next few months to help players improve their ability. We also have some features that are unique to our Go server such as "conditional moves" (the ability to set up pre-programmed responses to your opponent's moves, thus speeding up the flow of the game).
