If you want to improve, you might ask someone stronger to play a teaching game with you, or find someone who is willing to play with you and discuss the game.
 

1. For that you may add a post with subject "request for a teaching game" in the forum to look for opponents, or ask there for other resources or places where to get one.
    
   
2. You can set up a game offer in the waiting room, so that other players can join it. Post a game with "request teaching game" as comment. Restricting the level of the teacher would probably be a good idea. To accomplish that, use the option "Require Rated Opponent" and choose a rating range.
    
   
3. The Go Teacher is an account that specialises in teaching go. Teachers provide comments during play and the game may be reviewed when finished. If you wish to start a game with The Go Teacher, please read the information about settings carefully.
