The most exciting thing about go at the 10-kyu level is the understanding you are starting to grasp, but which seems just out of reach. Some of the fundamentals come quickly, be it basic life and death, “kiddie” joseki, or just the flow of the fuseki and middle-game.
One of the things common to most of us at this level is that one or more of these basics are weak in favor of a stronger ability. One of the tasks necessary to reach single digit kyu is to identify these weaknesses and strengthen them accordingly. I’ve played some games against slightly stronger rated players (1-3 stones) and led almost the whole game, sometimes by as much as 25 or so stones, only to lose in the end because I allowed them to live when I could have killed (or lost a sizeable group myself). As a result, I’m focusing my study for the next few months on life and death and tesuji.
Something that’s also necessary, now that we’re really starting to get an understanding of the path of go, is to not be discouraged at how far away upper level play seems. This path we tread is by no means easy, but such discouragement is the major pitfall.
