Still a beginner, and I haven't played a lot yet, so I have no idea of my strength. Perhaps you should ask Kosh.....
Kosh: Arjen, you're reasonable strong. Keep up the good work!
Thanks Kosh, for your encouragement and getting me started on Go in the first place!
I'm a student in mathematics from the Netherlands, currently in my third year. I try to divide my time between my study and my (many) other interests, such as Go, music, reading, sports, learning Chinese and drawing. I play the guitar (though not really well. It's supposed to be jazz-I really love Sonny Rollins, Miles Davis, Tal Farlow, Wes Montgomery, John Coltrane, Cannonball and Dexter Gordon).
