I play on KGS as yoyoma, usually 1d.

I enjoy reviewing games, both my own and to help others.

Quick links:

Some links



  • [ext] http://gobase.org/studying/joseki/basic - Learn some basic joseki, there is a lot of other good information on this site.
  • KGSTeachingLadder - Receive free teaching, with the understanding that you will teach those weaker than you. (Rooms -> Room List -> lessons -> KGS Teaching Ladder)
  • GTL - Look at amateur game reviews and get your own games reviewed.
  • DonTAttachWhenAttacking - Important concept, I wish this page was a little better, maybe sometime I'll put some work into it.
  • KikashiAndInfluence - This page is ok, but scroll to the bottom and read Charles Matthews "point of kikashi against weak/strong groups".

Math and Statistics


Can I live under that 4-4 stone? What about this enclosure? What about this one? What about this other one? Answer to all these: It depends on the surroundings. Walls halfway across the board make a difference!

Endgame and Counting

Interesting positions from my own games

Maybe I could put these on various BQMs or Random Tseumego and use an index here to keep track of them for my own use.

My go rating history

Gaps represent times I didn't play that much, except the 1996 gap I was playing sporadically, but I don't have records of my IGS games (I got these few data points I have from GTL games). It's too bad KGS wasn't around to preserve my history from 28k to 5k!

1995-04 - 28k IGS
1995-08 - 24k IGS
1995-09 - 23k IGS
1997-03 -  5k IGS
2002-10 - 10k KGS
2002-11 -  8k KGS
2002-12 -  7k KGS
2003-06 -  5k KGS
2003-08 -  4k KGS
2003-12 -  3k KGS
2004-03 -  2k KGS
2004-05 -  1k KGS
2004-09 -            * rating algorithm change, later bottom out around 5k
2006-09 -            * rating algorithm changes again for KGS3, later recover to around 1k
2006-11 -  1k KGS
2006-12 -  1d KGS
2007-09 -  2d KGS
2007-11 -  1d KGS    * After here I couldn't get back to 2d for a long time
2009-09 -  2d KGS    * Finally returned after 2 years!
