BW-Go (Black & White Go) is a flexible, easy-to-use SGF editor to record, analyze, study and replay Go games. A Gnu Go computer player is available as a separate download to play against Android.

Also, download the free BW-DGS plugin to play on the turn-based Dragon Go Server.

If you encounter any problems, please mail me. Any feedback is welcome, including suggestions for later versions!

Features:
- All tools in one screen, including comments

- Unique 'tether' stone and markup placement: play a stone and move your finger away to check and correct the position.
Fast for tablets, accurate enough for a 25x25 game on a 320x480 screen!

- Correction for involuntary movements while lifting your finger

- Use the BW-DGS plugin (separate download) to make your moves on the turn-based Dragon Go Server! Check it out on SlideMe for details.

- Use a bot player (separate download) as an opponent or analysis helper. The bot is activated as just another tool, to be used in any SGF!
