The game I played with kendrew on 22 June 2015 at 16:15Z is incorrectly counted. The left bottom corner is impasse, which means that 3 white stones that separate 2 chains of black with an eye individually is alive. Finally i won the game, but i hope the counting program can be much good

Black can play A3 (close his eye) then capture all three whites. White can prevent this by playing B1. Unfortunately, the scoring algorithm misses white's move and considers black's move first. If you explicitly played B1, the server would have detected the seki situation.

It's better to play out tricky situations as far as possible to prevent mistakes by the server.

Moreover, if you played B1, A1+B1 wouldn't have counted as black territory either, and the eyes A3 and D5 shouldn't have counted either because the stones are in seki (not supported currently by the game).

Sorry, this situation is beyond the knowledge of the scoring algorithm currently.
