I downloaded the client, went through the trouble of understanding the server and challenged a few dozen players, from 8k to 25k (set myself at 10k). Tried the automatch, responded to about ten game requests.
All denied. I regret the effort.
Now I did play. My last game the opponent continued to mark wrong captured stones. I never agreed, I won by an extreme margin, still the result was a loss. I don't see the point if such things happen.
