JudgeBot is a computer program that monitors every game in which your opponent disconnects. If JudgeBot determines that you are clearly winning, it will award the win to you in about 30 or 40 seconds! You will receive an ICC message and the game will appear as a win in your history. More info in "help JudgeBot".
If you do not receive the win, it's because JudgeBot didn't think you were clearly winning.
If you still think you are winning, and your opponent won't resume the game with you, you can request an adjudication.
Under normal circumstances, you must allow your opponent seven days to resume the game.
Each time you logon, type 'resume' in the command console. Or go to your menu above in ICC for Mac/Windows: View > My adjourned games.
Right click on a game and choose 'resume' This will challenge your opponent to resume the adjourned game. (The menu also has options to offer your opponent a draw, abort or you can resign the game.)
If your opponent never logs in, or refuses to resume, then you can request the game be adjudicated as a win, draw, or an abort.
Right click on a game and choose request-win, request-draw or request-abort
After issuing the request command, please be patient. There are hundreds of games sent to the adjudicate judge each week.
