FAQ (In all these scenarios, please request a TO's assistance so we're aware of what is going on): Q: My opponent is lagging, what do I do? A: All cases of heavy lag will require that both players do a Speedtest. You can do one here: http://beta.speedtest.net/ After doing the test, please take a screenshot and give it to the TO who came to handle your case. If it's revealed that one of the players has a significantly weaker internet, then the player with the stronger internet is given the choice to either continue the set out in lag or take the win. If both players have adequate net, but one is located overseas, then both players must come to a conclusion as to whether or not they want to continue, but preference in the long run will most likely be given to the non-international player, due to the high possibility of lag with other players in the tourney.

Q: My opponent disconnected in the middle of the match! A: This is taken from the rules for PG Key and I think it will suffice here too:

"If a player disconnects, the player who disconnected can reconnect at any time if their issue is resolved. Disconnects will only qualify for a rematch if the issues occur within the first 30 seconds of the game. If someone disconnects maliciously, the player who disconnects forfeits the set."

This is generally for the sake of time and ensuring the bracket runs smoothly.

Q: My opponent is telling me to wait because they have something to do. A: If this happens, please alert a TO so we are aware. Usually, if one part of a bracket is being held up, we can usually locate it easily, but that only happens after the fact.
