We both offered (IMO) adequate availability, but they didn't line up at all. Happy to be flipped.
"it'd be rude to only give your opponent times that are good for you and force them to play on their laptop while herding cattle in order to get the game in!"
Which is basically what's happening, as my opponent went from "I'm free all day pretty much"
to "only 3 am - 7:30 am"
Of course he'd be happy to flip the match. Claims that he gave adequate availability, but he changed it from being free all day to only being free during four infeasible hours for me. If this does end up getting flipped after me clearly trying to schedule and receiving little effort in response, it'd show pretty poor hosting.
