Yeah, it was precisely what a friend (Bagstone) told me. "He won"
Maybe he wasn't even doing it on purpose. I really think it's an issue worth being looked at from a developer standpoint, though. If some matches are taking 5-15 minutes, and others are taking 35+ minutes, there's probably something not working properly.
Chess has a clock, HS can have a "match clock" too =P It tells players "look, when there's an easy turn, don't troll the opponent or it will come back to bite you later on a harder turn".
