just to clarify
When I say "sacrifice" I mean using a weak player against an unbeatable opponent, saving our stronger player to use against their weaker player. It's an effort to split singles, rather than lose both, and there's no guarantee it will work. It's kind of like a sacrifice in baseball... one player goes down, but the team improves its chances to score.
When freak says sacrifice, he means someone intentionally losing a match they could win in order to manipulate the computer ratings.
There is a huge difference in those two.
I can't complain, but sometimes I still do. Life's been good to me so far.
