If I draw an unrated player, will I lose/gain rating? (online USCF)

Recently, I drew an unrated player in the first round of a tournament. It was online USCF rated. I'm not sure why I chose the KID against him, one of the most drawish openings. He chose the saemisch variation, which is even more drawish. The rest of the tournament, he lost one game and drew one. I think his rating will end up at something around 1100. My rating as of the time which I'm playing the tournament is 1239. Will I lose rating? My online rating is P[24], so since I have one more provisional game, the first round of the tournament would be that game. Two things. Would I lose rating? About how much would I lose?

I don't know how USCF ratings work, but I do know that if it's FIDE rated, you don't gain or lose any rating points against unrated players. They effectively pretend the game never happened on your end.

Yes, you could potentially lose rating, but it depends on what your opponent's rating gets initialized to. If they do well enough to get a high initial rating, you may not lose any rating; of course, events are rated, not individual games (unless that's the only game you played) so how you do in the overall event versus your expected score will be the deciding factor.

oh ok

So the events are rated by how you are expected to do vs. how you actually do? Right?

Because if so, that would explain why my rating just jumped so high despite my mediocre performance in an event over the weekend.

i bet I'm going to lose rating.

very cool

Essentially. 

are you sure about it

yes
