Riding up the right side is generally a very bad idea and puts you at risk of a right hook. Drivers aren't expecting to see a bike there.
I'd take my place in line. If the road is wide enough to share the lane, then once traffic gets moving you can move toward the right. If it is not wide enough, keep your place in the middle of the lane, and cars can pass you using the left lane when it is clear of oncoming traffic.
Here's a really helpful and well done video that demonstrates "taking the lane" and why it is a good idea any time the lane is not wide enough to share.
