Unless it's a super busy street with no chance of wedging in I'd take the lane next to the right-turn. Letting cars sandwich you between the right and the thru lane is a bad, bad idea, and so is taking that sidewalk in most cases. The one time that the eye contact is misinterpreted by the driver, and you forget to make sure the driver knew what the heck was going on, will be the time you get into a collision.
