Toughts?

1-Do 200 player ever bluff there ? I feel I'm too high in my range to fold but expect to be beat quite alot.
2-How would you guys play your overpairs in that spot?
3-What about the sizings ott and otr? I kind of feel like it would be better to bet smaller with at a high frenquency on turn and river(70-80% range (sizing)).
4-What if we were 200+bb effective?

Thanks
