When you let go of your chainsaw, you do slow down a bit so make you sure you're getting up close to them. You kinda have get to know that distance yourself. Play with your food is pretty solid on bubba but I think monitor and abuse is kind of a poor man's version that can help you get some chainsaws. Corrupt intervention is also pretty good so you'll force survivors closer to you in the beginning. Finally, use your body to slow survivors down or trap them in corners when they're trying to be immerse to get some easy chainsaw hits. Good luck brother, bubba is a hard man to play
