Thank you in advance for any helpful information.
There are a lot of threads here on slow kitchen drains. Try the search feature in the menu bar. You'll find lots of methods, but your BF is wrong. Pressure has nothing to do with it. Drains are designed for gravity flow not pressure.
My guess is your snake is too short. Oh, and throw away the draino. It's dangerous to you and your pipes
