This is just a general question, as I'm getting confused as to alter my range accordingly to this type of situation:

Let's say BB is super nit with a full stack, and SB is a shorty with like 25BBs and the only move he makes to your raise from button is a AI re shove, and he does this like 15-20% of the time.

Do I want to tighten my normal button opening requirements here? Do I want to manipulate my raise amount to smaller raises like 3x or even 2.5xBB?

I was just was getting a little confused in a bunch of mixed stack situations tonight. I don't think I was playing against the short stacks very well.

I'm averaging playing at about 27/24 at the moment.
