50NL Blind on blind

Hi guys, nice to be back. Took some time off and been grinding it up on Stars. Been meaning to post some hands for awhile, time to get started! This is from my first session moving up to 50 NL. I guess my question here is how much do you open up ranges blind v blind? Villian is very aggressive, that's about my only read on him. I'm playing about 23/17/2.3 fwiw.
