Thanks for taking the time to look and I'm grateful for any posts/advice/info

2 5 live game LV
9 handed

My first hand at the table so my reads of people's play is limited to how they look.

ep opens 15 ( he is 40ish and dressed casual. I would think with that sizing he would have a range made up of week hands with some strong hands) I raise 45 ajcc mp. Im raising ro isolate and increase the strength of my range. he calls j45cc. he chk. I bet 40. he chk raise 160/560.

My standard is folding here with no info. Is this incorrect?
