Bottom two on monotone flop OOP

[Alchemist]

My first HE post. My experience lies in O8 and Stud/8 but since I like playing HORSE, I tolerate the HE rounds. I've read maybe half of SSHE but I have a hard time wrapping my head around the game, so I often find myself lost in hands and tend to shut down when unsure.
