HI, I am just slowly transitioning from nl to plo, so I apologize for this simplistic question, this is my 3rd hand at the table so no reads, I am just wondering what size to bet in this spot, is my hand strong enough that I want to bet small to induce raises? do i want to be betting small w my whole range here or do we just pot it?
thanks!

I'd bet 50% pot or so to induce some floats..

Depends of your 3bet% if you're familiar with some player on pot, but I would prob pot it.

u should prob just pot it unless ur ever b/folding here which i doubt u do....at least i think that would be the only reason to bet smaller and not to induce
