Question

Shove or 3bet?

If I go 3bte, I want to make it at least 250k. In that moment it is obvious I am not folding to MP1, I look strong. At the same time I dont want to size down and end up 3way or OOP against BTN.

...plus shove looks "weaker"

What are your thoughts? Shove or 3bet? What sizing?
Does the fact that this is 16PKO and both villains have around 100$ bounty change your decision somehow? (imo more shove happy)
