Last 16 of tournament and we are 13 out of 16. BB has been three betting quite aggressively but nobody else has done anything out of line.

So its a reasonably straight forward spot but I had a couple of thoughts that I hope someone can help with. I have run the above hand through ICMizer and the shove is +CEV but we only make around 3500 chips on average. Should we be looking to take any edge we can with only 12bb's or is there a threshold figure that we should be looking for. For example should we wait to make a shove that profits more than 0.5bb or 1bb or even higher.

I understand that r/f is also an option here but i chose not to because of the player in the BB who was playing back quite regularly. Overall is a shove in this spot too high risk or do we just have to push any sort of edge here?
