I had a tight image at this table...
MP3 played 20/4 and 0 3b, 0 3b call(100 hands)
CO played 45/6 amd 0 3b, 0 3b call(55 hands)
Is this squeeze push to loose?

What would be the right pushing range in this spot?

It depends on whether you think you have fold equity vs MP.

If he's decent then you have no FE and should only be shoving for value. Maybe something like 55+, ATo+, A8s+, KQ

If he's bad enough to fold then A6 is a clear jam

tank you!
seems logically to me.
