can I limp call off 31 BB from sb vs BB?

[Guido]

yesterday I came into a gross Spot. i played a Tournament live and it was nearing the end of day 1. the BB came new to the table and seemed to be an aggressive Fearless player.

he covered me slightly. it was folded to me 31 BB and I limped expecting a normal raise and was planning to limp - push with my A3o.

then my Plan got counterfeited. he Jammed allin after I limped .

i folded ...

thoughts?

I would fold and I don't mind the limp if you are going to be doing that HU B v B with some hands at the top of your range too but I think a 3x open is better at this stack depth.
