Villan here has been very aggro at FT so far, putting pressure on short stacks and shoving frequently - essentially playing quite well as far as I could tell, but definitely shoving relatively light a fair bit.

Bearing this in mind, I think that although he's showing as 26/24 over 100 hands on my HUD, he's likely to be shoving closer to 40% of the time here and so I wonder if I have a case for calling him off with 55?

My main concern - besides how 55 might fare against his range here - is the 3 players still to act behind me. Is ithis actually an easy fold in this spot, or what factors should be considered?

Even if the other 3 players have folded already, I'd still fold.
We can do better here than take a very small +cEV spot.
88 would probably be the lowest pair I go with. The villains left to act don't make a huge difference with this stack setup. They'd need monsters to overcall, even if they're not thinking players most would recognise this.
