25 NL TPTK + FL draw, villain shoves

[Cosmo26]

I played about 20 hands with villain and he seems to be tilting after I stacked him a few hands ago. So what do you think of this hand? He might have a set, but could be a hand like KK-TT / flush draw which he is not willing to lay down as well regarding our history.
So do I ever lay this down?

I'm always calling this, even more so since you think he might be tilting.

hrm, I'd call given history. The only set that really makes sense is 44, and you're flipping with A9 and A4. I'm sure he shows up here sometimes with a weaker ace/fd so I think this is an easy call.

This is an incredibly easy call.
