Does anyone know what his range is? What are the top 2% of hands? I don't feel like working this out, but my guess is that it is limited to AAKKQQAK, and maybe JJ. AK has poor equity against this range, so calling is pretty bad. Since he plays 40% of his hands, he's a calling station so you have very little fold equity against JJQQAK. Folding might be best. The fact that you only have a 100 hand sample does not justify dismissing the data; he might actually even be tighter than this!

Oh, and if you think I'm a nit by saying this, you're wrong. I run 19/13. This is simply an exercise in math. Unless his range includes TT and AQ, then I don't see a problem with a fold.
