Hi guys, just wanted to know which is the best line here:

3bettor is a fish, i have only 18 hands with him and he is playing 59/6 with an AF of 1.3

I called because having only these small infos i thought foldind TP + FD is bad...but after rewiewing the hand and putting it on equilab i realized i had only 30% equity against a range of only sets, and 25% if I include AsTx. That makes me think I played poorly and should have folded flop.

Thank you for your future responses.
