Donk/fold the river

[villains_hero]

From time to time I find myself in river spots out of position where I think the book says „donk and fold to a raise“ because the check/call approach would give away value in case it is checked behind. Unfortunately in many of these spots I have trouble doing it because a) folding the river with a decent pair feels bad and b) I fear being fooled. This is the recent experience with this phenomenon.

Villain is 29/19/2,2

30/60 6-handed

Hero thinks „Probably I should donk/fold here, but this guy is tricky, can I safely fold to a raise? Hmm, I guess I better post this hand.“
