the best line here is certainly to call on the flop. We fold to any obvious danger card that completes draws, however beyond that we have to decide if we like our hand or not vs opps range. Standard line now seems to be that we c/r all in on the turn or just push over a turn bet.
A draw could pot this turn and push weak/tights off AA and as noted why would a set pot this turn, it folds so many weak hands. Without opp having a strong read we have a big overpair we like, potting the turn looks suspiciously like a draw to me.
Added bonus here is position in that we can evaluate whether opp wants us to call here or not. What does $26 do here and for the river that $15 does not?
