Any alternative lines on this one? As i see it this is the only way to play it given the betsize?

Hand2:
FI: 55/13/2

Hmm his donk bet on the turn is cinda strange if it would have been agains some regular i might push this turn (what you think about that?) but agains a superfish like this i think i can get paid off if i hit i i dont like pushing because you newer know what he might be calling with.
Is it a must to shot the river when i checks as always with fish one hates to bluff them.

Thanks for any info.
