I hate these spots against massive fish

[Daddy Warbucks]

Villain is 81/0/0.9 over 300 mined hands. I've never played with him, and his AF is obviously low, but he's been donking a ton of flops this session, or he'll call flop and donk any turn. I've had to surrender a ton of pots to him because he keeps putting pressure on me when i have air. Are you happy to stack off here, or whats a better line?
