See this corresspondence game:
I submitted the game for LiChess computer analysis - It told me that
45. f5 was a mistake
I disagreed with the engine and let my local Stockfish sit for a few hours on the position (depth 45).
It came back with f5 being the best move +0.9 after all and Rc7 being 3rd best at +0.2 - a 70 centipawn difference, so I would call this an engine blunder.
The moral to the story is don't always take LiChess computer analysis for granted - think for yourself.
Cheers,
Andy
