Have you ever tried memorising any part of this with eyes closed? I call this 'dark memory' It really makes you cencentrate anyhow!
You're right! Prokofiev played it the best - naturally! It sounds like the music Alfred Hitchcock would have used in one of his scary movies like Psycho! Don't feel sad. You'll be playing really well by the end of the project! Maybe not like Prokofiev - but close!
Actually, the general consensus is that Richter played it better than the Prokofiev!
