You have encapsulated yourself.
Considering the Polonaise, my argument was that using 1/4 on the black notes, you had more chance of hitting the note. Richard's argument was the I shouldn't be playing it if that was my approach.
Subsequently, working on the Op.9 No.1 Nocturne, he gave me what was initially a very uncomfortable fingering for the right hand octaves. A couple of weeks diligent practice proved he was right again.
I'd encapsulated you as well, I fear; problem now duly remedied.
Well, perhaps you should tell him how Cziffra played the notorious octave passages in that Liszt Hungarian Rhapsody now that ronde_des_sylphes has provided the Youtubed evidence!...
Ain't they always.
No, they're not always right, even if only because, as often as not, there's no such thing as right and wrong in these matters, at least in the sense that one solution fits all. For the record, incidentally, I once say Marc-André Hamelin play a scale in octaves using the same fingering as one would usually use to play a scale in thirds, but he only did this as a joke for my benefit and swore that he would never usually do it.
Best,
