All you have to do is go to the piano and start playing random keys very fast and very loud. Then when someone asks "What's all that random banging?" you can say, "That's not random banging! That's Rachmaninoff's second concerto!" They will probably believe you and be very impressed. I'm serious. I did it once as a joke.

.............WOW whats your problem

Huh? You are the one posting with a "problem"! I gave you 2 suggestions: one impressive and flashy, the other more technically challenging because you say you have better "chops' than your foe. My "assuming you can do it comment" was based on the fact that many intermediate players have difficulty with polyrhythms, and there have been many posts here on coping with this...many specifically wrt Fantasie Impromptu. Sorry my good-faith effort fell on deaf ears.

I think GP failed to understand your post. He probably interpreted "I can play this but you can't" as a direct claim about your superior technique over his. We know what you meant.

BTW, if 3 vs. 2 polyrhythm is a good trick to impress at this level, and intermediate chops is the constraint, then Debussy's 1st Arabesque would fit the bill nicely.

GP: You've missed the point of Stanza's 'I can play this you can't' statement...
There was a suggestion of two pieces - a 'Flashy' piece to impress this other person in your class... and an 'I can play this you can't' piece.... as in "I, Graded Piano, can play this piece and you, other person in my class who I want to show off to, can't"

That's what Stanza meant.

It sounds as though you are quick to jump to the conclusion that others are trying to put you down. The people here in the forum - and this person in your class. Perhaps you would be better to continue with YOUR enjoyment of music as a model for this other person - rather than engage in a competitive one-upmanship. That's never going to get the outcome you want. If this person truly does want to put you down - then no matter what you play you aren't going to impress them. So... keep playing what YOU enjoy - and enjoy the process. Leave others to do the pointless showing off.
