Great lists so far, especially the Schubert, Scriabin, Janáček and Prokofiev selections.

Schumann Op. 11
Chopin Op. 58
Medtner Op. 53 no. 2

Good call there. Medtner-wise, I was very impressed by the new Alessandro Taverna recording, he does a killer Minacciosa.

[Wanderer]

Bartok Sonata for Two Pianos and Percussion

Bartók, Sonata for 2 pianos & percussion,
Stravinsky, Sonata for 2 pianos

As much as I love these, I'm afraid they're not eligible. It's not like there's a dearth of sonatas for solo piano. 

Can I count Ravel's GdlN?

I love Gaspard de la nuit, but let's leave it for the favourite piano works thread.

[Jo498]

Mozart a minor
Haydn C major Nr 50 (60) (but I could list another 7 I think)
Schubert D 959
Schubert D 845
Chopin Nr 3 b minor
Schumann Nr 1
Brahms Nr 3

[North Star]

Schubert D. 960
Schumann no. 1
Janáček
Scriabin no. 9
Prokofiev nos. 6, 7 & 8

[Wanderer]

Well, you never stated solo piano .. and those are Super Piano Sonatas .. the music just requires more pianos/hands/fingers. 

I never stated "super", either. 
So to clarify: the prerequisites are solo piano, no more than two hands, and the word sonata in the title.

Bottom line: I wouldn't mind seeing more of your solo piano favourites. Ultimately, your list is yours to curate. Add some solo piano sonatas and we'll call the super-powered ones honorary mentions.

[Ken B]

Many Schuberts
Liszt
some late Mozart or other

HM to some Scriabin, Prokofiev

[AdamFromWashington]

Well, um, probably lots of Schubert. Actually, I could fill up the list with Schubert...

I'll pick the D. 850 and D. 960 Sonatas.

Ives' Concord Sonata.

Prokofiev's 7th Sonata.

Janáček's 1. X. 1905.

Schumann's Op. 22

And, um... I don't like making lists. Six is good.

[Madiel]

Ah. Um...

Vine No.1 - which I still ridiculously don't own a copy of despite loving it for 2 decades

Mozart K.309 (a favourite to actually play)

Mozart K.332

Ravel Sonatine

Scarlatti K.27

Schubert... probably D.960 and maybe D.845?

This is rather making me realise I don't listen to sonatas that often, as opposed to other forms of piano music. There are a couple of composers appearing in these lists for whom the sonatas aren't highlights for me - Chopin is the big one, but also Rachmaninov's no.2 is a work I know but wouldn't return to when I have things like the Etudes-Tableaux. Brahms' I don't know and I only know Schumann's op.22.

PS I did very much like Scriabin's the one time I listened to them. I think it was no.5 that particularly grabbed my attention.

Ditto.

[Dancing Divertimentian]

I had the same initial thought.

Schubert D960

Schubert D894

Liszt B Minor

Scarlatti K8

Mozart K457

Well, let's see...

1) Enescu's 3rd
2) Prokofiev's 6th
3) Boulez's 2nd
4) Mozart's K331
5) Scriabin's 4th
6) Schubert's D840 Reliquie --yes, that one!--
7) Krenek's 3rd

Just like that, in no particular order

[Madiel]

6) Schubert's D840 Reliquie --yes, that one!--

*Gasp* He's gone MAD!
