The correct notation of the trill in the 1st half of this bar and all its repetitions – bars 28, 74 and 82 – appeared in the sources (not including pupil's copies) only several years after the publication of the Sonata, in EE2 and GE2. The mistake was committed by Chopin, who in [A] (→GCGE1GE2mar,→FE1FE2EE2) wrote the trill minim as a G (with a cautionary ). The error was noticed in the proofreading of FE3 (→FE4,FE5), however, at the time of performing the correction, another mistake was committed, by moving the note mechanically together with the preceding it flat, which resulted in an F. The correct text was marked in all pupil's copies.
A similar mistake, consisting in writing the top second of the main note of the trill instead of the main one, from which the trill starts in this context, is to be find also in, e.g., the Bolero in A minor, Op. 19, bar 187.

In EE there is also no wavy line after the trill.

No slur in GC (→GE1)

Slur in FE (→EE) & GE2mar (→GE2)

..

The absence of the slur in GC (→GE1) is undoubtedly a mistake of the copyist. In GE2mar (→GE2) the sign was added on the basis of analogous bars.

 before 2nd beat in the sources

 at the beginning of bar suggested by the editors

..

There is no doubt that the placement of the  sign in the sources is incompatible with the notation of [A]. However, it does not have to mean that the dynamics is valid only from the 2nd beat of the bar, as Chopin would sometimes use an older convention of placing performance indications not at the beginning, but in the middle of the scope of its validity. According to us, such an interpretation is more likely here than a literal interpretation. Similarly in bars 29, 75 and 83, which in [A] (→GC) were marked as a repetition of bar 21.

No slur in GC (→GE) & FE

Slur in EE

Our variant suggestion

..

The slur in EE could have been added by Chopin. As an editorial revision is, however, also possible, in the main text we suggest a variant solution with a slur in brackets.
