b. 234

composition: Op. 35, Sonata in B♭ minor, Mvt I

Slur in GC, FE (→EE) & GE2

No slur in GE1

..

The absence of the first slur is certainly an engraver's mistake, corrected in GE2.

b. 234

composition: Op. 35, Sonata in B♭ minor, Mvt I

    in GC & EE

   in FE

No pedalling in GE

..

The absence of the last  sign in FE is most probably an oversight of the engraver of FE (the sign was added in EE). We also regard as an undoubted mistake the total omission of the pedalling in GE (cf. the note on the accent).

The notation of A suggests that Chopin wanted to place the  signs after the bar line, hence at the beginning of bars 235 and 237. In GE1 (→FEEE) it was performed only for the second time, whereas in GE2, which was changed in GE2 to a standard notation with  asterisks at the end of bar 234 and 236.

b. 234

Long & short accents in A (literal reading→GE1)

Short accents in FE (→EE) & GE2

Long accents suggested by the editors

..

The first two accents in A (→GE1) are clearly long, whereas the next two look like short ones, which, according to us, is an inaccuracy – see bar 226. Both accents are actually written after the note, which was one of the manner of writing long accents in Chopin's previous pieces – cf. bar 230. It is also worth mentioning that the accent on the fsemiquaver played in the L.H. is even shorter. Unification of the accents in the remaining editions is an arbitrary decision of the engravers of revisers.
