A
compare
b. 17-18
Both the additional slur in bars 16-17 and the visible connection of slurs at the transition between these bars in A clearly prove Chopin's intention with regard to the phrasing in this place. The two-bar slur of AI cannot be considered to be a full-fledged variant in this situation, particularly considering the fact that Chopin did not write slurring in bars 9-16 in this autograph at all.
