The slur under the 2nd and 3rd crotchets, the only one in the L.H. part in both appearances of the C
minor theme (except for b. 325 and analog.), can be considered a model entry, to be applied in all similarly structured figures. However, according to us, it is more likely that the slur was left as an inconspicuous remnant of the quest for the most proper way of marking that accompaniment. The slurs are visible both in the original version of b. 310-311, deleted in A, and in analogous b. 412-415, where the four-bar phrase mark was also deleted. On the basis thereof, one can assume that Chopin eventually abandoned the idea of slurs in this part, satisfied with the legato indication, repeated a few times (in b. 326, 412 & 428). The absence of the slur in FE (→EE) is probably an oversight of the engraver, yet taking into account the above observations, this version can be considered equivalent.
