The mark visible in A1 over the 2nd and 3rd quavers in the 2nd half of the bar is probably a slur. At the same time, it seems likely that, taking into account the partially draft nature of A1, it is supposed to mark a half-bar slur, which would be natural in this context (cf. b. 22). This figure, just like all the similar ones, is encompassed with a half-bar slur also in CB. In the main text we do not give this slur, omitted by Chopin in [A2] (→CJ,CK).
