1 not tied in 
In EE, D flat1 in bar 195 is not held until bar 196, as there is no tie and the lower note of the L.H. octave in bar 196 is also absent. The notation of GC (→GE), when read literally, results in the same version. In our opinion, by writing 8 in bar 195 under D flat tied until the next bar Chopin almost certainly had in mind the pianistically natural holding of the entire octave. This undermines the reliability of the version of EE, which most probably results from a misinterpretation of the notation of GC. In FE, the holding of the entire octave is notated in the clear, doubtless manner. Similar ambiguities occur in analogous bars 239-240, while in bars 489-490 the notation of all the sources clearly indicates that the entire octave should be held.
