This is a very lively third movement. Again, care must be taken with articulation to prevent it from sounding heavy. The issue lies with the left-hand passages, but generally, I believe they can be played short and staccato. In the edition I am using, the left hand has legato markings from measures 5-6; is this the same in your editions? Passages marked with legato can be played legato or with the pedal, but in sections without such markings, for example, the left hand in measures 1-4 and 9-12, it is perfectly acceptable to play them short and detached. This will prevent them from sounding heavy.

It may depend on the edition, but where legato is marked, play legato; where it is not marked, either legato or staccato is fine. The key is that it should not sound heavy to the listener.

By the way, this third movement has some difficult sections. First, measures 39-41. The same passage appears later, so we will use this as an example. Let's take measure 39 as an excerpt. For the right-hand trill on the second beat of measure 39, there are two methods. The easier method is to play E-F#-E-F# G G G. The more challenging method is E-F#-E-D-E-F# G G G. Either is acceptable, but if possible, try playing the more difficult one. In this case, if you consider aligning the three notes E-F#-E with the left-hand G, and the next D-E-F# with the left-hand E, it becomes a triplet, but when playing at a certain speed, thinking in terms of triplets is almost impossible. This is because it would be too fast to play.

Therefore, distribute the seven notes E-F#-E-D-E-F#-G across three left-hand sixteenth notes. In this case, the final G cannot perfectly align with the left-hand G. A slight delay will occur. However, if the final G aligns with the left-hand E, it will not sound strange. Please try it.
