As a pianist without the technical training and experience of many other contributors, here is how I play it: The chords are played entirely with the left hand, the last chord of the 9th measure is rolled, as are the last two of the 10th. All the other ones I can reach. The right hand stays in the treble. It takes a little practice, but I think it sounds very nice when played this way correctly (hitting all the notes of the chords correctly and evenly)
