and as for favorites, Op. 101 and 109, the latter despite the mysteries of the last variation. I think Richter has been quoted as saying that people talk about the difficulties of the Hammerklavier but Op. 101 is just as tough. Probably not quite but I certainly feel the bars that have his attention. Waldstein, Pastoral, Op. 14#1, Op. 78. Wow. Richesse.
