A genuine question. I always thought it was 32, and have 3 large red volumes on the piano which contains them all (I play 5 or 6 of them). However, R3 has just been talking about Andras Schiff playing a cycle of all 33 Beethoven sonatas. I can only assume that someone has recently discovered another one, but Wikipedia, normally quick to respond to authentic innovations, only gives 32.
I don't think R3 were referring to this offering, originally by Dudley Moore, I think.

I think I will have to send an email. This is not the first time recently I've heard mention of 33 Beethoven sonatas.
