Clementi’s Allegro con brio, Sonata in B flat Op 24 No.2

One of my grade eight pieces that I’m working on right now is Clementi’s Allegro con brio, Sonata in B flat Op 24.  I think it is a very beautiful piece and I am thoroughly enjoying practising it.  I found that some pieces in it are difficult to play fluidly, and that  my fingers somehow seem to get stuck, or freeze at certain parts.  I have found some lovely examples below from you tube of how the piece should sound.
