Winning with the wrong bishop

A copy of "Chess Endings: Essential Knowledge" by Yuri Averbakh landed on my doormat on Saturday and I can't put it down. I'd love to be able to say it was simply revision, but, despite a lot of years playing chess, I'm still learning new things in the 'simplest' positions.

3 Bf5! Kf7; 4 Bh7! Kf6; 5 Kf4 Kf7; 6 Kg5 Kf8; 7 Kf6 Ke8; 8 Kg7 etc.

Back in 1984, in his column in the short lived Chess Express, John Nunn showed an ending from Paulsen - Metger, Nuremburg 1888 that combines both of the above themes. Paulsen played wrongly and only drew:
