Bishop Endgame – Find the Best move

Kiviharju – Ehrnrooth, Finland  1982  

 Black to move (Solution will be posted tomorrow)

This position is taken from my E-book about endgames with bishops of opposite color:

The book is formatted for electronic readers and can be read on devices of various sizes, from tablets to phones. The free sample includes 3 thoroughly annotated games and the full book comes with dozens of training positions to help develop a good sense for positions with bishops of opposite colour.

I think ebooks are a very promising media for chess content, and would be very interested to hear what you think about it.
