May be I'm sitting on the wire. -:)
The above FEN position looks as follows:
+---+---+---+---+---+---+---+---+
8 | *Q| *N| *B| | | | | |
+---+---+---+---+---+---+---+---+
7 | | *P| | *K| B | K | | |
+---+---+---+---+---+---+---+---+
6 | *P| P | *P| | | | | |
+---+---+---+---+---+---+---+---+
5 | P | | *P| | | | | |
+---+---+---+---+---+---+---+---+
4 | | | P | | | | | |
+---+---+---+---+---+---+---+---+
3 | | | | | | | | |
+---+---+---+---+---+---+---+---+
2 | | | | | | | | |
+---+---+---+---+---+---+---+---+
1 | | | | | | | | |
+---+---+---+---+---+---+---+---+

How can a black bishop move to e5 or e7 in this position?
I see only one black bishob on c8. This bishop can not move anywhere.
Can you enlighten me please?
Kind regards
Bernhard
