A recurring endgame trick
As a teenager my chess teacher showed me lots of chess games and examples.
One endgame type that impressed me a lot was :
The "bishop of the wrong color" and the pawn at the edge.
For example like this :
In a game today, I played against a strong player to whom I lost already 3 times in the past.
In this very game I thought I was going to lose again, but in the end I was lucky.
The well known wrong color bishop appeared !
