You can have a look 🙂 retrograde analysis is a method of determining what moves must have been played to reach given position. It can be a problem itself or you can encounter it while solving a 'normal' chess problem. E.g. you need to know if castling is available and you have to analyze possible precvious positions. But on the site you'll find much more than that.
edit: you managed to give four post before I finished mine!!

I've just discovered this: http://www.janko.at/Retros/index.htm
Maybe someone would like it as much as I do.

Retrograde Rule of Thumb #1: Always consider the en passant rule, as it is a favorite nuance of retrograde composers, and it is easy to forget in retrograde mode.
Rule #2: Underpromotion. 'Nuff said.
now I'm really into retractors. you can play a game of chess backwards!
