Chess Puzzles
Here you find some "interesting game positions" described in a format called FEN, which stands for Forsyth-Edwards Notation.
To play them, you need the offline version of SparkChess (flashCHESS), which supports Board Editor.
Promote to Knight
By studying databases with millions of played games, one could see that 97% of promotions have been made to Queen. It makes sense, since it's the most powerful piece. Still, are there cases where an 'underpromotion', that is promoting to Rook, Knight or Bishop would be more useful?
World Champion Emanuel Lasker presented a position in which White is in serious trouble, that not even a promotion to Queen would solve.
