These questions may seem strange to you if you're unfamiliar with the challenges that streamer IM Eric Rosen sometimes gives himself. For some, it seems, simply playing a normal game isn't enough. Maybe you can win, but can you win after playing your first move with the E-pawn and moves 2 and 3 with the G-pawn, thus spelling the word "Egg?" This is the mark of a true master.

This site is one of the many that relies on the Lichess API to function. APIs are basically a tool that allows different pieces of software to communicate with each other easily and efficiently. The Rosen Score website asks Lichess for games to check for the different achievements and Lichess sends them over.
