Anderssen's Opening [edit]
1. a3 [edit]
Named after the German chess player Adolf Anderssen, who played this opening a few times against Morphy. This is a waiting move that doesn't do anything useful in itself, although it allows white to play b2-b4 and move the dark-squared bishop to b2. In this sense, it can be viewed as a reverse St. George Defence (1. e4 a6) with an extra move.
There are a variety of ways for black to respond to this move, including:
- 1...e5 or 1...d5 - The game can transpose into lines similar to the Sokolsky/Orangutan Opening (1. b4) should white eventually play b4.
- 1...g6 - This can be annoying for white if he was planning to play b4 and Bb2 because the long diagonal is now contested.
- 1...c5 is a relatively unexplored option.
