1.a3 "is played by lazy people" by GM Roman in Romans lab
basically the anderssen's opening can be played by some one who is good at defence, but saying this will lead you in to the middle game quicker you are mistaken as this line is there in theory if i am not mistaken.
so in almost all variations black is better according to stockfish 6. but practically if black looses initiative white can pull a fast win.
this oopening violates opening principles to the root.
Doesnt playing 1.a3 reverse colours as long as black doesnt try 1...a6 or h6? So wouldnt it cut down the time a player needs to spend studying lines as white as he could play whatever he plays as black after the change of tempo? So doesnt 1.a3 mean more time for studying middlegame and endgame?
