1...a5
Instead of developing a piece or contesting the center, Black plays in similar fashion to the Ware Defence. This move is a rare response to 1. c4 and hasn't been seen much. Black may want to develop their rook to a6 or march their a-pawn down the board to ruin White's queenside.
White can choose from a variety of responses, such as:
2. d4, pushing a central pawn to take the center for free
2. Nc3, developing the queenside knight
2. Nf3, developing the kingside knight
2. g3, preparing to fianchetto the f1 bishop
2. b3, preparing to fianchetto the c1 bishop
