A2xa2

A2xa2 is not a recognized form of standard chess notation. In algebraic chess notation, a capture is indicated by the moving piece’s letter (N, B, R, Q, K) followed by “x” and the destination square, for example Bxa2 or Qxd4. For pawns, the originating file is shown before the “x” (for instance axa2 or exd5). The string A2xa2 does not conform to this system because “A” does not designate a valid moving piece, and the notation would imply a capture onto the square a2 in a way that the standard rules do not support.

As a result, A2xa2 is typically interpreted as a typographical error or transcription artifact rather than a legitimate move. Possible sources include optical character recognition (OCR) mistakes, case-mismatch issues when converting from one notation system to another, or simple human error in recording a game or puzzle.

In practice, the intended move could have been something like Bxa2 (a bishop captures on a2), Qxa2 (a queen captures on a2), or a pawn capture written as axa2 (a pawn from the a-file captures on a2, such as from a3). Correcting such an error helps preserve the accuracy of game records, databases, and instructional materials.
