Black to move

(I do not understand why anyone in their right mind would play this move. Stockfish 13 @depth74(!) and Fritz 17 @depth 33 play the logical 6 a4. Houdini shows 6 Nc3, which at least stops the black pawn from moving forward. Yet the Chessbase Database shows 90 games in which the move 6 a3 has been played; 104 games feature 6 a4) 6…a4 7. Ba2 Bd6 8. Nbd2 (The CBDB shows 8 Nc3 has been played in an astounding number,53, of games out of the 65 games contained in the CBDB even though it has only scored 44%! Stockfish and Komodo both castle, while SF 310721 @depth 27 would play 8 Bg5, which will be a TN just as soon as a titled player plays it in a rated game…The only other game with 8 Nbd2 can be found below, along with another game in which 8 Qe2 was played. If you have to ask why the second game is being presented you are obviously not a regular reader of the AW.
