bxc6

bxc6 is chess notation used to describe a pawn capture on the square c6 that originates from the b-file. The move indicates that a pawn currently on the b-file moves diagonally to c6 and captures an opponent’s piece or pawn that occupies that square. The designation does not specify the color of the pawn; it simply shows that the capturing pawn comes from the b-file and lands on c6.

In standard algebraic notation this capture is usually unambiguous, because typically only one pawn on the b-file can reach c6. If the capturing move is made en passant, it is written as bxc6 e.p.

Setting aside specifics of color, a pawn arriving on c6 affects the central and queenside structure. A pawn on c6 can exert control over the d5 and b5 squares and may become a focal point for attack or defense. The capture often alters pawn chains, and in some positions it may produce a lasting strongpoint on the c-file or invite a recapture that creates doubled or isolated pawns for one side.

bxc6 appears in many openings and middlegame structures whenever a pawn on the b-file encounters a piece or pawn on c6. It is not a move by a knight, bishop, rook, or queen; those would be denoted Bxc6, Nxc6, Rxc6, or Qxc6, respectively.
