dxe3

dxe3 is a chess move notation used in algebraic notation to indicate that a pawn from the d-file captures a piece or pawn on the square e3. The capturing pawn can be a white pawn on d2 moving to e3 or a black pawn on d4 moving to e3, depending on who is to move. In either case, the pawn moves diagonally one square toward the opposite side and the piece on e3 is removed from the board.

En passant situations are also written as dxe3 e.p. In an en passant capture, the capturing pawn lands on e3 and the pawn that moved two squares on the previous move is removed as if it had been captured on the square it passed over.

Strategic considerations: dxe3 often undermines a central pawn structure, opens the e-file for rooks or the queen, and may create a passed pawn or new tactical possibilities. The resulting pawn structure can influence king safety, piece activity, and the flow of the middlegame or endgame. Whether the capture is favorable depends on the position, the presence of defenders on e3, and the potential follow-up moves for both sides.

Example: If White has a pawn on d2 and Black has a piece on e3, White can play dxe3, placing a white pawn on e3 and removing the Black piece. Conversely, if Black has a pawn on d4 and White has a piece on e3, Black may respond with dxe3, capturing that piece and placing the pawn on e3.
