It is called "en passant" and is one of the rules of chess.

Try this little interactive game to learn more about "en passant"..

Castling is only prevented if the king goes through a controlled square.

Make sure you understand the castling rules.

Try this little interactive game to practice castling in chess.

If you imported the game, or started it from a position, make sure you correctly set the castling rights.

According to the FIDE Laws of Chess §6.9, if a checkmate is possible with any legal sequence of moves, then the game is not a draw.

It is possible to checkmate with only a knight or a bishop, if the opponent has more than a king on the board.

Make sure you played a rated game. Casual games do not affect the players ratings.
