[#help-enpassant](Illegal pawn capture)[#help-castling](Illegal or impossible castling)[#help-insufficient](Insufficient mating material)[#help-casual](No rating points were awarded)[#help-error-page](Error page)[#help-security](Security vulnerability)[#help-other-bug](Other bug)
It is called "en passant" and is one of the rules of chess.
[/learn#/15](Try this little interactive game to learn more about "en passant".)
Castling is only prevented if the king goes through a controlled square.
[https://en.wikipedia.org/wiki/Castling#Requirements](Make sure you understand the castling rules).
[/learn#/14](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.
[https://handbook.fide.com/chapter/E012023](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.
In certain circumstances when playing against a bot account, a rated game may not award points if it is determined that the player is abusing the bot for rating points.

Please do not send direct messages to moderators.
You may send an appeal to /appeal.
False positives do happen sometimes, and we're sorry about that. If your appeal is legitimate, we will lift the ban ASAP.
However if you indeed used engine assistance, even just once, then your account is unfortunately lost. Do not deny having cheated. If you want to be allowed to create a new account, just admit to what you did, and show that you understood that it was a mistake.
