Event #85 Loyal Knights

Condition: At least 1 knight for each player.

Both players adjust which direction their knights are facing. First the player that started the event chooses the directions of his knights, then the other player chooses the directions of his knights. The directions must be facing either a line or diagonal and a player may choose different directions among their knights.

The knight can change the direction they are facing any time they move. They can also spend a move standing still to change direction. The direction of the knights are part of the 3-fold repetition rule.

Whenever a piece would become captured that has an allied knight facing it, then the knight and the piece to be captured will switch locations and the knight becomes captured instead. If several allied knights are facing the piece about to be captured, then the player making the capture decides which knight will switch location. A piece that has an allied knight facing it can not be checked/checkmated.

If a piece reaches a promotional square when their position is switched with a knight, then they will not promote. However, they can stand still on the promotional square as a move to promote.

As a move a pawn can move 2 spaces forward on the first or second rank regardless if they have previously moved or not.

The blue arrows indicate the different directions the knight can face.

Example 1:

White plays Nf3 and changes direction towards the d1 square.

Example 2:

White spends a move to change the direction of his knight towards h4

Example 3:

Black plays Rxh4. Whites knight is not looking at the h4 pawn since there is a pawn in the way. Nothing special happens.

Example 4:

Black plays Rxg4. Since the knight is facing the pawn on g4, the knight and pawn switch positions before the capture is made resulting in the position below:

Example 5:

Black plays Rxd4. Since white has several knights facing d4, black chooses which knight will switch place with the pawn. Black chooses the g1 knight.

Whites pawn on g1 can move up to 2 squares forward later in the game if it wants to.

Example 6:

Black plays Rxh2. Since whites knight is facing a2, the pawn and knight switches positions before the capture is made.

Whites pawn does not promote when black made the capture. However, now white can spend a move to promote the pawn.

Example 7:

Black can not play Rxd8 or Nxd8 since that would result in black being in check by the queen after it switches place with the knight on h4. Black is checkmated.

Example 8:

Here black is not checkmated. Black plays Kg8. This is allowed, since if an allied knight is facing the king, the king can not be checked/checkmated.

White plays Qxg8+. This causes the king and knight to switch positions before the capture is made.

And now, black can play Rxg8.
