Infect chess and delayed Flintenschach


Dear chess friends,

I want to present to you two new fairy conditions that I came up with:
1. Infect chess

- A piece under certain stipulations can infect an opposing piece. Special rules for infected pieces apply.
- A piece can be infected only if it was attacked since the last turn. A player skips a turn to infect a piece. Infecting a piece adds one infection counter to that piece.

Rules for infection counters:
- 1 infection counter denotes the incubation period. No special rules apply.
- 2 infection counters denote the sickness period. The opponent may remove one infection counter at the end of the player's turn (i.e. White after Black has moved) to infect another piece that is guarded/seen by that piece.
- 3 infection counters denote a deadly sickness. If the infected piece is not the last royal piece, it dies. If the last royal piece has three infection counters and no special rules apply (such as Circe Rex Inclusive), instead of the piece dying, the player loses the game.

Special cases:
- A king can castle under certain circumstances if it has not yet moved. However, he can not infect a piece that is two squares away, even if he could castle to that square.
- A king normally can only be infected by a piece seeing him having two infection counters. If kings can remain in check for fairy chess reasons, an infection may be transmitted directly by the checking piece, provided that it would otherwise be able to capture the king.
- A piece that is to be infected does not have needed to be attacked by the same piece it was attacked by at the last turn. For example, a white bishop on e7 and a white bishop on e6 see a pawn that moves from f7 and f6. White can infect the pawn by skipping a turn, even though the attacking piece has changed.
- An infection can not be given if the piece was not attacked at the end of the previous turn. This is important for Madrasi and such. Pinned pieces may infect only pieces they could capture normally, i.e. the pin rules apply also to the attack check for infection.
- A promoted pawn keeps his infection counters after promoting. A reborn piece loses all infection counters. This also is true if the reborn piece is the only royal piece and has died from infection.
- An infection can happen en passant under normal en-passant rules. In this case, the pawn that infects the other piece does not move either.

- Infection counters can't be removed by the player of the infected piece. He can't infect his own pieces either. This is also true if he uses an opponent's piece with two infect counters to infect another piece.


tl;dr: A piece can be infected if either it was attacked since the last turn. In that case a turn is skipped to infect the piece. Or it is infected at the end of a turn if the opponent has put two infection counters on a piece of the same color that guards it. In that case, one infection counter is removed from the guarding piece and added to the guarded piece. No turn is skipped. A piece with three infection counters dies. This can't be delayed. A king with three infection counters does not die, rather the game is lost, unless fairy chess rules apply that stipulate conditions at which a king can actually be captured.



Delayed Flintenschach:

Normal Flintenschach rules apply, except:
There are three types. In type "standard", a player shoots instead of moving. In type "pre", a player shoots and then moves. In type "post", a player moves and then shoots. In the case of types "pre" and "post", only the piece that moved last can shoot. Instead of shooting, kings and pawns use their scepter/bayonet for a close range attack.
Where a shot was fired, the piece shot at may move or the line to that piece might be interrupted by moving another piece in-between. At the end of the opposing player's turn, that shot resolves. For example, if a queen on f3 shoots at a pawn on b7 while Black has pieces in the beginning position, Black can move the pawn, but then the rook a8 is destroyed by the shot. Black can move Pd7 to d5, then Pd5 is destroyed but not Pb7. Black can similarly move Pc7 to c6 or Sb8 to c6 who are then destroyed.

If at the end of the turn, there is no piece in the shooting trajectory, no piece is destroyed. Similarly if the king or pawn use their weapons, the piece must remain where it is to be destroyed. If for some fair reason another piece goes to that place, all pieces on that square are destroyed if they could be captured.

A piece is only destroyed if it could be captured, ignoring pinning rules, at the end of the turn. If it somehow becomes indestructible but is on the same square, the bullet will not destroy it.




I believe the both fairy conditions are more interesting for practical play than for composing.

While shoot idea is interesting, the infection idea is too complicated and anyway sickining imagination
