Chess with new pieces

Instructions

This is chess, but with some new pieces that can be acquired through promotion, or simply started with instead of knights/rooks. Read below to find out more about the new pieces, or read even further down to read about the rest of the chess pieces and rules of chess, Infector piece (3 points): This new piece is the infector. It replaces the knight, and is worth 3 points (although I'm not sure how accurate this is). It can move and take like a king, 1 space in any direction, except it can also take any piece that passed through its tiles on the previous turn, by moving to a tile that the piece moved through. Example: Black queen moves from h8 to h1. Infector moves from g4 to h5. Because black queen moved through h5 on the previous turn, the infector removes the black queen from the board. The infector piece cannot take pieces by moving to tiles they were on, just tiles they were moved through. The infector cannot take a knight without taking it directly, as knights can move to each tile in 2 different ways. Ranger (5 points): This new piece replaces the rook, and is worth 5 points (as far as I'm aware). It can move like a bishop, (diagonally), however it cannot take pieces while moving like this. In order to take a piece, it must move like a rook and capture a piece on the same row or file as itself (vertically or horizontally). It cannot move like a rook without taking a piece. You can also castle with this piece, just like a rook. Zombie Chess: Much like normal chess, but white starts off with extra pieces (the new ones) and blacks pieces have had their movement severely limited (pawns can't go two on first move or en passant, rooks can only go 1 in any vertical or horizontal, bishops can only go 1 in any diagonal, knights can only move 1-2 forwards or 1 back, queens move like king, who stays the same). Blacks pieces (except the king), however, replace enemy pieces with zombie pawns upon instead of moving to the attacked tile upon capture. Because zombies can amass so many pawns, zombie pawns will not promote once they reach the last rank, but rather solidify and become un-takable. The zombie queen, however, can move like a normal queen while retaining her zombie powers whenever she reaches the last rank. On your turn, Click on a piece, then click where you want to move it. You cannot move a piece if doing so will leave your king vulnerable. After you move a piece, your turn will end. The goal is to trap the enemy king (checkmate). However, the game can end in a draw if one player cannot move but also their king cannot be attacked the following turn, or if the same position is repeated on 3 separate turns, or if 50 turns pass without a piece being taken (stalemate). king (worth the game): can move or take 1 in any direction, the object is to trap this piece (AKA: checkmate). The king can move two spaces right or left if there are no pieces between the king and the rook on the back rank, and neither piece has moved. The rook will then move to the other side of the king. This is known as Castling. You cannot castle if the king is in check, or if the tile he skips is under attack. Pawn (1 point): Can move 1 space forwards, or 2, if it is on its starting square. Cannot move forwards into an enemy piece. Can take pieces diagonally forwards 1 tile. Can promote to any other non-king piece if it reaches the back rank (this is known as promotion). Can take another pawn that moved 2 squares past it on the previous move as if that pawn had only moved 1 square (this is known as en passant) Bishop (3 points): Can move and take pieces any number of squares diagonally, but cannot move/take through pieces. Knight (3 points): Can move and take 2 spaces in one direction, and 1 in another, making an "L" shape. Can move through/jump over pieces. Rook (5 points): Can move and take vertically and horizontally, any number of tiles. Cannot move/take through pieces. Queen (9 points): Can move and take vertically, horizontally, and diagonally, but cannot move through pieces.
