Power Absorption Chess
Play starts exactly as in standard chess and with the same rules except as noted.
The idea is pretty simple but the game will become increasingly complex.
Whenever a capture is made, the capturing piece abosorbs the power of its victim, a bishop capturing a knight becomes a bishop-knight, a rook taking a bishop becomes a rook-bishop
which is a queen, and so on. If a knight captures a pawn, it becomes a knight-pawn
and can move and capture like a pawn and also promote to another piece if it reaches the backrank.
Personally, I find this game to be much more interesting than the CrazyHouse variant that is played on internet sites.
A piece-pawn (knight-pawn, bishop-pawn, rook-pawn, bishop-knight-pawn etc) can carry out en-passant only under the usual conditions.
A piece-pawn must move like a pawn from the 7th rank to the 8th to promote. A piece-pawn can combine its existing powers to that of the newly
promoted piece which can only be a queen, rook, knight or bishop. Thus a queen-pawn can use its pawn component to promote to a
knight and result in a Queen-knight! Note that the pawn component is replaced by the promoted piece component so a knight-pawn for example
becomes a queen-knight (taking the maximum promotion of pawn to queen).
- The King's Absorbing Power:
A king can capture a bishop and become a KING-bishop now having the powers of a bishop. Similarly for rook, knight or queen.
A king with the power of a pawn (KING-p) still moves the same way but if it reaches the enemy's back rank it is promoted to a KING-Q! That is a king with the powers of a queen.
Note that in some special circumstances a king CAN CHECK ANOTHER KING!!!
The king doing the checking (just like in the rules of chess) cannot put itself in danger when doing so.
Therefore it is impossible for a KING-Q to check another KING-Q. BUT a KING-Q can check a
KING-B if it is not doing so on a diagonal, since the K-Bishop can only move and attack along the diagonal.
Similar applications to a KING-Knight (KING-kt) or a KING-Bkt.
One more limitation of the king-queen, King-rook, and king-bishop: The king cannot travel over or deliver check over any squares that are controlled by the enemy. Thus a king-bishop cannot give check to an enemy king if any of the squares it needs to travel over are controlled by an enemy piece. Note that a king-knight will not be limited this way, since it can leap over the squares.
For home use you just need a pencil and paper to record the current power of your king - no need for all the separate pieces for each king configuration.
- Absorption is optional: -
There are some cases when it would be disadvantageous to absorb the power of the victim, for example, if forced to exchange pieces,
then the enemy's recapturing piece would absorb even more power.
Visualize a scenario where you take a knight with your bishop and your opponent recaptures with a bishop.
If absorption is compulsory, then your bishop becomes a bishop-knight and your opponent's bishop now becomes a bishop-knight as well. Howerver if optional, then your opponent will not gain from this exchange.
- A piece capturing a similar piece absorbs nothing extra.
- Note that a rook capturing a queen becomes queen!
- A king cannot be captured as in normal chess so no piece will gain his power. However the king CAN gain the powers of any other piece!
Rook-Bishop - This piece is the same thing as a queen! Resulting from a rook capturing
a bishop or vice versa. The resulting power is that of a queen!
The new pieces
Rook-Pawn: resulting from either a pawn capturing a rook or rook capturing a pawn. Note that this piece can now capture one step diagonally as a normal pawn does. Landing on enemy's back rank promotes to a queen or rook-knight (pawn promotes to knight and result is a rook-knight).
- Rook-Knight: resulting from knight capturing a rook or vice versa.
Rook-Knight-Pawn - this is a rook with the powers of a knight plus pawn - can result from a Rook-p capturing a knight or a Rook-kt capturing a pawn. Promotion could be to a Queen-kt!
Bishop-Knight: - when a bishop captures a knight or vice versa. Has the powers of a bishop and a knight!
- Bishop-Knight-Pawn: resulting from any combination of captures involving bishop, knight, and pawn.
Same as bishop-kt except that it can now move forward 1 step (it can only back along the diagonal and as a knight move) and promote to a queen-kt.
- Bishop-Pawn: if a bishop captures a bishop-P or a pawn or a pawn captures a bishop it become a bishop pawn. This piece is very important. Now the bishop can make one step forward (not backwards like the pawn) and promote in the back rank. Effectively, the bishop can now change its diagonal.
Opening play between evenly matched players will be a struggle by each side to upgrade their bishop
or their knight by capturing a pawn. A pawn or two can be sacrificed to recapture with a knight or bishop.
- Knight-Pawn: A knight that can move 1 step forward and capture 1 step diagonally like a pawn. Resulting from a knight capture pawn or vice-versa.
The NEW chess openings will feature a struggle where each side will try to updgrade their knight to this piece.
Queen-Pawn: The new power does nothing to supplement the existing power of the queen, but it could promote
to a stronger piece power - the queen-knight by promoting the pawn to a knight.
- Queen-Knight: the strongest piece possible!
- Queen-Knight-Pawn: has no added value to the queen-knight except for an unusual application of en-passant. There is no promotion possiblity.
- King-Pawn: The new power does nothing to supplement the existing power of the king, but it could promote
to a stronger piece power.
- King-Knight: A king that can also move like a knight
- King-Bishop:A king that can also move like a bishop
- King-Bishop-knight: A king that can also move like a bishop or knight
- King-Queen: A king that can also move like a queen
- King-Rook: A king that can also move like a rook
- King-Queen-knight: A king that can also move like a queen or knight
- The king can also add a pawn's promotion power by capturing a pawn to its existing powers above.
e.g. King-Knight-pawn, King-bishop-pawn
Special Handicap Variation!
The new rules allow for some interesting handicap play. The stronger player can have more restrictions than the other. For example he/she cannot combine powers with pawn or combine powers of a queen. A severe handicap can be a strong player forced to play regular chess with regular pieces while the other uses the full absorption powers available! This is a wonderful handicap system that is sure to create hours of fun between unequal players.
How to create your pieces
To create a piece pawn - some sort of crown or perhaps a base pedestal should be attached to the piece.
For example, I can place my chess piece (queen, knight, rook) on top of a draughts piece to create a Queen(or knight, bishop, rook) - pawn.
We need special pieces (though we can home cook these too) for
