Game Reviews by Rodrigo Zanotelli

"Keller, in his 10th issue of World Game Review mentions the following paradox: what if, say white checks black, such that blacks only move is to check white, but in that position, whites only move is to check black, and so on and so on."
How this would happen in checkless chess? The rules say that you can only mate the enemy king, not check him. In fact this is the main idea of the variant.

One cool variant could be made where
1-You can capture your own pieces.
2-You can't capture the king
3-Its possible to put your king in check with friendly pieces. So you need to avoid it.

In this variant both players would need to start by capturing their own

A new variant could be made. Maybe called Hivemind chess.
1-You can move enemy pieces that you are attacking.
1.1-You can only move those pieces to a square you are attacking.
2-You can't attack other enemy pieces or your own pieces using a enemy piece.
3-You can't put your king in check by moving a enemy piece.
4-Win by checking the enemy king.
5-All other rules as in chess.

A minor sub-variant of this variant I made here, can be made here:
1-All rules as in hivemind chess.
2-While controlling a enemy piece you can use this piece to capture one of you own pieces, excluding the king, as long the enemy piece end into a attacked square after the capture is done.

another idea:
'Hasbro' Monopoly chess.
1.You can spend one turn without moving to buy some square. After this turn this square will be your square. 
1.1-Your piece need to be on the square you will buy.
1.2-If some enemy piece move into this square, the piece is killed.
2-You can trade squares and pieces with the other player, by killing some of your pieces, giving some of your pieces to the other player (they will stay at the same place, but change sides) or giving some of your squares.
2.1-You can also save a enemy piece from being killed on a square or make some squares(s) safe for x turns by trading stuff.



Banker Monopoly chess.
1.Normal 'Hasbro' Monopoly chess rules apply.
2.You can sell one of your squares to the bank and you will be able to move one more piece in this turn.
