Anti K?ko Chess: a move is legal only if the arrival square is NOT adjacent to any piece, this applies also to the capture of king.
K?ko Chess: a move is legal only if the arrival square is adjacent to any piece, this applies also to the capture of king.
Einstein chess: every time a piece moves (without capturing), it "loses energy" and transforms itself ("is demoted") into a smaller unit, one step down the ladder from Queen to Rook to Bishop to Knight to Pawn. Every time a piece captures, it gains energy and   transforms itself ("is promoted") into the next bigger unit. Kings do not transform. A capturing Queen-move or a non-capturing   Pawn-move does not lead to any transformation.There are no promotions. So that you can have pawns on the 8-th rank   (where they are stuck). You can also have pawns on the 1st-rank (after a non-capturing Knight move): these pawns can make a single, double  or triple step forward. After a double or triple step,   they can be captured en-passant by an enemy pawn on the 3rd or 4th rank.   After a triple step, en-passant capture can take place on two different   squares!
