King Support Chess
This variant is intended to be less drawish than orthodox Chess. It features the support of pawns by the King, allowing a supported pawn to capture orthogonally forward also. That gives more possibilities to break up interlocked pawn structures and makes it more difficult to block a passed pawn. Thus it can be expected that several positions that would normally be drawn are now decided.
Also this variant has a better rule structure, by replacing en passant capture and castling by rules that make the set of allowed moves independent from the past moves. The position alone determines what moves are legal, and the past moves are relevant only for the repetition rule and the 50 moves rule.
Rules
Same as orthodox Chess, with the following exceptions:
A pawn can make a double move only if the square to leap over is not attacked by an opponent's pawn. With respect to this rule, a pawn is always attacking the squares diagonally in front of it. This rule makes the en passant capture obsolet.
A pawn that is orthogonally or diagonally adjacent to the King of the same colour may capture to the square orthogonally in front of it. It may not make a capturing double move.
Castling is replaced by the King swap: If the King of a side is on the origin square (e1 for white and e8 for black), then the King kan swap places with a friendly piece on the same row, if no other piece is in between. This can be done even if King and participating piece have previously moved, what also means that a side can make the King swap more than once in a game.
