After running a half-marathon (Port Perry, ON, Canada), I was impressed with the experience of being cheered along by spectators, fellow runners, and water/aid volunteers.
This chess game is based on being cheered! So whenever a Cheer is on a piece's row, that piece is boosted to allow better moves.
 
 
Description:
All pieces all boosted by the sideline Cheer. The Cheer only moves ahead one square after each move. When a side's Cheer is alongside, that row's pieces can perform extra moves.
 
Besides a piece's own moves -
A Pawn takes on Knight moves,
A Knight takes on Bishop moves,
A Bishop takes on Rook moves,
A Rook takes on Queen moves,
A Queen (only gets King moves),
A King is allowed all moves (Queen & Knight)
The Cheer can not be captured or blocked, consider it 'off-board'.
 
Object:
Besides Checkmate, another goal is for the King to cross the Finish line up ahead; no defensive blocking is allowed inside the opponent's finish area.
