@_36darshan, if black pawns moved upwards how could this be difficult for white to make a draw?
This is a famous study by Richard Reti which shows how amazing chessboard geometry is and it is possible sometimes to stop the passer chasing it from behind.
Dont know how to put the coordinates :) white king is on h8..and the black pawn is on h5 moving away from teh white king ..White to play for a draw..
