Promoting Your Pawns:
The concept here is that, when you have a pawn majority on one side of the board - or 'Passed Pawns', those pawns must be pushed closer to the promoting square! (with care). In the example below, white has a pawn majority on the kingside and the black king is too far away to reach those pawns. White should waste no time in pushing those pawns down the board, because eventually after a pawn-pawn exchange occurs, white will still have a remainder of one pawn which will go down the board and promote!
