Diagonal pawn chess

I'm not modifying the game too much. I intend to change the rules as to how the pawns move and their respective promotions.

Setup

The set up remains the same as in the standard Chess.

Pieces

This game has all the same pieces as Chess, but the pawns always move one space diagonally forward, even when not capturing. As a result, there are no blocked pawns unable to move. Pawns do not get double moves and may not capture by en passant. Upon reaching the last rank, a pawn promotes to the piece that started on that space, or to a queen if it lands on the king's original space.

Rules

Apart from the differences in how the pawn moves and promotes, detailed above, this game follows the rules of Chess.

Notes

White : Kd3, c4 and e4 (pawns)

Black (to move) : Kd7, c6 and e6

With accurate play the game is a draw. However if black plays 1...c6-b5?? 2. c4-b5 Kd6 3.Kd4 Kc7 4.Kc5 Kb7 5.b5-c6+ Kc7 6.Kb5.. black is lost because if...Kd8 7.c6-b7, followed by b7a8=Rook

If...Kb8 then c6-d7, d7-e8= Queen
