Overly Ambitious Challenge

In this custom position, the entire board is blocked, and black only has 1 move to consider until white sacrifices to try and promote the pawns on the last few files. The position is already drawn at the beginning as white can draw by 50 move rule or repetition, but the fun comes when white sacrifices a knight to try and promote pawns. Although black has a queen, either side can win or it can be a draw once white sacrifices, so the question is for white: will you take the risk of losing in order to win?
