There is famous Capablanca game where he sacs pawns with
check in the ending just to promote one pawn. I sac 4 pawns.

I was talking about Black having an advanced King’s Rook pawn and saying
it was no good as a drawing device if there were other pawns on the board.
This is a draw. But in the game Black had two pawns
This is a win. 1.Kf3 f5 2. Ra2 and mate next move.
