Wow!

The important thing to understand is that two pawns vs zero pawns with opposite
colored bishops is winning if the pawns have at least two files between them.

Here, black is able to make the second passed pawn on the kingside by first
putting all his pawns there on dark squares - f4, g5 & h4.

The bishop sacrifices are cool - but maybe not necessary.
