Played this game OTB against someone slightly weaker than me.
Admittedly it isn't the greatest game in the world as white doesn't play all that well, but I like how this game shows just basic ideas, i.e. bishops on good, open diagonals and a h-pawn push into the enemy kingside, lead to a crushing victory.
It's worth noting (but I didn't put it in the diagram) that the more simple 19...g5 doesn't work after 20.Be4. This was the line my opponent had analysed.
