Though not a flawless game, I really liked keeping the knight on g6 thanks to the h pawn.
After that the h pawn could even push further, opening the door to the ultimate square : h8
Black got a kind of "French bishop" which turned out to be off-side on the queen side and perhaps missing on the king side. I liked it how almost all the black pieces (except the DSB) were on light squares at the very end of the game.

Inspiration of keeping the knight on g6 was a little bit from a Garry Kasparov game with Queen's Gambit as white. Years ago I saw it in some annotated game, book or video, and also there it was a knight on g6.
