White: Jobava, 2727. 
Black: Carlsen, 2862. 
Event: Tata Steel, Wijk aan Zee 2015. 
Result: 0-1 in 50 moves. 
Opening: Nimzowitsch-Larsen, Indian Variation, A01. 

Brief summary. 
Tournament standing: White is on 1.5 points from 7 games, tournament rating 2507. 
Tournament tanding: Black is on 5 points from 7 games, tournament rating 2907 and has just won 4 games in a row. 
Early opening: White, 3. Nc3, is aimed at taking both players out of a battle of theory. Black chooses simple development in response, wisely avoiding trying to refute the idea. 
Mid opening: White, 8. f3, sets up a possible kingside pawn attack, but black, 8. ... h5, prevents this. Black makes it difficult for white to play for queenside castling by forcing the exchange of dark square bishops. 
Early middlegame: Black castles kingside and prepares to fight up the central files. White trades a bishop for a knight and then tries to hold the centre with his 2 knights. Black advances with, 21. ... h3, in itself not threatening, but such a pawn might offer opportunities in the endgame. 
Mid middlegame: Black trades all rooks and enters an endgame of queen and bishop against white queen and knight. The black h3 pawn now becomes an annoyance for white, the black queen must not be allowed to invade along the white 2nd rank. 
Early endgame: Black tries to probe with queen and bishop but white has a fortress. 
Mid endgame: White seeks to create unnecessary kingside complications on moves 38 and 39 in black's time trouble, not really recommended but understandable. All it does is offer the black queen an entry into the white position, the fortress was dismantled from within. 
Late endgame: Once black won a pawn, the advanced h3 pawn gave black unstoppable threats of a queen invasion. The only question remaining was wether white could find a perpetual or would the black king advance to win more pawns.
