1. e2e4 Because I normally like to start Chess960 games with harmonic moves that open the way for a bishop or queen, my favorites in this position are 1.e4 (played in two games) and 1.b4 (which was not played, but which can transpose later if White plays e4). Two games in this round started with 1.c4. 1... e7e5 An important point for Chess960 opening theoreticians (I don't know how many there are, if any) is knowing under what circumstances repeating the same moves as your opponent is a good strategy. 2. b2b4 A harmonious move, as it opens the way for the bishop and the rook supports the pawn. 2... b7b5  3. g1h3 [%c_effect h3;square;h3;type;GreatFind;persistent;true] As we have seen in previous analyses, this is the best home for the knight. 3... c8e7 Carlsen wants to bring the knight to g6 or c6. 4. f2f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] 4... e5f4  5. f1h1 Black's king is in an awkward situation, face to face with the white rook. Black needs to quickly prepare castling. 5... e7g6  6. d2d3 Protecting the e4-pawn. 6... d8f6  7. a1f6 It's hard to say if this is better than the immediate capture on f4. 7... g8f6  8. h3f4  8... e8e5  9. e1g3  9... b8e8 [%c_effect e8;square;e8;type;Inaccuracy;persistent;true] Black's rook will be far from the weaknesses of the queenside, and this will be exemplarily exploited by Firouzja. There are two better alternatives, and the game is close to equality in both cases. 10. f4g6  10... h7g6  11. g3e5  11... e8e5  12. b1b3 [%c_effect b3;square;b3;type;GreatFind;persistent;true] A magnificent move. The white rook causes Black a lot of discomfort. First, it will attack the a-pawn and then the c-pawn. 12... a7a6  13. b3a3
