The Reti has not been a popular choice in battles among top players. Black too easily finds equality. However, today's game had imbalances. Both sides had strengths. Carlsen thrives in equal but unbalanced positions.
At a critical point in the game, Anand rejected a line that many commentators believe gave him strong winning chances.
I think I made a couple of misjudgements in the middlegame.
Magnus Carlsen, Press Conference
Whenever I go on any pawn hunting expedition, he always generates enough counterplay.

10...Nd4
Anand's move appears to be a novelty. My engines see equality after 10...Be6, but a slight edge for White after Anand's move. Such engine evaluations are not particularly trustworthy. Engines have improved vastly in positional evaluation over the past few years, but top Grandmasters remain stronger at this element of the game.
More important than what engines think is how well Anand and Carlsen understand such positions. Today's game reveals that both found the game difficult, but they were able to maintain relative equilibrium. It was a satisfying draw.

The game has reached an interesting position. Black's queenside pawns appear strong, but White has active play and possible threats on the kingside and in the center. The threat of Qd6 to swap queens and bishops might be a prelude to a maneuver to set the knight on c4 as a blockade.

Black to move
29...Bd4
Does 29...Bxb2 offer Black winning chances? Anand was asked about it in the post-game press conference. Andrew Martin thought it offered Black good prospects. His YouTube video on today's game looks at several lines that end with a queen and pawn ending where Black has an additional passed pawn.
Anand was asked about 29...Bxb2 by Anastasia Karlovich, host of the press conference. He admits that he "might have been mistaken," but he thought White had "enough play for the pawn." I recall that Carlsen had about ten minutes, and Anand perhaps twelve at this point. With more time on the clock, there would have been an opportunity to calculate more deeply.
After 29...Bxb2!? 30.Rae1 Rb6, 31.Bd5 looks sharper than 31.Bh3. In either case, play would continue with 31...Bd4 (White is clearly better after 31...Rxd5 32.Qxd5 Bxd5 33.Rxe7).

Daniel King noted that Anand would have needed to find this move before playing 29...Bxb2. Andrew Martin highlighted the importance of Black's next move.
35.Rxd6 Qxd6 and Black seems better. Was this complex sequence a real chance for a win?
Anand chose to keep the game under control.

33...Qb4
Anand might have tried 33...Rf8. This was the second point where commentators have suggested that Anand might have found some winning chances. Anand was asked about this line in the press conference. He said that he did not see any clear advantage that would come from winning the f-pawn.
In the three videos that I watched, only King suggested 34.Kh2 to step out of the pin.

However, the line 33...Rf8 34.Kh2 seems less promising. Indeed, Black's king may prove less secure than White's.

37...Rd8
Even here, Anand had to defend his choice, as journalists thought this rook could go to f8 and the bishop to d4 to exploit a weakness on f2.
38.Rxd8 Bxd8 39.Bd3 Qd4 40.Bxb5 Qf6
It is alleged that Anand offered a draw here, and that Carlsen refused.

After three days of complaining about two short draws to begin this match, the players have given chess fans a game that we can argue about for the next decade.
34...Rdd6! is indeed best, but things are far from clear after 35.Kf1. I have not been able to find a convincing way for Black to get a real advantage.
