It's the 1st time I've this line, now that the game is over I understand why, but I bet it just might start trending. :)

There are lots of scores of about 1.5 pawns starting around ply 40, but those scores are meaningless. It is just computers looking at the wood imbalances and even though no progress can be made, they say one side is considerably ahead.

The real peril started on white's 67th move and ended on black's 68th move. Carlsen put himself in a forced checkmate position, and four plies later, Caruna let him off the hook:

Drawn up to this point (Carlsen's 67th move)...
Carlsen moved Kg6, which put himself into a forced mate position, instead of Bc4 which draws:
[d]5k2/7K/5p2/3B1P1P/3n4/8/3b4/8 w - - move 67a; acd 92; acs 300; bm Bc4; am Kg6??; c3 "Kg6"; ce -142; pm Bc4; pv Bc4 Bg5 Bd3 Nc6 Bf1 Ne5 Bb5 Ke7 Kg7 Ng4 Be2 Nh6 Bd3 Kd6 Kh7 Ke5 Kg6 Bf4 Bb1 Ng4 Bd3 Be3 Bc2 Bg5 Bd3 Kf4 Be2 Nh6 Bd3 Kg4 Bc2 Kg3 Bd3 Kf2 Bb1 Ke3 Bc2 Kd4 Kh7 Ng4 Kg6 Kd5 Bd1 Nh6 Bc2 Kc6 Bd3 Kc5 Bc2 Kd5 Kg7 Ng4 Bd3 Kd4 Be2 Nh6 Kg6 Ke4 Bc4 Ke3 Be6 Kf3 Bb3 Kf4 Bc2 Ke3 Bb1 Ng4 Bc2 Ke2 Bb3 Bh6 Bc2 Kd2 Bb1 Bg5 Be4 Ke2 Bc2 Bh6 Bb1 Kd2 Be4 Bg5 Bd5 Ke3 Bb3 Ke4 Be6 Kd4 Bb3 Ke5 Be6 Ne3 Bc8 Nd5 h6 Ne7+ Kf7 Nxc8 h7 Nd6+ Kg6;

Caruna correctly punished with Bg5:
[d]5k2/8/5pK1/3B1P1P/3n4/8/3b4/8 b - - move 67b; acd 73; acs 300; bm Bg5; c3 "Bg5"; ce 32574; dm 97; pm Bg5; pv Bg5 Bc4 Bh4 Bd5 Ne2 Bf3 Ng1 Bg4 Kg8 Kh6 Bf2 Kg6 Bd4 Kh6 Be3+ Kg6 Bg5 h6 Kh8 h7 Bh4 Kh6 Bg3 Kg6 Be5 Kh6 Bf4+ Kh5 Kxh7 Kh4 Bd2 Bd1 Kh6 Kg4 Be1 Ba4 Ne2 Bc2 Bd2 Kh4 Nc3 Bb3 Ne4 Bc4 Nf2 Kg3 Nd1 Bb3 Nb2 Kf3 Kg5 Be6 Bc1 Ke2 Bf4 Ke1 Nd3+ Kf1 Nc5 Bc8 Ne4 Kg2 Ng3 Kf3 Nxf5 Ke2 Ng7 Kd3 f5 Kc4 Bc1 Be6 Nxe6 Kd5 f4 Ke4 f3 Ke5 f2 Ke4 f1=R Ke5;

Carlsen played the move which delayed the mate as long as possible:
[d]5k2/8/5pK1/3B1PbP/3n4/8/8/8 w - - move 68a; acd 73; acs 300; bm Bc4; c3 "Bc4"; ce -32579; dm -94; pm Bc4; pv Bc4 Bh4 Bd5 Ne2 Bf3 Ng1 Bg4 Kg8 Kh6 Bf2 Kg6 Bd4 Kh6 Be3+ Kg6 Bg5 h6 Kh8 h7 Bh4 Kh5 Bf2 Kg6 Bd4 Kh6 Be3+ Kh5 Kxh7 Kh4 Bf2+ Kh5 Be1 Bd1 Kg7 Ba4 Ne2 Bb5 Nc3 Bd3 Nd1 Bb1 Ne3 Be4 Kf7 Bb1 Ke7 Kg6 Bc3 Kg7 Kd6 Kf7 Ke5 Kg6 Nd5 Kh5 Bd4 Kg4 Ne3+ Kh5 Nxf5 Ba2 Ne7 Be6 Kxe6 Kh6 f5 Kh7 f4 Kh6 f3 Kg5 f2 Kf4;


Instead of playing Bh4 which wins, Caruna played Nf3, which draws:
[d]5k2/8/5pK1/5PbP/2Bn4/8/8/8 b - - move 68b; acd 75; acs 107; bm Bh4; am Nf3??; c3 "Nf3"; ce 32582; dm 93; pm Bh4; pv Bh4 Bd5 Ne2 Bf3 Ng1 Bg4 Kg8 Kh6 Bg3 Kg6 Be5 Kh6 Bf4+ Kg6 Bg5 h6 Kh8 h7 Bh4 Kh5 Be1 Kg6 Bc3 Kh6 Bd2+ Kh5 Kxh7 Kh4 Be1+ Kh5 Kg7 Bd1 Kf7 Ba4 Ke7 Bb5 Nf3 Kg4 Nd4 Bc4 Bd2 Bd5 Kd6 Bb7 Ke5 Bc8 Nc6 Be6 Ne7 Bd7 Bc1 Be6 Nd5 Kf3 Ne3 Bf7 Nxf5 Kg4 Nh6+ Kg3 f5 Kg2 Nxf7 Kf2 f4 Kf3 Nh8 Kg2 f3+ Kf2 Bf4 Kg1 f2+ Kf1;

Game is drawn from this point forward.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.

Thanks for this W Ch game. Seems there's a forced Mate in 40 after move 69 of black.

Missed chance by Caruana but very difficult mating line for mere mortals, as the
line is counter-intuitive with 70...Ng1!! in mating line, gettingtrapped by B of white.

I told my wife that a husband is like a fine wine; he gets better with age. The next day, she locked me in the cellar.

Instead of playing Bh4 which wins, Caruna played Nf3, which draws:
[d]5k2/8/5pK1/5PbP/2Bn4/8/8/8 b - - move 68b; acd 75; acs 107; bm Bh4; am Nf3??; c3 "Nf3"; ce 32582; dm 93; pm Bh4; pv Bh4 Bd5 Ne2 Bf3 Ng1 Bg4 Kg8 Kh6 Bg3 Kg6 Be5 Kh6 Bf4+ Kg6 Bg5 h6 Kh8 h7 Bh4 Kh5 Be1 Kg6 Bc3 Kh6 Bd2+ Kh5 Kxh7 Kh4 Be1+ Kh5 Kg7 Bd1 Kf7 Ba4 Ke7 Bb5 Nf3 Kg4 Nd4 Bc4 Bd2 Bd5 Kd6 Bb7 Ke5 Bc8 Nc6 Be6 Ne7 Bd7 Bc1 Be6 Nd5 Kf3 Ne3 Bf7 Nxf5 Kg4 Nh6+ Kg3 f5 Kg2 Nxf7 Kf2 f4 Kf3 Nh8 Kg2 f3+ Kf2 Bf4 Kg1 f2+ Kf1;
Note there's no need of EGTB to find 68...Bh4. This move simply wins a pawn after some zugzwangs.
