1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.Nf3 dxc4 5.a4 c5? 

Morozevich likes to experiment in 1.d4 d5 openings but this combined with his next move, seems to me a highly dubious choice suited only for surprise. I really can't find a defense for black after the 7.e4 so i think that the question mark is justified. 
[5...Bf5; 5...Bg4; 5...Na6] 

6.d5 Bf5?! 
[6...e6 also leads to a better position for white] 

7.e3? 
[7.e4! is an excellent gambit.In fact i haven't been able to find anything resembling a defence for black : 

A) 7...Nxe4 8.Nxe4 Bxe4 9.Bxc4 With the terrible threat Bb5+ and Ne5. 9...Nd7 (9...e6? 10.Bb5+) 10.00 Bxf3 (10...g6 11.Ng5) 11.Qxf3 g6 12.Bg5! Making stronger the threat of d6. 12...Qb6 13.Rfe1 

and black will not make it to the 20th move.; 
B)
7...Bxe4 8.Bxc4 

B1) 8...g6? 9.Nxe4 Nxe4 10.Bb5+ Nd7 11.Ne5; 
B2)
8...Nbd7 9.00 

B2a) 9...Bxf3 10.Qxf3 g6 11.d6! is the most straightforward (11.Bf4) 11...exd6 12.Re1+ Be7 13.Bh6 and the game will soon end, for example: 13...Ne5 14.Rxe5 dxe5 15.Bb5+ Nd7 16.Rd1; 
B2b)
9...g6 10.Ng5 Bf5 11.d6 e6 12.Nb5 is another way of punishing black for the omission of b5.; 

B3) 8...a6 This wastes another tempo but the check from b5 is desicive in many variations. 9.00 

B3a) 9...Bxf3 10.Qxf3 g6 11.Bf4 Bg7 12.d6; 
B3b)
9...Nbd7 10.Re1 Bg6 11.Bf4 (11.a5) 11...Nb6 12.Ba2; 
B3c)
9...g6 10.Re1 (10.Ng5 Bf5 11.Qb3) 10...Bf5 (10...Bxf3 11.Qxf3 Bg7 12.d6) 11.Qb3 and black's situation is just horrible.(11.d6)

7...e6 
Now black has a comfortable position. 

8.Bxc4 exd5 9.Nxd5 Nc6N 
This simple move is improves from an older example in which black forced an ending that was slightly worse for him. 
[9...Be4?! 10.Nc3 Qxd1+ 11.Kxd1 Bg6 12.Nd5! Nxd5 13.Bxd5 Nc6 14.Bxc6+ bxc6 15.Ne5! Vulfson-Alatortsev,Kuibyshev 1942] 

10.Qb3 
The only move to worry black. [10.00 Be7! (10...Be4?! Black has no reason to force an endgame that is slightly worse for him. 11.Nc3 Qxd1 12.Rxd1 Bc2 13.Re1 Rd8 14.e4 Bd3 15.Bb5!; 10...Bd6!? is also good) and 11.Qb3?! fails after 11...00! 12.Qxb7? Nxd5 13.Qxc6 Nb4+ and the white queen gets trapped.] 

10...Qd7 11.Nxf6+?! 
[I think that 11.00! was much better so as to keep the centralised knight on d5 and to avoid opening the g-file for black's rook. 11...Ne4!? Consistent with black's general opening idea of controlling e4 and thus restrict Bc1. However the knight's position on e4 can be challenged. 
(
Another option is 11...Nxd5 12.Bxd5 Nb4; 11...Na5? is tactically suspect. After 12.Qb5! black has serious problems) 12.Rd1! (12.Nh4?! Be6 13.f3 Nd6) 12...Bd6 13.Ne1! planning f3-e4, with a very unclear and interesting position.] 

11...gxf6 12.Bd2 
[Now 12.00? loses the exchange after 12...Na5 13.Qc3 Nxc4 14.Qxc4 Bd3] 

12...Rg8!? 

Morozevich postpones castling for one move and activates his rook first. As it will become clear after the correct 13.000 he could just enter a comfortable ending with 13..Be6 so there is no need to hurry to castle. [After 12...000 white would have to play 13.000! with a complicated position(13.Bxf7? is bad because of 13...Ne5; while 13.00?! Bh3! is scaring to say the least...)

13.Bc3? 
White really pushes his luck. It was imperative to look after his king. [13.000! should have been preffered. Now black seems to experience some problems because he can't castle due to the weakness of f7 while Bc3 is coming. 
However after 13...Be6! black obtains excellent chances. The exchange of bishops relieves black from the pressure on f7 and the black queens will be posted beatifully at e6. Then white must either exchange queens repairing black's pawn structure or else the black queen will have future plans of landing on a2 or b3 making life difficult for the white king. An important factor in the position is the activity of the rook on g8 who can even participate on a queenside attack with ..Rg4. (13...Rxg2? 14.Nh4) 

A) 14.Bxe6 Qxe6 is also very ok for black. Now white must enter to a balanced ending because if he takes b7 with 15.Qxb7?! the initiative passes to black: 15...Rb8 16.Qa6 (16.Qc7 Rg4 17.Bc3 Rxa4) 16...Rb6! (16...Rxg2 is also possible but i like the immediate transfer of Rg8 to the queenside. White now faces the combined attack of black's pieces against his king. On the other hand the black king despite being in the centre isn't worrying at all.) 17.Qd3 Rg4! 

(17...Qa2 18.Bc3 Qa1+ 19.Kd2 Qxa4 20.Ke2) 

A1) 18.e4? Qa2! 19.Bc3 (19.Qa3 Qxa3 20.bxa3 c4+) 19...Bh6+! This is the shortcoming of 18.e4. 20.Nd2 Nb4! 21.Bxb4 (21.Qb1 Qb3 is also without hope.) 21...Rxb4 and white must lose his queen: 22.Qc3 Rc4; 
A2)
18.Bc3 18...Rxa4 and black has a strong attack 19.Qxh7? is suicidial 19...Nb4! (19...f5 is also possible) 20.Bxb4 Qc4+! The most forcing idea - found by Fritz 21.Bc3 (There is also no escape with 21.Kd2 Rd6+ 22.Ke1 Rxd1+ 23.Kxd1 Ra1+ 24.Kd2 Qxb4+; 21.Qc2 Ra1+ 22.Kd2 Rd6+) 21...Rxb2! 22.Qd3 (22.Kxb2 Ra2+) 22...Ra1+ 23.Kxb2 Qa2#; 

B) 14.Bc3 14...Bxc4 15.Qxc4 Qe6 16.Qxe6+ (16.Qb5 Rxg2 17.Qxb7 Rb8 18.Qc7 Rxf2) 16...fxe6 and the endgame must be evaluated 'equal'. However if I had to choose i would take black: after protecting f6 he can start pushing his queenside pawns ..b6,..a6,..b5 probably combined with ..Rg4. 17.Bxf6?! Rxg2 18.Bh4 Rg4!] 

13...000! 

Now white has no castling options and the hanging doubled pawns f6,f7 is a small consolation for this. 

14.Bxf7 
[14.Bxf6 Be7 15.Bxe7 Qxe7 seems hopeless for white as his king is stuck in the centre and all the black pieces are attacking.] 

14...Rxg2 15.Nh4 
Most probably Van Wely overlooked black's next move. 

15...Ne5! 16.Nxf5 Nd3+ 17.Kf1 Rxf2+ 18.Kg1 Kb8! 

These 'quiet' moves in the middle of an attack usually create an impression but this one is easy because white's position is completely demolished and his only threat was Be6. 

19.Qe6 
[19.e4 loses beatifully with 19...c4! 20.Qxc4 Bc5; 19.Be6 Qc6 20.Nh4 Bh6! and e3 cannot be protected] 

19...Rxf5 20.h4 Bd6 21.Rf1 Rg8+!
