Candidates': Svidler loses, favourites half a point behind leader

Round 4 at Candidates' was marked with two decisive games. In one of them Levon Aronian outplayed Peter Svidler and joined Vladimir Kramnik who drew Vishy Anand at 2nd place.  

Aronian once again managed to gain a win in Gruenfeld. However, he needed some special resources with "drastic" consequence: 


This position has been played in practise several times. Before the computer analyses became popular, the queen was moved on а6, and in this case, according to Svidler, Black is losing.
21...Qa3 formally isn't a novelty - it has been played several times but not on a high level. 
Svidler, "Here White has at least three continuations. I knew that after 
21.Bxf7+ Kxf7 23.Qc4+ e6 24.Ng5+ Ke8 25.Nxe6 Qe7 Black should not be worse." 
26.Nxg7+ Qxg7 27.Bc3

Svidler, "I saw that I could play 27...Nxd4 28.Qxd4 Qxd4 29.Bxd4 Rc4 30.Ba1 Rd8 31.f3. And it's clear that this endgame should objectively be possible to hold. But after spending 40 minutes I thought "No coward plays hockey. I still have an extra piece and I definitely shouldn't face a forced loss. Then I regreted this decision and not once..." 
27...Nd8 28.Qb3 
Svidler, "The position is really complex. Black has plenty of possibilities... But I decided that if I would let my both rooks play, I would be only half a move away from success. White would of course have a compensation for the piece, but..." 
Aronian, "I have a pawn for the piece. Usually it's not enough, but I saw that Peter spent a lot of time and that the position was uncomfortable to play for him. So, I was tyring to find the best move."
28...Rc7 29.Ba1 Rac8 30.d5 Qd7 31.Qb2 Qe7 Svidler said it was "the biggest mistake in the game", but objectively it is an exaggeration. The mistake was still ahead to make.  
32.Rbd1 Nf7 33.e5 Rc2 34.Qb5+ Qd7? Leads to a lost or almost lost endgame. Svidler had to try 34...Kf8 35.e6 Nd6.
35.Qxd7+ Kxd7 36.e6+ Kd6

37.exf7 The machine suggests even stronger and nicer move: 37.Bf6!! with a plan of moving pawn ahead. 37...R2c7 would be followed by 38.Bh4!.
Aronian, "Yeah, I had to be more attentive... But I was so happy to win the piece back that I didn't even consider other possibilities."
37...Rf8 38.Re6+ Kd7 39.Rf6 Re2 40.f4 Re7 41.Be5 Rexf7 42.Rd6+ Ke8? Perhaps the decisive mistake.
Svidler, "I was obliged to play 42...Ke7! No need in worrying about the pin after 43.Re1 because the bishop has no square to move. 43.Re1 Re7 44.Rc1
Svidler, "I am not sure if this position can be hold. I spent time on thinking didn't come up with anything worthy."
Black resigned on 57th move. 1-0

Svidler, "This was a very interesting game; important from a theoretical point of view. My main mistake was accepting the challenge..."
