Gilmoy: Full-game impressions:
1. <9..e6 10..Nbd7> Slav-ish, and Carlsen has already solved his bad-LSB problem.
2. <12.Rac1 Rc8> Shadowboxing! Mutual respect? They both fear the other guy's TN if they make any obvious center capture :)
3. <13.Be1 17.Bf1> GM Bishop thing! (A Rustemov vs D Skorchenko, 2008) Both still probing around for an unexpected breakout. Meanwhile, White cleverly exploits the little space he has for respectable waiting moves. Notice how Carlsen's Knights don't have the same luxury -- N moves are more commital. An unexpected benefit of the <bishop pair> -- they're better at pussyfooting!
4. <17..Bf8> Carlsen's grumble-I'm-in-dang-zugzwang-already Bishop thing of his own ...
<18.Qb1!!> ... is excellently trumped by Chucky's Queen thing!! <He who undevelops more pieces, wins!! :-O>
5. <19.g3 20.Bg2 21.Ne2> Now Ivanchuk's got some annoying hidden-pressure on the b7-c6-d5 pawn chain, whereas his own Q-side pawns have adroitly dodged Carlsen's Grun bishop. Who could blame Carlsen for arranging his pawns like that? Our opening analysis usually does not cover the fianchetto on move 20. Quoth erstwhile correspondent NN: <I didn't even know move numbers went that high -->
6. <25..dxc4 26.bxc4> Chucky's Qb1 yawns and stretches --
7. <27.c5!> I guess to freeze the b7-pawn? But it fits this game's uber-theme of making waiting moves and giving the other guy more rope than he's giving you ...
8. <27..Rcd8?!> Carlsen either cracks (unlikely), or outsmarts himself (possible), thinking that he's offering a "poisoned b7" for tempi + clearance to heavy-double on 2 and hunt sideways. Normally a deadly idea -- but Chucky peers through the ply-fog, and sees that his "deflected" Qb7 has back-rank mate threats of his own! Carlsen surely considered N(either)d7, and judged it blah -- it's probably drawish precisely because it holds everything. And he really wants his omelette ...
Objectively, Carlsen just unzipped his own protection-chain. Re8 is-chained-to Ne5, Qc7 is-chained-to b7, so who's protecting Rd8? Ergo, he's sacking for activity -- in fact, he's (will-be-)offering N+PP!! See above about avoiding the obvious center captures -- I think this qualifies ...
9. <32..Qb2> A critical position -- hanging Ne4 with counterthreat to Rc1 and Qb7. Now <33.Qxc2 Bxc2 34.Rf1 Nxc5> leaves White with terrible problems holding his a-pawn, so Black has compensation, and may even be winning. <34.Rc4? Rd1+ 35.Kh2 (Bf1?? Nd2 
) Nxf2> and White's N is-chained-to e5 (else Be5#).
10. <33.Ne7+ Kf8> I think Carlsen saw annoying complications in <33..Kh7 34.Qxe4! Qxc1+ 35.Kh2> and White has g5 with mate threats at h6. Nonetheless, Black probably escapes that line with a draw, e.g. <35..Bf8!> to settle the mate threat ASAP. Letting White trade Ns with check dissolved pressure, and Black is simply down PP. <35..Kf8 36.Qa8+ Ke7 37.Qb7+> forces a Q trade when Black's back-rank threat is gone -- now White can safely play <Rc4> and push the c-monster.
