  Honza Cervenka: <sicilianhugefun: Are you a grandmaster Honza Cervenka? It appears thay you are a top class or first rate GM> Unfortunately not. I am only an amateur of solid club level who used to play correspondence chess back in 1990s and got a Candidate of Master title then. But I am good enough to be able to win a position, which Aronian had after 40 moves in this game, even against Vallejo-Pons. Well, to reach that position, it would be a bit different matter....:-D
Sep-27-11  Ulhumbrus: The move 5...b4 leads to a backward pawn on c6.

According to the chessbase website the move 7...Qxd4 is an innovation which does not turn out well.

According to the chessbase website the move 26 Nd4 is not the best and 26 Ng5 is better. The move 26 Ng5 prevents the reply 26...Be4 instead of 26 ...Ne4 as played, a move which the chessbase website calls a mistake.

Sep-27-11  sevenseaman: <Pons> cant stop pawns.
Sep-27-11  Ulhumbrus: After 13...Bxf6 14 Rfd1 the threat of 15 e5 followed by 16 Ne4 and 17 Nd6 seems so strong that inatead of 13...Bxf6, 13...gxf6 seems necessary. On 13...gxf6 14 Rfd1 Bxc4 15 Nxc4 Qc7 Black has the d6 square covered twice, so White can't play 16 Nd6+ and deprive Black of the right to castle whereas after 13...Bxf6 14 Rfd1 Bxc4 15 Nxc4 Qc7 White has the option of 16 Nd6+ depriving Black of the right to castle.

That position was pretty late in the game.

Sep-27-11  Ulhumbrus: After 19...Qc7 one way for Black to lose is 20 Nxf7! Kxf7 21 Qf5+ Kg8 22 Qxe6+ Kh8 23 Rxd7
Sep-27-11  sicilianhugefun: That's great Honza.. and tnx by the way... what chess book can you recommend for reading?

No, you are not the only one. He really makes magic happen on the board. This game is incredible.

Sep-28-11  lazyknight: <tpstar: Picture caption: See No Evil, Hear No Evil>

and Speak No Evil! you missed the third guy in the pix.

Oct-03-11  Jambow: <KingHunt><Am I the only one completely wowed by Aronian's play in this game? I've gone through the game four times now and can still barely comprehend half his moves.>

Surprised actually Aronians moves were not hard to understand even at my level? Played over it twice to be sure. Not trying to be insulting maybe its just a style thing?

Feb-05-22  Brenin: After a lot of unsuccessful thought I saw 27 Qh6 Nxd6 28 Bxg6 (threat 29 Qh7 mate) fxg6 30 Qxg6+ Kh8 31 Qh6+ Kg8 32 Nxe6 (threat 33 Qg7 mate). I was afraid that Black might have an adequte defence, e.g. 32 ... Nf5, giving up the exchange, or even 32 ... Qxe6 33 Qxe6+ Nf7, but hoped that after Qg6+ and Qxh5+ White's pawns would crash through.

Feb-05-22  Captain Hindsight: Even though there were many forced moves, today you should have seen at least 10 moves in advance (up to 37.Qxf5> and then also correctly assessed this unbalanced position.

  parch: Did not think 27.B:e4 was todays puzzle,

27.Qh6 looks good, Δ 28.♗:g6

Thought 27...Qe8 would be a stronger defence 28.N:e6 fe6 29.Rd7 Rf7 30.Q:g6+ Kf8 31.R:f7+ Q:f7 32.B:e4 Q:g6 33.B:g6

Feb-05-22  Brenin: According to SF (<mel gibson>'s and the local version) we all, including those kibitzers from 2011, overlooked 28 exd6 as marginally better than 27 Bxg6. It is interesting how we humans rush in with a second sacrifice, while the engines patiently bring in reinforcements.

  scormus: Great gane by Aronian.

I called it the same as <brenin>. Reject 27 Nxe6 in favour of Qh6, then the sac sequence, threaten #, regain material, conclude W should win with the extra pawns. The moves all seemed so natural, I thought that was it.

Then I found SF didn't quite see it the same way. 27 Bxe4 picked at first before switching to Qh6 after going deeper. Then 27 .... Qc5 instead of .... Nxd6.
At least it followed the text after that .....

  scormus: ... ah-ha. Now I've let SF run a bit longer, 28 exd6 as well! Oddly, I considered but rejected that as I thought Bxg6 was stronger. I'd better quit SF before it finds another new twist!

  agb2002: Black threatens Nxd6.

The white queen can go to h6 at once and hit g6 and Black's second rank. This suggests 27.Nxe6:

A) 27... fxe6 28.Qh6

A.1) 28... Nxd6 29.Qxg6+ Kh8 30.Qh7#.

A.2) 28... Qe8 29.Rd7 Rf7 30.Qxg6+ Kf8 31.Qh6+ Kg8 32.Rxb7 Rxb7 33.Bxe4

A.2.a) 33... Re7 (to protect e6) 34.Bxa8 Qxa8 35.Qxh5 wins three pawns.

A.2.b) 33... Rxb2 34.Bh7+ followed by 35.Bg6+ wins decisive material.

A.2.c) 33... Rg7 (aiming at g2) 34.Bxa8 Qxa8 (threatens Qxg2#) 35.Qxe6+ and 36.Qd5 as in A.2.a.

A.3) 28... Rf7 29.R6d4 (29.Qxg6+ Rg7 30.Rd8+ Qxd8 31.Rxd8+ Rxd8 32.Qxe6+ Kh8 33.Bxe4 Bxe4 34.Qxc4 Rd1+ 35.Kh2 Rxg2+ 36.Kh3 Rh1#) 29... Nc5 30.Bxg6 Rg7 31.Qxh5 followed by Rg4 is probably OK for White.

B) 27... Nxd6 28.Nxf8

B.1) 28... Nf5 29.Nd7 wins a pawn with the better position.

B.2) 28... Qxf8 29.exd6 as in B.1.

B.3) 28... Kxf8 29.Qh6+ resumes the attack with an extra pawn.

Feb-05-22  landshark: The position after White's move 33 would be a decent Wednesday puzzle.

That's where I stopped just looking at the game <forget about solving this from the starting position> and allowed myself to consider, "what would I play here?" I actually got it right from that point - take the R on f8 threatening Qh7#, and after Black recaptures with his Q, drop the R down to e7 with lots of juicy threats. I even saw the theme of trading off Q's as quickly as possible and try to use the 4 connected passers vs Black's B as the way to press for the win...

But never, ever, <ever> would I have been able to steer the game towards that position from the puzzle position with White to play at move 27 -
