Sep-04-12  rapidcitychess: Ala Capablanca, he makes Aronian look like a child. Simplistic ideals that were underestimated, and destruction is the end result.
Sep-04-12  visayanbraindoctor: <rapidcitychess: Ala Capablanca>

I thought this game has the same theme as Capablanca vs Lilienthal, 1936

Best game of the Olympiad so far.

<Karpova: Fontaine: When I sacrificed I already saw the situation with Qb6>

That's downright astonishing! 26. Qb6 is the type of quiet move that is incredibly hard to find because most players do not even consider it in their list of candidate moves in their calculations. (Apparently, even Houdini did not consider it as well.)

Sep-05-12  paavoh: @Everett <You are kidding us, right?> Of course not. I did not mean to imply that Nyback-Carlsen was the only prior example. You are right to point out that such or similar sacs can be found earlier. I was just making a note of a recent, rather notable game that I recalled.
Sep-05-12  Eyal: <(Apparently, even Houdini did not consider it (26.Qb6) as well.)>

An engine automatically considers all the legal moves in a position... and with enough ply-depth Houdini certainly comes to evaluate Qb6 as the best move. But in the position after 21...Rc7 it does take quite a bit of ply-depth (about 20-21 on my engine) to appreciate how strong is 22.Na5, followed some moves later by Qb6 – more than the ply-depth that was provided by the live "computer-kibitzing" on the official site; which is why it wasn’t showing 22.Na5 as top recommendation before Kramnik played the move and people started saying that "the computer didn’t see it". At any rate, the ply-depth needed for the engine to appreciate the strength of 22.Na5 and then 26.Qb6 does indicate the depth of calculation required to make sure this combination works.

Sep-05-12  rapidcitychess: <visayanbraindocter>

Funny, I haven't even seen that game. I will make an effort to store it in my memory banks.

Also, I will just say: Having some one who makes as intelligent posts as <visayan> agree with me makes me feel accomplished. ^^

Sep-05-12  Ulhumbrus: 26 Qb6!! pins the knight on c6 by attacking indirectly for a third time the rook on c7
Sep-05-12  visayanbraindoctor: <rapidcitychess> De nada. I read your comments myself whenever I come across them. (",)
Sep-06-12  jefballard: Future GOTD
Sep-10-12  lemaire90: Crazy game by Kramnik !! Every move is perfect. No doubt Russia was disappointing with the silver.

  Honza Cervenka: Let Kramnik to create a passed Pawn and you can just resign. This game reminds me Kramnik vs Aronian, 2006, Kramnik vs Aronian, 2007 or Kramnik vs Aronian, 2010
Sep-11-12  SChesshevsky: It looks like 7...g6 might not be best in the exch Slav.

The loss of the ...g6 and Bg7 tempo's might have helped White double those rooks on the c-file and the Black B on g7 doesn't look that well placed anyway.

And further tempo's with ...f6 and ...Bf8...Bd6 strangely looked to allow White's Nf3 to travel a long way without any real counterplay.

  Phony Benoni: I can do without these puns based on Twitter-Speak. They're all Latin to me.
Jun-16-15  offramp: <jefballard: Future GOTD>, you are correct, sir!
Jun-16-15  morfishine: Erroronian must've felt like a turkey after Kramnik gobbled up those Q-side pawns

  al wazir: OK, I'll show my tactical weakness. After 26...Rb8 27. Qxb8+ (as suggested by <Eyal>) 27...Nxb8 28. Rxc7 Qb5, what's next? I don't see anything terrible happening to black. The continuation might be 29. Re7 Nc6 30. Rxe6 Nxb4 31. axb4 Qxb4 32. Rc7 Qb8 33. Ree7.

Black is ahead in material, but the outcome is unclear. White certainly isn't winning now.

Jun-16-15  morfishine: <al wazir> Perhaps 27.Qc5 to hold the tension

  al wazir: <morfishine: Perhaps 27.Qc5 to hold the tension>. Then 27...Rbc8. If 28. b5, then 28...Nxd4. If 28. Qb6, then 29...Rb8, repeating the position.
Jun-16-15  drleper: <(Sep-04-12) visayanbraindoctor: 26. Qb6 is the type of quiet move that is incredibly hard to find because most players do not even consider it in their list of candidate moves in their calculations. (Apparently, even Houdini did not consider it as well.)>

Engines must be progressing along, Stockfish 6 wants to play 16.Qb6 right away.

<al wazir> 29.R1c5 is a nice move, and Re7 after that stops Nc6 (e.g. 29...Qb6 Re7 and Nc6 doesn't work). The rooks are too strong, white is going to win the piece back and have the two rooks and maybe a passed pawn. Even in the line you gave (ending in 33.Ree7) black doesn't have much prospect. The black king is stuck, the rooks threaten mate (so the queen has to watch that), white's pawns and king are totally safe too. Then there's some check, check, skewer ideas for white (giving up a rook to skewer the king and queen. No good.

  kevin86: The pawn will queen, leaving black a queen down for a lone, isolated Cavalier.

  al wazir: OK, I see it now. In the line I gave, where black stations his ♕ on the eighth rank to guard against a back-rank mate, it eventually gets skewered:

<26...Rb8 27. Qxb8+ Nxb8 28. Rxc7 Qb5 29. Re7 Nc6 30. Rxe6 Nxb4 31. axb4 Qxb4 32. Rc7 Qb8 33. Ree7> Qb1+ 34. Kh2 Qb8 35. g3 h5 36. Rg7+ Kh8 37. Rh7+ Kg8 38. Rcg7+ Kf8 39. Rh8+.

Jun-16-15  RandomVisitor: After 19.Nd2, the suggested improvement 19...Na7 requires deep and precise play to equalize, at least in these lines:

  FSR: Wow. I would never have taken 22.Nb7 seriously, let alone dared to play it - particularly against the likes of Aronian.
