Jun-27-11  Cushion: This is actually an amazing game produced by computers. I'm sure HIARCS didn't calculated to winning the piece back.
Jun-27-11  computer chess guy: Up to 14. Bh2 this has been played in a couple of human games, for example Szabo-Kislik, Budapest FS GM 2009 (not in db). But those continued .. dxe4. 14. .. ♕a5 may be a Hiarcs book novelty (Hiarcs has a very good book) but computers also like it because in exchange for the piece, White gets open lines and prevents Black from castling. Rybka 3 evaluates the position as equal.

  al wazir: I would never have guessed this was a computer game.

I would have played 33. Nc5. Why didn't HIARCS play it?

Jul-06-11  consul: I'm wondering whether White will win the piece back if Black plays 23 .. Kc8
Jul-06-11  Zan: <al wazir: I would have played 33. Nc5. Why didn't HIARCS play it?>

Not sure what the computer was thinking, but to me, after 33.Nc5 a5, it's much more difficult to bring the white knight into attack against the f and g pawns, as you either have to move Nd3...Ne5 to threaten the F pawn, which black easily protects, or from e4, the knight doesn't really have anywhere to go.

There's already a pawn advantage for white on the a, b and c files, so the knight shouldn't be necessary to get through there - stopping black's counterattack on f and g is important.

  Check It Out: 13.Bf4


13...e5 14.Bh2

Okay, so the black e-pawn is pinned to the Queen, but then the queen threatens destruction with:


Right. Now what? Moves 14 - 24 are mind-blowing.


How do you even think of that? An example of really excellent d-file pressure. For all that chess computers are hated on, they reinforce the notion that chess is still a beautiful game even with all their damn logic.


Clog up the d-file and apply pressure to a2.


Giving up the f pawn would not be my first choice.


Cool; sac the knight, munch the a-pawn, and kill with the three connected passed pawns.


This game had three stages:

Stage 1: Opening book: every move seems to advance the attack/counter attack theme of the Sicilian Defense: Scheveningen Variation. English Attack.

Stage 2: White sacs a piece for open lines and a vulnerable black king. Apparently Anand has not pulled this one off - yet.

Stage 3: Recover the piece, get rid of the rooks, and simplify to a won end game.


<al wazir> I suspect that HIARCS decided aiming for g7 was more critical than aiming for a6. It already knew that it's king was going to mop those queen-side puppies up.


<Cushion> Yes, it would be rather disturbing if HIARCS had foreseen everything to the end and played 13.Bf4 with a yawn.

Who would have thought it? Computers playing sacrifices in return for positional gains that they will not cash in until many many moves later.

Opening book or over the board brilliance?

Either way it seems that the human race is doomed. Doomed, doomed, I tell you. Never trust an Austrian bodybuilder on a Harley. Unless it's the sequel when you should place all your trust in an Austrian on a Harley. Or something like that.

And what a comment it was.

Sad, really.

  HeMateMe: Doesn't white also win easily with 41. Nxf7? the black Knight will have to babysit the passed pawn on the g file and white wins easily (even more easily than in the actual game) on the queenside?
Jul-06-11  moodini: <HeMateMe: Doesn't white also win easily with 41. Nxf7> It may well be that 41. Nxf7 wins faster but this might be one of those cases where the computer prefers to go into a tablebase win rather than what appears to be better to a human. Its choice of moves results in there being 6 pieces left on the board pretty quickly, whereas Nxf7 can result in there being more pieces on the board for quite a few moves.
Jul-06-11  CapablancaFan122: Judging from the pun, I thought this was one of those games where the computer stupidly sacrifices its pieces or doing something that a human wouldn't do. And I believed my thoughts were confirmed with <13. Bf4>. Who would have known HIARCS actually saw an advantage in that position?

  kevin86: Three passed pawns vs a knight-even I would have resigned earlier.
Jul-06-11  scormus: <newzild: An utterly brilliant game! Sad, really.>

I remember a Sci Fi film and someone asked "what would it mean if robots did that?" Answer given "It would mean the end of life as we know it"

<Once> "what would it mean if computers play sacrifices in return for positional gains that they will not cash in until many many moves later?" Answer "It would mean the end ...."

Jul-06-11  SirChrislov: in final position looks like the black king is about to get run over by a bull. and the game was played in pamplona. lo

sorry, some days I have a childish sense of humor.

Jul-06-11  WhiteRook48: nice game
