Kibitzer's Corner
Jul-27-10  Marmot PFL: A good test is to set your computer to make black's 35th move, and see how long it takes to realize that Qxh4 is a mistake. Mine (slow) is on about 4 minutes and counting, So maybe it never will.
Jul-27-10  TheChessGuy: 45.Kc4 takes the diagonal opposition. Black still has a tempo move however, namely 45...f6. White is undeterred and answers with a hard punch of reality-46.d5+! Black can accept the sacrifice (with check!) and is still completely lost. 46...cxd5+ 47.Kd4 f5 (best, but offers no chances) 48.c6 Kd6 49.c7 Kxc7 50.Kxd5 Kb6 51.Kd6! and White gets to the kingside faster than Black can take the a-pawn. He'd win by snapping off the h-pawn and queening his own h-pawn (this covers Black's promotion square on a1). Great endgame play by Anish!
Jul-27-10  Shams: <TCG> What is black's 44th?
Jul-27-10  TheChessGuy: 44...Ke6 Thanks for pointing out the skipped move.
Jul-27-10  dotsamoht: This is truly a beautiful ending by Giri. It looks so simple and even... but is in fact neither.

Many of the kibitzers thought the evaluation 1-0 at the end was a transmission error. It took awhile to realize that Giri had pulled off a masterpiece.

37 Kf1 reminds me of Korchnoi. "These are the ABCs of chess!" he once told Joel Benjamin in a similar ending.

Jul-27-10  freakclub: Where did Wesley go wrong here? I think 19...Qxf2 would have offered more favorable chances for black. E.g. 20.Bxf6 gxf6 21 cxd5 Qxd4, etc.
Jul-27-10  zanshin: <Marmot PFL: A good test is to set your computer to make black's 35th move, and see how long it takes to realize that Qxh4 is a mistake.>

<Marmot> Rybka 4 finds this quite readily: Wesley So

There's a typo. I meant move 35 for Black (24 was ply depth).

Jul-27-10  freakclub: Thanks for the analysis Zanshin. It turns out that Giri was lucky again this time, just like in Corus against Wesley. Some guys have all the luck.
Jul-27-10  Marmot PFL: <zanshin> I have an older version, and it could not solve it. Time to upgrade i guess,
Jul-27-10  licuan: wesley does not study endgames yet? . . . .
Jul-28-10  zanshin: <Marmot PFL: <zanshin> I have an older version, and it could not solve it. Time to upgrade i guess>

<Marmot PFL> Try one of the new free engines like Fire 1.3 or Stockfish 1.8. I'm pretty sure they will do well. If you need the links, they are in my forum bio.

<freakclub: Thanks for the analysis Zanshin. It turns out that Giri was lucky again this time, just like in Corus against Wesley. Some guys have all the luck.>

<freakclub> I don't think it's all luck! Giri pulled out wins in a losing position (Corus) and a drawn one (Biel). In both cases, he had a plan: to cause Wesley to fall into a swindle and to commit a positional blunder. Painful lessons, but Wes needs them to learn.

Jul-28-10  zanshin: I think the final position is interesting for engine analysis (move 44 for Black). At low ply levels, Rybka 4 assesses the position as equal because material is equal. At successive plies, the evaluation increases for White because Black cannot prevent the pawns from Queening.

  An Englishman: Good Evening: Rather an impressive endgame win for Giri.
Jul-29-10  GalileoPiccolino: Always a lucky win for AG against WS.
When WS finally wins a game sometime in the future, it will not be attributed to LUCK.
Jul-29-10  Raspje: Saying this was a lucky win indicates a certain level of ignorance. Wesley So is a very talented young player but he played this endgame way too fast. Giri is well known for his great endgame technique so So should have gone in thinking mode. Maybe So needs a coach, as far as I know he hasn't got one.
Jul-31-10  Don Cossacks: People who say that this is another lucky win is truly in denial...

  SugarDom: Exactly Blunderdome. I had to delete my celebratory kibitz on cg.com after a few seconds...
Mar-08-13  tolitz4x: i think Giri is wesley So's jinx!!! most especiaaly in corus B when Wes is way ahead in pieces... i think and everyone here will agree that in that game Giri won by luck... Wes was over confident and played blitz. And to his surprise Giri was able to play a force move. But in the near future the most awaited rematch will be exciting because of their archrivalry.
Jan-22-15  TangoJoseph: Does 37 ...f3 by Black hold a draw ?
Aug-24-15  epistle: 1 - 0 again in another 44 moves. Prove me wrong wesley and make it 45.
