Apr-01-18  BOSTER: Carlsen plays very fast.

Case in point: Poor Hou!

  An Englishman: Good Morning: 59.h5! kept the Black King out of g6 and clinched an easy win, no need to get fancy with my fantasy sacrifice.
Apr-01-18  Octavia: well done, Magnus!
Apr-01-18  Ulhumbrus: Suppose that if instead of 54...Nd5+ You Hifan tries 54...Ne5 and Carlsen tries the invasion 55 Ra1 as in the game. Then on 55...Nxf3 56 Kxf3 one difference is that Black's d pawn is not isolated and on 56...Re5 57 Kf4 Rc5 White may still win but possibly with greater difficulty than in the game.

  Richard Taylor: Here's some computer analysis that proves Yifan Hou should have won:

34...Nf6 35. Nd2 h4 36. c4 bxc4 37. bxc4 Re7 38. Rd6 Rd7 39. e5 Rxd6 40. exd6 Kf8 41. Kg2 c5 42. Kh3 Ne8 43. Ne4 f5 44. Nxc5 Nxd6 45. Kxh4 Nbxc4 46. Kg5 Kg7 47. h4 Ne3 48. Bb1 Nf7#

How could she miss that?

  Richard Taylor: Joking aside the position would have been about =

34. Nf1 Nf6 35. Nd2 h4 36. c4 bxc4 37. bxc4 Re7 38. Rd6 Rd7 39. e5 Rxd6 40. exd6 Kf8 41. Kg2 c5 42. Kh3 Ne8 43. Ne4 f5 44. Nxc5 Nxd6 45. Kxh4 Nbxc4 46. Kg5 Kg7 47. h4 Ne3 48. Bb3 which stops the mate.

Of course the long analysis could well be wrong but it looks as though 34. ... Nf6 was better.

Carlsen is addicted to and an expert in having a "slight advantage" but could he have made anything from the game?

Apr-01-18  Gregor Samsa Mendel: <Richard Taylor>--Carlsen is well known for his ability to squeeze the blood of victory from the turnip of a quiet endgame. As his encounter with Caruana yesterday showed, this doesn't always work at the very highest levels.

  alexmagnus: But he was winning vs Caruana too, just that the win was too complex even for him.
Apr-01-18  Marmot PFL: <How could she miss that?

Carlsen plays very quickly which puts extra pressure on his opponents. When Hou blundered she was down to 8 minutes or so while Carlsen had nearly an hour left.

Apr-01-18  beenthere240: 21. Qc1 was a master stroke, encouraging 21.... BxN and giving MC a doubled f pawn, which he used to great advantage, striking twice on f4.
Apr-01-18  Marmot PFL: Actually it's much to harsh to call 34...Rf6 a blunder as it's still very hard for white to win this. In fact she might have drawn with 38...Rg5 as explained in this video (about 8:50)

Well it shows that humans make errors as even Capablanca's ending's were not always computer perfect (I analyzed some). Nevertheless one can learn or enjoy the games of these old and newer masters. I think Caruana has a good chance in the battle in November.

Endgames require accurate calculation and here it didn't happen regardless of his reputation. All of those GMs are au fait in the endgames to a greater or lesser extent.

But all can make The Blunder or The Error. And that is what makes practical chess interesting...Perhaps Carlsen is in decline, it is always a fear he and his fans might have...

Hou is part of the #MeToo club, along with everyone else in the world of chess. It’s a big group

Aug-21-23  Whitehat1963: The strongest player refuses to participate in championship matches, and the strongest woman player refuses to play in women�s championships. A sad state of affairs for chess.
