Oct-20-09  firebyrd: "Hou dunnit" ?

Wouldn't punning 'Hou' with 'How' be closer both in writing and pronounciation. "Hou impressive...", "Hou did she do it", etc. etc.

Oct-20-09  sofouuk: <firebyrd> afaik 'Hou' is pronounced more like 'hoe' than 'how' (or indeed 'who') ... so 'Ho, ho, Hou!', perhaps?

  lostemperor: This is impressive even if Carlsen had played it recently and he is 18! From the same Corus 2008 I took her photo had put on Hou's bio page for some time:)
Oct-20-09  JohnBoy: What is particularly impressive to me is the sequence from 21...e5 to 28...Bxh4 where black goes from giving up and X to being up an X. Now I have to go back and rethink white's options in this opening. Black's defensive resources are fare more substantial than a first glance suggests.
Oct-20-09  JohnBoy: Amusing is that white can't play 35.Qc4+ trying to pick up the a pawn. Black responds with 35...Qf7 and white must stop ...Rd1+.
Oct-20-09  ounos: A very special game. But can such wild attack be sound? Very impressive.

<JohnBoy> good catch!

  kevin86: After the final exchange of pieces,white's king is one step too slow to catch the h-pawn
Oct-20-09  drpoundsign: Smeets shoulda resigned sooner. He was doomed
Oct-20-09  weisyschwarz: Fiery persistence by Yifan Hou!!
Oct-20-09  sfm: Nice defense put up by white. Nice ending.
Oct-20-09  WhiteRook48: interesting skewer at the end
Premium Chessgames Member
  Jimfromprovidence: 49...Qe4 looks very good, perhaps even better than the text ...h4.

The threat is either 50...Qb1 or Rb1.

For example, if 50 Ka3, then the threat is 50...Rb1, seeing 51...Qa8+.

Now, after 50 Ka3 Rb1 51 Qf7 Qa8+ 52 Ba7, then 52....Qxa7+ wins the bishop as the queen will be skewered after white's next move.

  SuperPatzer77: What happens if it is 58. Kf5 instead of 58. Be5?

Let's show you about this below:

58. Kf5 g6+! (real killer by forcing White into the mating traps) below:

59. Kg4 Qg3#

59. Kf6 Qe7#

59. Kg5 Qg3+, 60. Kf6 Qf4+, 61. Qf5 (forced) Qxf5#

So, that's why 58. Be5 is forced (only move).

Black forces simplification by 58...Rxe5+! leaving White no choices.

Brilliant tactics by the teenage Yifan Hou!!!
