  whiteshark: I Justwanto play chess all day.
Oct-15-09  Samagonka: Now that's what I call a good game! Very good moves by both players, cut and clear attack by whitE - boldly sealing the victory with one of the most beautiful rook sacs I've ever seen.
Oct-15-09  viking978: Nice attack!

Oct-15-09  RandomVisitor: Interesting would be 19.Rd1, 23.Bh4 and 26.f5 as possible improvements.
Oct-15-09  mertangili: 32...gxf5 puzzled me for a while as i couldn't figure out the proper continuation (i couldn't make the immediate capture of the bishop work). But then i see:

32...gxf5 33.e6 f6 (forced) 34. Qxh6 Qc7 35. Qg6! winning (this last move initially escaped my attention) as the mating and queening threats cannot be simultaneously defended.

Although nobody pays any attention to this variation. I think it deserves mentioning

  TheTamale: <Thrajin> Terrible news about Captain Lou! I hadn't heard. I must say, though, he had a healthy life span for someone in that industry.

Well, Dusty Rhodes will probably be in the ring until he's 80.

Good pun, and good timing for pun.

  amadeus: Nice call, <Thrajin>
Oct-15-09  nolanryan: Rybka is quite good, so you gotta respek what it says... but does 30.. Bc8 really give black enough resources to survive white's kingside build-up? What about an old-fashioned plan for white of Qg4, h4-h5

  YouRang: Good pun. :-)
Oct-15-09  RandomVisitor: <nolanryan>The 30...Bc8 line is starting to buckle under deeper analysis:

[+0.51] d=21 31.Qg4 Qc7 32.h4 h5 33.Qg5 Rde8 34.Bd3 Bd7 35.Be2 Rb8 36.Bxh5 Qd8 37.Qxd8 Rfxd8 etc.

Oct-15-09  WhiteRook48: brilliant play
Oct-15-09  nolanryan: Thanks for investigating Randomvisitor!

I bet Kasparov or Anand would have a high win rate against even Rybka after 30. bxc3. Therefore I suspect there was some better way for black to get counterplay than with d5

Oct-15-09  Billy Vaughan: RIP Captain Lou!
Oct-15-09  Prugno: Nice pun, but it looks like Mr. Juswanto was the one having fun during this game, while the girl (or rather, the former Women's World Champion) was suffering pretty heavily!
Oct-15-09  RandomVisitor: Black might have tried <28...bxa3 29.bxa3 Rb8>:

Oct-15-09  redwhitechess: Denny Juswanto is not active today. His last tournament was somewhere in July 2008 according to Fide.

  patzer2: White's 32. Bxf7! is an instructive sham sacrifice, making a strong attack to weaken and undermine the White King's castled position. Too bad Black missed 32...Rb7!, testing the best defense given by Rybka 3 in <RV>'s game analysis post.

  kevin86: Q and B's attack,but it takes a pawn to deliver the knockout punch,but cutting off the defense.
