On 18.h4 I had prepared a fresh idea for my game: 18...Rb8+ and then
A) 19.Ka1 Be8 20.h5 Nd7. For example 21.Rb1 Rc8 22.hxg6 fxg6 followed by Nb6 and/or Bf7. I think Black is quite okay here.


I had the opportunity to test this nice idea of Swiss_Dragon in two corr games, one of them still ongoing. The first one went quite successfull for me:

[Event "RA-2011-0-00126"]
[Site "Lechenicher SchachServer"]
[Date "2011.03.28"]
[Round "?"]
[White "Khlopov, Sergej"]
[Black "Schroeder, Christoph"]
[Result "0-1"]
[ECO "B78"]
[WhiteElo "1926"]
[BlackElo "2136"]
[PlyCount "130"]
[EventDate "2011.02.06"]

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 g6 6. Be3 Bg7 7. f3 Nc6 8. Qd2
O-O 9. Bc4 Bd7 10. O-O-O Rc8 11. Bb3 Ne5 12. Kb1 Nc4 13. Bxc4 Rxc4 14. g4 b5
15. b3 b4 16. bxc4 bxc3 17. Qxc3 Qc7 18. h4 Rb8+ 19. Ka1 Be8 20. h5 Nd7 21.
hxg6 fxg6 22. Bh6 Bf6 23. Bg5 Bg7 24. Rb1 Rc8 25. Bh6 Bf6 26. Be3 Nb6 27. g5
Bg7 28. Bf2 Qc5 29. f4 Bf7 30. Rh3 e5 31. fxe5 Qxe5 32. Rbh1 Rxc4 33. Qb2 Rxd4
34. Bxd4 Qxd4 35. Qxd4 Bxd4+ 36. Kb1 Na4 37. Kc1 Bxa2 38. Kd2 Bf7 39. Rxh7 a5
40. R7h4 Bc3+ 41. Ke2 Be5 42. R4h3 Nc3+ 43. Kd3 a4 44. Rf3 Kg7 45. Rhf1 Be8 46.
Re1 Nb5 47. Ref1 a3 48. Rf8 Nc7 49. c3 Bb5+ 50. c4 Be8 51. R8f2 Ne6 52. Rb1
Nxg5 53. Rb3 Bb2 54. Rb7+ Nf7 55. Rfxb2 axb2 56. Kd4 Kf6 57. Rxb2 Ne5 58. Rc2
Nd7 59. Kd5 Ke7 60. Kd4 Bf7 61. Rc3 Be6 62. Rg3 Kf6 63. Rf3+ Kg7 64. Rc3 g5 65.
Rg3 Kg6 0-1

Also interesting is 16.Ne2.What do you reccomend to play against this move?


Rc7 was played in Negi - Carlsson (not Carlsen) in Corus 2008 where black won a complicated game where both sides had chances.

Yeah, that's what I noticed as well. Initially the computer underestimates the vulnerability of White's King. My line above is meant as a remedy against that.
My instinct tells me that a1 is completely the wrong square. The battery Ka1, Qc3, Bg7 spells disaster.
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

If 18.Ka1 Black can also play the same manouver (Be8, Nd7) starting with 18...Rc8.



That is what happed is that game. I remember analysing it an engines evaluation changed from good for white and ended up with good for black, dispete playing computer top moves almost the entire way.

Here I agree. But what about 21.h6 Bh8 22.Kd2 (getting out of the danger zone), eg Ne5 23.Ke2 Nxc4 24.Rb1 Rc8 25.Rb4 Qd7 26.Rhb1 Nb6 27.Qa3 ? To me it seems to take out pretty much the sting out of Black's pride and joy - that Bishop of the black squares. At the other hand White's rooks need an open file and the c-pawns don't look like a too high price.
It's still a long, hard fight, but White might be somewhat better.

B) 19.Kc1 Ba4 20.h5 Nd7 21.hxg6 hxg6 22.Bh6 Bf6 with good chances for Black. It is important that the bishop is on a4 in this line and not on e8. If the bishop were on e8, Black would get killed by the spectacular 23.Nf5!!

I think 18...Rb8+ is a clear improvement over 18...h5, since I really don't like 18...h5 19.g5 for Black. After 18...Rb8 the h-file opens up, but it doesn't seem to bring White the wished result.

If 18.Ka1 Black can also play the same manouver (Be8, Nd7) starting with 18...Rc8.

Another idea is 18.Bc1!?, which was played by A. Greet against G. Jones (our dragon expert Jones playing the Black side, of course). I think I have found a way to equality here, too, starting with 18...Rb8+.

Hence in my view 18.g5 is the critical move.

18 h4 is indeed critical. In a new in chess yearbook the reply h5 19 gxh5 Nxh5 is assest as unclear but that line is not forced, 19 g5 is also interesting.

Also, 18 Ka1 was played in V Nithander- P Carlsson a few years ago where black won a complicated battle after Rc8 ets.

Do you guys know if there is Houdini for 64 bit-PC?


Yes, the download includes both 32 and 64 bit versions. I've been playing Houdini 1.5 in tournaments against other engines and it's by far the strongest of the free engines.
