| Jun-25-05 | | kevin86: There are three squares that must be unattacked by enemy forces to allow castling. The original square that the king is on-in other words,the king may not be in immediate check. The intervening square-the king may not cross over a check. The landing square,it is obviously illegal to put your king into a direct check. None of these affect the rook:It may be in danger or pass over an in-danger square. Of course,castling must be the initial move by king and castling rook. That is the only rule that affects the rook. I'm not sure if there can be a "local rule"-of this type---Though there may be some in other circumstances-eg.fifty move rule,repitition rule etc. |

| Jun-25-05 | | patzer2: Here's some analysis with Fritz 8 and the ChessGames.com Opening Explorer: <1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Qc7!?>
Black invites White to take the Knight and double his pawns.<8. Bd3>
White did OK taking the challenge with 8. Bxf6 in Topalov vs Anand, 1997, but the position is double edged as Black still
has lots of counterplay with the two Bishops as in C Velasquez vs Leitao, 2004 . <8...Nbd7> Worthy of consideration, and in
line with Black's intention in playing 7...Qc7!?, is 8...b5!? as in K Spraggett vs Gelfand, 1990 and B Jonasson vs Wojtkiewicz, 1994 . <9. Qe2 b5 10. O-O-O Bb7> Here I like 10...b4!?,
transposing to the 8...b5!? recommendation in the Black victory from the
Spraggett vs. Geller game link above. <11. Rhe1 Be7 12. e5 dxe5 13. fxe5
Nd5 14. Bxe7> Apparently White overlooked a strong winning shot with 14. Nxe6! fxe6
15. Qh5+ Kd8 16. Nxd5 Bxd5 17. Bxe7+ Kxe7 18. Qh4+ g5 19. Qxg5+ Ke8 20. Qg7 Rf8

and with best play can fully equalize.
<15. Qg4!?> Spassky decides to take a little risk and complicate for winning
chances, since the alternative 15. bxc3 gives Black easy equality after 15. bxc3
Kxe7 16. Qg4 Bd5 (Not 16... Qxc3? 17. Nxe6 fxe6?? 18. Qxg7+ ) 17. Be4 Bxe4
18. Rxe4 Rhg8 19. Qg5+ Ke8 20. Nxe6 fxe6 21. Qh5+ Ke7 (21... Kd8? 22. Red4

Rxd7+ ) 22. Qg5+ Ke8 23. Qh5+ Ke7 24. Qg5+ Ke8 =, with a draw by threefold repetition.
<15... Nxd1 16. Nxe6 Qc6??> This is the losing move. Black missed a last chance to hold
with 16...fxe6! 17. Bd6 (Not 17. Qxg7? Nf8! 18. Qxh8 Qxe7 19. Rxd1 Bxg2 20. Qg8 Bd5 
) 17... Qb6 18. Qxe6+ Kd8 19. Qe7+ Kc8 20. Bf5 Bc6 21. Qxg7 Rd8 22. Rxd1 Qe3+

forcing a draw by threefold reptition. <17. Nxg7+ Kxe7 18. Qg5+ f6> (18...
Kf8 19. Nf5! Qg6 20. Qe7+ Kg8 21. e6!! ; 18...Nf6 19. Be4! ) <19.
exf6+ Kd8 20. f7+ Kc7 21. Qf4+ 1-0> Black resigned, but play could have continued
21...Kb6 (21... Qd6 22. Ne6+ Kc6 23. Be4+ ; 21... Kc8 22. Re8+ Rxe8 23.
fxe8=Q#) 22. Re6 1-0 |
|
| Jun-25-05 | | jahhaj: <Richard Taylor> In your line, 20...♘f8 and Black is winning easily enough. I think you are probably right that Spassky hadn't seen all the way to a win when he played Ne6. If a win is there then it is sufficiently deep that Spassky would have had to have been a God-like genius to see it all. |
|
| Jun-25-05 | | thesonicvision: 21..Kb6
22. Re6 wins the queen
21..Qd6
22. Ne6+ Kc6
23. Be4+ wins the queen
of course, if the king steps on
the back rank, white will promote the
f-pawn after exchanging rooks.
about 16. Nxe6:
in a real game, this would be easy
to see as a candidate move- but
EVERYONE here would reject it in
torunament play after being unable to
compensate for the severe material
disadvantages white would suffer.
if you were able to see the the
entire winning line, i am very much
impressed.

| Jun-25-05 | | patzer2: Correction to my analysis above. I meant to refer to the Spraggett versus Gelfand (not Geller), 1990 game link above in recommending 10..b5!?. |
|
| Jun-25-05 | | Geronimo: Oh <thesonicvision> you're praise for us is too optimistic... I would have 16ed with NxE6 in tournament play because I'm too sloppy to calculate all the severe material disadvantages! The point for me today (and maybe I speak for others who can't or don't calculate so deeply) is that I was able to see the tactical advantage of the text move and some possible lines after a short assessment of the position. Perhaps this is one way in which working puzzles really benefits speed play, as opposed to long games. In tournament play I would never have gotten to this position, and in my speedchess addiction I'm likely to find myself in similar - but never identical - tactical surroundings.... |

| Jun-25-05 | | Helloween: <patzer2>, I think that 14.Nxe6 is not winning by any means. 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bg5 e6
7.f4 Qc7 8.Bd3 Nbd7 9.Qe2 b5 10.O-O-O Bb7 11.Rhe1 Be7 <(here I think 11...O-O-O!? 12.Bxb5! axb5 13.Ndxb5 Qa5 14.Rxd6! leads to a very interesting game, check it out)> 12.e5 dxe5 13.fxe5 Nd5 14.Bxe7 (and here 14.Nxe6!?

|
| Jun-25-05 | | patzer2: <Helloween> I guess you're right. After 14. Nxe6!?, it would appear Black can fully equalize with 14... Bxg5+ 15. Nxg5 Nxc3 16. bxc3 Qxc3 17. e6 Qa3+ 18. Kd2 Qa5+ 19.c3 Qxa2+ 20. Ke3 Qxe2+ 21. Rxe2 fxe6 22. Nxe6 Rb8=. After 16...fxe6 17. Bd6 Qb6 18. Qxe6+ Kd8 19. Qe7+ (19. Bf5 Bc6 20. Qe7+ Kc8 21. e6 Nf6 22. Qxg7 Rg8 23. Qxf6 Ne3 24. Bxh7 Nd5 25. Qf7 Re8 26. Bf5 Ne3 27. Bh3 Nd5 =, Fritz 8 assesses the position as fully equal. However, I must admit it is an unbalanced position with White having four pawns for the Rook and the initiative. Fritz 8's suggestion in this line is for White to take a draw by repetition of moves with 28. Bf5 Ne3 etc., and it is unclear as to whether other options lead to a winning advantage for White. So, it would appear both 14. Nxe6!? and 16. Nxe6!? give White some winning chances against likely mistakes in a difficult position, but that with accurate play Black has reasonable drawing chances. However, I must agree that Spassky's idea to defer and play the sacrifice 16. Nxe6!? gives White the best winning chances, and was therefore the right choice. |
|
| Jun-25-05 | | Nezhmetdinov: The really great move here is 15 QG4!? Spassky had to see everything from there - that would have been a real puzzle! |
|
| Jun-26-05 | | nikolaas: <jahhaj: <nikolaas> You don't allow castling over an attacked b8 square? Weird!> I'm a weirdo. An interesting idea would be:
16.Nxe6 fxe6 17.Bd6 Qb6 18.Qg5
-a)Qd8 19.Qxg7 Rf8 20.Qxh7 with the terrible threat Bg6
Though I'm afraid Nf6 might save the day.
Another idea is also 18.Bg6 hxg6 19.Qxe6 Kd8 20.Rxd1 Kc8 21.Qf7 with the idea of pushing the e-pawn.
Can someone please check these lines with a comp?
|
|
| Jun-07-13 | | olpa: Note that after 16.Nxe6 fxe6 17.Bd6 Qb6 18.Qg5 Qd8 white does not play Qxg7, but 19. Qg6+ hxg6 20.Bxg6 mate. And yes, 18...Nf6 holds the position. |
|
| Sep-21-14 | | SpiritedReposte: Opening preparation? No brakes on this attack from Spassky. |
|
| Mar-10-18 | | morfishine: No, 18...Nf6 does not hold the position because now White breaks in like a tornado with <19.Qxg7> Threats: (1) mate at <e7> (2) the Knight on <f6> (3) the rook on <h8> & (4) the Bishop on <b7> Too much

| Jul-29-19 | | N.O.F. NAJDORF: thesonicvision: 21..Kb6
22. Re6 wins the queen
When I was a youngster, I saw this game with analysis in B.H. Wood's monthly CHESS. I can't remember the analysis, but looking at the game now, I think 21 ... Kb6 loses to
22 Qd4 +
If then 22 ... Qc5
23 Ne6 + wins the queen
If 22 ... Kc7
23 Ne6 + wins the queen, because if 23 ... Kc8,
then 24 Qxh8+
If 22 ... Nc5
23 Re6
followed by Rxc6+ and then either Ne6 or Be4+
but I'm willing to be corrected! |

| Apr-11-20 | | Gaito: I have an old book in Russian language:
(Волчок. Стратегия атаки на короля - Шахматная библиотека, 1980), a very good book the way, that offers a thorough analysis of this game (pages 22,23,24). According to the author (Волчок) the critical move was 16...Qc6? The correct defense was 16...fxe6 17.Bd6! Qb6!, and then 18.Qg5 doesn't work on account of 18...Nf6! (but not 18...Qd8?? 19.Bg6+ with mate). For example: 19.exf6 Qxd6 20.fxg7 Rg8 21.Bxh7 Rxg7 22.Qxg7 O-O-O 23.Bd3 Nf2 (diagram)

| Apr-11-20 | | Gaito: Another variation given by Волчок in his book is this one:(after 16...fxe6 17.Bd6 Qb6 18.Qg5 Nf6! 19.exf6 Qxd6 20.fxg7 Rg8), and now 21.Rxd1 (instead of 21.Bxh7), 21...Bd5! (but not 21...Qe7? 22.Bxb5+ axb5 23.Qh5+ Qf7 24.Qxb5+, etc.) 22.Bxh7 Kd7 23.Bxg8 Rxg8, reaching the following position:

| Apr-11-20 | | Gaito: After 16...fxe6 17:Bd6! Qb6!, White might try 18.Qxe6+!? Kd8 19. Bf5! Bc6 20.Rxd1 Re8 21.Qf7 Qe3+ 22.Kb1 Qe2! 23.Kc1, and White should accept the draw by repetition of moves, since 23.Rc1?! Qd2! (preventing 24.e6) 24.Qxg7 Ra7 25.Qxh7 Qd4! 26.c3 Qf2, seems to be losing for White, see diagram:

| Oct-18-20 | | SpiritedReposte: Interesting. |
|
| Oct-18-20 | | sudoplatov: I ran a short exploration with Stockfish (I think that was the program) after 16...fxe6 17.Bd6 Qb6, 18.Qxe6+ Kd8, 19.Bf5 Kc8, 20.Rxd1.... White seems to gradually improve his position. |

 | | GrahamClayton: Was there a brilliancy prize given for the best game played in the 1973 USSR Championship? This game would have to be a candidate. |

| Jul-27-23 | | N.O.F. NAJDORF: 21...Kb6 22. Re6 Nxb2 23. Rxc6+ (23. Qd4+ Ka5 24. Rxc6 Nxd3+ 25. cxd3 Bxc6) Bxc6 24. Qd4+ Kb7 25. Kxb2 Rhf8 26. Qf4 Bd5 27. Be4 Kc6 28. Bxd5+ Kxd5 29. Qf5+ Kc6 30. Ne6 Rh8 31. f8=Q Rhxf8 32. Nxf8 Rxf8 is hardly a quick win. |
