If 21...Qc6 22.Nd4 Qa6 23.Rd6 Qa5 24.Qxc4+ Qc5 25.Rc6+! Qxc6 26.Nxc6 bxc6 27.Qxc6++

|Jun-01-04|| ||ConLaMismaMano: Very good game by Spassky. |
|Aug-17-04|| ||Deck: Rd6!! is astoninishing and brilliant. |
|Jun-26-07|| ||Benzol: <Whitehat1963> <What's the finish?>|
|Jun-26-07|| ||MaxxLange: <21...Qc6 22.Nb5> looks crushing, yes. The Queen can't defend against both Nxa7 mate and against Qxc4+|
|Jun-27-07|| ||Wolfgang01: 15. … Nh6 looks very weird. I think 15. … Nf6 is better to control the center. Alekhine and Tarrasch were right, when the fighted for the center. This would prevend 16. d5.|
|Jun-27-07|| ||beatgiant: <Wolfgang01><15. … Nh6 looks very weird. I think 15. … Nf6 is better>|
After 15...Nf6 16. Ng5 hitting f7 looks strong.
|Oct-17-08|| ||PinnedPiece: Whoa!
Did I not get this one or what?
I not get this one.
|Oct-17-08|| ||Terry McCracken: 19. Rd6!!|
|Oct-17-08|| ||al wazir: I couldn't decide between 19. Rd6 and 19. Nd4, which I think also wins.|
For example, 19. Nd4 Bxd4 20. R1xd4, threatening 21. Rxc4 and 21. Nb5. If 19...Qb6, then 20. Qxc4. If 19...Qa6, then 20. Ndb5, threatening 21. Bc7, wins at least an exchange.
|Oct-17-08|| ||sleepyirv: I'm very impressed by Spassky in this game, very nice finish. I wasn't very close today.|
|Oct-17-08|| ||gazzawhite: <PinnedPiece> I wasn't even close either, so don't feel bad (mind you, I'm not very good so that doesn't say much).|
I would never have imagined such a quiet, "silly-looking" move. The only time I would make such a move is if I was not watching what I was doing!
|Oct-17-08|| ||TheWizardfromHarlem: <gazza> the line between genius and insanyit is very thin|
|Oct-17-08|| ||TCS: Very interesting positions with the following
1. White Bishop on h2-b8 diagonal is hemming in the King
2. White's two Rooks on the d file are also hemming in the king
3. Whites pieces are more centralised than blacks who as with a Rook on a8 and Knight on h6. Whenever this is the case there is often something interesting about to take place.
4. There is a mate if White Knight on c3 can get to either a7 via b5 or e7 via d5 and note neither of these squares is well defended - only the black bishop
5. There is also a mating opportunity if the Queen can get on the c file.
The problem is how to take advantage of these when black is wanting to play Re8 and Ne5 to centralise
So many options. At this point I felt that getting the Knight to b5 was the right thing to do. No more than that so how too...
19. a4 struck me as useful too so its possible to play 20. Nb5 but after Re8 and Ne5 a4 looks too slow
19 Qxc4 is a no go becuase of 19...Be3+...oops
19. Rxc5 struck me as useful and if 19...Qxc5 then Rd5 looks great. Queen has to move away and Nb5 looks very strong especially with Qxc4 also threatened. The problem is 19...Nxc5.
I looked hard and realised that the position above could be achieved by
19.Rd6 if 19...Bxd6 20. Rd6 Qc5 21. Rd5
Does Black have to accept the sacrifice? Yes, becuase the Queen can't escape :-)
Not a lot of depth analysis just lots of good feelings about the resulting positions with Rd6 looking like the way to go followed by getting the Nb5 and threatening mates on a7 and Qxc4.
|Oct-17-08|| ||TCS: 'Good Feelings' won through today.
There is always a limit to how far you can go with analysis and it decision making comes down to having a good plan which has a number of options to continue. In this case the build up of threats of Na7 and Qxc4 whilst stifling any possibility of counter play.
|Oct-17-08|| ||MostlyAverageJoe: <al wazir: I couldn't decide between 19. Rd6 and 19. Nd4, which I think also wins.>|
Nd4 was my choice for the same reasons as you already have outlined. I just thought is appeared to be too obvious for Friday.
After initially preferring Rd6, Hiarcs likes Nd4 better. The first five plies in each line are reasonably certain (19 plies, about 1 hr of runtime).
1. (+9.19) 19. Nd4 Bxd4 20. R1xd4 Nb6 21. Rd6 Rxd6 22. Rxd6 Qe8 23. Re6 Qd7 24. Re7 g5 25. Rxd7 Kxd7 26. Be3
2. (+7.11) 19. Rd6 Bxd6 20. Rxd6 Ne5 21. Rxc6 Nxc6 22. Qe6 Rd7 23. Na4 g5 24. Nc5 Rhd8 25. Nxd7 Rxd7 26. Bd2 Nf7 27. Qxc4 Nd6 28. Qg4 Nf7 29. Be3 Nd6 30. Qa4 a6
|Oct-17-08|| ||TCS: Addendum: I didn't 'see' Nd4 at all.
Looking back I suspect that this was because I liked the look of the connected White Rooks on the d file...
|Oct-17-08|| ||DarthStapler: I got the first two moves|
|Oct-17-08|| ||Woody Wood Pusher: This is one of the most interesting puzzle positions I have ever seen, there are so many possibilities in it! |
I realized 19. Rd6 was the best after a LOT of calculation.
The critical line is 19.Rd6,Bxd6 20.Rxd6,Qc5 21.Rd5,Qb4 22.a3,Qb6 23.Qxc4+,Qc6 24.Nb5,Rf8 25.Nxa7+,Kd8 26.Nxc6+,bxc6 27.Qxc6, + -
There are many beautiful other lines though.
|Oct-17-08|| ||johnlspouge: Friday (Difficult):
Spassky vs Larsen, 1978 (19.?)
White to play and win.
Material: Even. The Black Kc8 is stalemated. White has a battery Rd1 and Rd5 facing Nd7 and Rd8. The Black Qc6, Kc8, and Rd8 protect Nd7; Kc8 and Rh8 protect Rd8. The Black Rh8 and Nh6 are presently out of play, but White needs to activate Nc3, Nf3, and Qe2 for a local superiority and sacrificial attack against Kc8. The Black Qc6 is limited in scope and potentially overburdened with defense, not only of Bc5 and Nd7, but more subtly, of Pc4.
Candidates (19.): Qxc4, Ne4, Nd4
19.Nd4 (threatening 20.Nxc6 or 20.Qxc4)
Because both 19.Qc7 Ne6 and 19.Qb6 Qxc4+ are infeasible, Black has 2 options:
(1) 19…Qa6 20.Ndb5 (threatening 20.Qxc4 again)
20…Qc6 21.Rxc5 Qxc5 [Nxc5 22.Nxa7+]
22.Nd6+ Kb8 23.Ne4+
After 23…K moves 24.Nxc5, White has Q+B for R+N; after 23…Qc7 24.Bxc7, Q+B for R+B.
(2) 19…Bxd4 20.Rd6 Qc5
[20…Qc7 21.R6xd4 then eventually Rxc4 winning Qc7]
21.R1xd4 (threatening 22.Rxc4, 22.Qxc4, or 22.Qe6+)
21…Ne5 22.Bxe5 (threatening 22.Rxc4)
Black cannot productively capture anything [22…fxe5 23.Rxc4, 22…Qxe5 23.Qxc4+, 22…Rxd6 23.Rxc4], so he is down a piece.
Toga II 1.3.1 verifies my variations, evaluating 19.Nd4 at
[ply 15/58 time 01:32 value +3.77].
Spassky's 19.Rd6 is both elegant and better, however:
[ply 15/49 time 01:01 value +5.85].
|Oct-17-08|| ||AhmetMTF: Hi everybody. I couldn't find the move Rd6, however, I played a very different line which needs your evaluation. (since I'm just an amateur in chess.) At the end of my line, if it's correct, Black would have 2 rooks and a knight, while white has 1 rook, 2 knights and a bishop. However, white also have a positional advantage where Black king is open to threats. Please evaluate my line, at least briefly: 19.Qxc4!? - Be3+ 20. fxe3 - Qxc4 21. Nb5! (this move threatens mate in one move with Nxa7++) - Qxa2 22. Nd6+ - Kc7 23. Nb5+ - Kb6 24. Bc7+ - Kc6 25. Nfd4+ - Kxd5 26. Nc3+! - Kc5 27. Nxa2 - Rde8 28. Nb3+ etc. (It may be too amateur, but I think it is at least beautiful. :))|
|Oct-17-08|| ||Patriot: This was difficult to say the least. There are so many forcing moves to consider--too many to analyze in too little time. I looked at Rxc5, Rxd7, Bxh6, Nd4, and Rd6. Rd6 looked the most appealing because it limited black's options compared to other candidates. After analyzing the obvious 19.Rd6 Bxd6 20.Rxd6 Qc5, I asked myself the question "And now what?" I didn't even consider 21.Rd5 because even after looking at the position nothing stood out after 21...Qc6 for example. Therefore I couldn't bring myself to accept 19.Rd6 as the right move since white is down material and from the best I could tell, no other candidates that lead anywhere. But of course that was incorrect as after 21...Qc6 22.Nb5 threatens mate and a queen-king fork. Plus Qxc4+ is threatened if Qb6. I just wonder how much time Spassky used before playing Rd6?|
|Oct-17-08|| ||cyclon: Oh-hoh! -Qb4, Rb5/-Qb6,Qxc4+ Qc6 (-Nc5,Rxc5+ Kd7,Bxh6) Nb5. When I was a boy, I was wondering why certain particular players or rather (as I understand it now) `figures`, become World-Champions in Chess. After decades I have started slowly, very slowly to understand.|
|Oct-17-08|| ||Patriot: AhmetMTF: Your line is very interesting. Maybe 19.Qxc4 Be3+ 20.fxe3 Qxc4 21.Nb5 then maybe 21...Ne5 22.Nxe5 fxe5 23.Nxa7+ Kb8 24.Rxd8+ Rxd8 25.Rxd8+ Kxa7 and it looks like black is winning. Looks like a very complicated line, so white should be very leary of playing Qxc4 because of the tactic you pointed out.|
