  profK: the humble 11...Re8 looks pretty unimpressive.
Nov-23-11  King Death: < profK: the humble 11...Re8 looks pretty unimpressive.>

Donner's play after 11...Re8 doesn't impress much either. Fischer fear is a term I used to hear now and then, but Black's play here was a little on the timid side.

This must be a typo. The event was played in 1966.

Nov-23-11  AnalyzeThis: Basically, black's queen and knight were not contributing much to the game, which would explain why black's kingside burned down.

Jan-10-15  zydeco: This is a nice illustration of Spassky's style when he was at his peak -- his ability to play both aggressively and flexibly, and to cash in on an attack only when he was completely ready.

Spassky played 5.Qe2 because it was a pet line -- "my first love" -- and avoided the Marshall Attack.

10.Rd1 is typical of Spassky's opening play -- a flexible waiting move that gives an opponent the opportunity to go wrong. Donner immediately makes a strategic mistake with 10....Be6, weakening his pawn structure. Spassky says that 10....Bb7 was better -- a more flexible move.

With 16.Bg5, 19.e5, and 21.Rh4, Spassky gets a clear advantage on the kingside.

Once Spassky has a big advantage, he makes a series of very quiet moves to strengthen his position (e.g. 28.Kh1 and 29.f4) before he begins the attack.

Apr-10-15  A.T PhoneHome: You never get a hurried feeling about Spassky's play. While his preference may be tactical chess, he still pays attention to those small details that make his tactical ideas and attacks work.

Very nicely played game by Boris Spassky!

Aug-10-17  ChessHigherCat: 23. Nf6+ Kh8 (Rxf6 loses the exchange and therefore has cooties) 24. Qg6 gxf6 25. Qh6+ Rh7 26. Qg6+ Kh8 and now I'm running out of steam. I'm guessing 27. Rd8 Rhf7 (if Rxe8 28. Rxe8 mates) 28.Qh6+ Rh7 29. Rxf8 Qxf8 30. Qxf8+ at least wins the queen.

Let's checkydoubt maaaaaaaan

Aug-10-17  ChessHigherCat: Spassky didn't guess my moves in the right order, but otherwise he was pretty close :-)
Aug-10-17  stst: Spa must have something interesting, and tricky. Direct:
32.Nf6+ easy for Black would be RxN, but then exR forks R and Qxg7# else
32.Nf6+ Kh8 (ugly too)
33.Nh5 almost any
34.Rd8 RxR
35.RxR+ Kh7
36.Nf6+ gxN
37.Qg8#

Indirect might be:
32.Qg6 looks in control, Black may go Rf7
33.Nd6 would be hard to defend...
Bed time...

Aug-10-17  drollere: i had Nf6+ Kh8, Rd8 R(7)f7, Rxf8+ Rxf8, etc. i do not understand why 34. Rxf8# did not follow 33. .. Rc7!
Aug-10-17  ChessHigherCat: I just took a nap and I think I must have been dreaming before I finished my analysis. Here's what I meant, but it only wins a rook: 32. Nf6+ Kh8 33. Qg6 gxf6 34. Qxh6+ Kg8 35. Rd8 Ree8 36. Qg6+ Kh8 37. Rxe8

  perfidious: <smitha1: Does 32... Kf7 keep Black in the game?>

Your line is met by 33.Qh5+ g6 34.Qxh6.

Aug-10-17  Whitemouse: 32...Kf7 33.Qh5+
Aug-10-17  BxChess: How does white continue if 33...Ref7?
Aug-10-17  goodevans: 32.Nf6+ may be quickest but white looks to be in such total control that surely other moves win too.

I'd have played <32.Qg6>. Is there a defence to that?

Aug-10-17  clement41: Nice game by Spassky.
This Qe2/Rd1 plan is also seen sometimes in the open Ruy Lopez (known as the russian line I reckon). It is interesting how the centre battle gradually turns in white's favour: white rightly avoids 10 cd? Nxd4 11 Nxd4 Qxd4 where black would have a strong bind against d3 and a nice outpost on d4. Spassky trades on e6 only after (the clumsy enough) 11...Re8?! so that the rook gets funny there. I like a lot 19 e5! taking space, fixing e6, and not rushing to capture on d4. Spassky rightly leaves the tension by not taking with his pawn on b5; anyway if black takes on c4 his structure is torn apart. Last, the knight is gorgeous on d6 where it both attacks and is a file-clogger. These are positional considerations that no doubt underlay the tactics that finished Donner off.
Aug-10-17  patzer2: Today's Thursday puzzle solution's first move <32. Nf6+!> seemed obvious to me as 32...Kf7 33. Qh5+ g6 34. Qxh6 +- (diagram below)

wins easily due to the threat of 35. Qh7#.

However, after <32...Kh8!?> Black sets a tempting little trap to entice 33. Qg6? = 0.00 @ 43 depth, Stockfish 8 (diagram below)


click for larger view

which results in a forced draw by repetition after 33.Qg6? gxf6 34.exf6[] Rh7[] 35.Rd8 Nd5 36.Qe8[] Kg8[] 37.Qg6+ Kh8 38.Qe8 Kg8 39.Qg6+ Kh8 40.Qe8 =.

White avoids the trap and wins instead with <33. Rd8!> Nd7 34. R8xd7 Rxd7 35. Nxd7 +- (+6.56 @ 32 depth, Stockfish 8.)

Aug-10-17  malt: Got 32.Nf6+ Kh8 33.Rd8 Ref7 34.Qg6 R:f6
(34..gf6 35.Q:f7 )
35.ef6 gf6 36.Qf7
Aug-10-17  ChatGrognon: First one I got : )
Aug-10-17  catlover: The hard part of this puzzle if finding 32 Rd8.
Aug-10-17  patzer2: <catlover> I think you meant 33. Rd8 +-.

  takchess: My 20cent intuition tells me whites moves are Queen g6 followed by Nf6+ followed by taking a rook and liquidating blacks position and perhaps leading to mate.
Aug-10-17  Rama: Surely 33. ... Rc7, is a typo for Rf7?
