Feb-01-14  gofer: Not sure that this is quite so "Very Difficult", the lack of choice makes Bxf7+ and obvious choice. The follow up moves very few too, either Qb3+ or Qh5+ and that leads to a quick assessment that the answer is!

<17 Bxf7+ Kxf7>

<18 Qh5+ Kf8> (g6? 19 Qxh7+ Kf8 Qxg6 )

<19 Qxh7 ...>

White's knight is set to come to f5 or h5 to cause maximum damage. Black's knight is a huge problem. White threatens 20 Nxf5 ... 21 Qxg7# One possible try for black is...

19 ... f5?!
20 Nh5! ...

White swaps squares for the knight to attack g7!

20 ... Nf6?
21 Nxf6 winning easily

Another is trying...

19 ... Rxd1+
20 Rxd1 Kf7?!
21 Nf5 Rg8
22 Re7+ Kf8
23 Rxg7 mating

So it looks like black's only try for defense is giving up its knight!?!? But that is pretty pointless as in the long term white will be in a huge positional advantage!

<19 ... Ne5?!>
<20 dxe5 Rxd5>
<21 Nf5 ...>

Black is lost. The only acceptable move is to trade down into a losing endgame...

<21 ... Rxf5>
<22 Qxf5 ...>

~~~

Yep...

Feb-01-14  CopyBlanca: how about 20 N-e4 R-e7 21.Qxg6? I played Spassky in a simultaneous. Afraid of playing Kings Gambit against him tried Alekhine's defense. At least I was one of the last players to lose. Boris was such a gentleman. He got a standing ovation when he came into the room. And graciously signing autographs with just a large B. What a treat to have Boris in sleepy London , Ontario Canada.

  Penguincw: Hmph. This puzzle seems simple enough, if only I saw h7 being unprotected.

Feb-01-14  Nick46: <mike1: this is a discussion which does not get anywhere (or will be ongoing...). But it should be either Munich (English) or Muenchen (the special U with the " on top of it in German).> Good one, mike1. You got in before me. Just for the record (today's piece of useless information)the Italiens call that city "monaco di baviera" (Monaco of Bavaria).
Feb-01-14  PJs Studio: Wow! Blacks seemingly strong (yet passive position) disintegrates in three moves!

I studied Spassky's 100 greatest games when I was a young player and could barely understand him. Super accurate and quite the attacker. His shadow under Fischer is greatly undeserved.

  patzer2: Building the attack slowly with 17. Qh5 doesn't work because 17...Nf8 = to holds for Black.

However after 17. Qh5 the tempting 17...g6?? loses to 18. Bxf7+! Kg7 (18...Kxf7 19. Qxh7+! transposes back to the game) 18. Nf5+ .

  kevin86: White rightly chases the opposing king into the open.
Feb-01-14  Howard: This Munich tournament, however, was somewhat tarnished by the fact that Karpov had to withdraw after only 3-4 rounds due to his father's sudden death. Spassky tied for first I believe.

Incidentally, Spassky won a very nice game from Hubner in this event. It made the Informant, in fact.

Feb-01-14  PJs Studio: Spassky was one of the greatest champions of all time. He was just unfortunate enough to run into a buzzsaw. The greatest player off all time shortened his World Champion status massively as he also would've crushed Karpov in 1975. Badly.
Feb-01-14  Patriot: Material is even.

17.Bxf7+ is my candidate.

17...Kxf7 18.Qh5+

18...Kg8 19.Rxe8+

18...g6 19.Qxh7+ Kf8 20.Nf5

18...Kf8 20.Qxh7 Rxe1+ 21.Rxe1 Re8 22.Qh8+

18...Kf8 20.Qxh7 Ne5 could be played but no real concern.

18...Kf8 20.Qxh7 f5 21.Nxf5 Nf6 looks like a difficult position. 22.Qh8+ Ng8 and I'm a bit lost. So on 22.Qg6 Rxe1+ 23.Rxe1 Re8 24.Rxe8+ Nxe8 seems well guarded and I'm not sure what to do in this line, although white has some compensation.

Feb-01-14  Marmot PFL: Did black touch the king pawn on move 6 and forget to say j'aboube?
Feb-01-14  Patriot: I screwed up a bit on the 18...g6 line, not seeing the pawn on g6 when I considered 20.Nf5--a visualization error. I know that I did not see the position correctly on 18...Kf8 19.Qxh7 f5. And I really screwed up the numbering!

  Jimfromprovidence: Another line to consider is after 17 Bxf7+ Kxf7 18 Qh5+ Kf8 19 Qxh7 g6 20 Qxg6 Qf4?!

The threat is 21...Qg5, seeing 22..c5 with pressure now on g2.

Feb-01-14  morfishine: <Patriot> Nice post covering all bases! The key being <18.Qh5+> and Black is in permanent trouble

  patzer2: <Jimfromprovidence: Another line to consider is after 17 Bxf7+ Kxf7 18 Qh5+ Kf8 19 Qxh7 g6 20 Qxg6 Qf4?!>

The easiest way to deal with this line is to play 20. h4! (instead of 20. Qxg6 ) and transpose back to the final position of the actual game.

However, Fritz 12 indicates White is winning decisively after <17. Bxf7+ Kxf7 18. Qh5+ Kf8 19. Qxh7 g6 20. Qxg6 Qf4> with 21. Nf5! Qg5 22. Qh7! c5 23. g3 when play might continue 23...Be4 24. Qh8+ Kf7 (24... Qg8 25. Qh6+ Kf7 26. Nd6+ Ke7 27. Nxe8 Rxe8 28. Rxe4+ Kd8 29. Rxe8+ Qxe8 30. dxc5 ) 20. Nf5 Qf7 21. dxe5 Rxe5 22. Rxe5 fxe5 23. Nd6 Qd7 24. Qh8+ Ke7 25. Qxg7+ Kd8 26. Qxe5 (+13.34 @ 21 depth on a dual core processor running at 2.1 GHZ).

Feb-01-14  M.Hassan: "very difficult"
White to play 17.?
Equal

17.Rxe8+ Rxe8
18.Bxf7+ Kxf7
19.Qh5+
I think from here, two lines may emerge:

A) 19...........Kf8
20.Qxh7 Nb8
21.Nf4 Qf7
22.Nd6 Qg8
23.Qxg8+ Kxg8
24.Nxe8
White has now a Rook+2 pawns for a bishop and can win.

B) 19...........g6
20.Qxh7+ Kf8
21.Qxg6 (I doubt if this is played) Qf4
22.Nh5 Qg5
23.Qh7 c5 threatening mate on g2
24.Qh8+ Kf7
25.Qh7+ Kf8
1/2-1/2
Black can choose to run the King to e6 but I think that MAY be a draw as well:

25...........Ke6
26.Ng7+ Kf7
27.Nf5+ Kf8
28.Qh8+ Kf7
29.Nd6+ Ke6
30.Qxe8+ Kd6
31.dxc5+ bxc5
32.Rd1+ Bd5
33.f3

  agb2002: The material is identical.

The obvious 17.Qh5 is met with 17... Nf8. This suggests 17.Bxf7+ Kxf7 (17... Kf8 18.Bxe8 + - [R+P vs B]) 18.Qh5+:

A) 18... g6 19.Qxh7+ Kf8 20.Qxg6 (20.Ne4 Rac8 unclear)

A.1) 20... Qd8 21.Nf5 Re7 22.Rxe7 Qxe7 23.Nxe7 Kxe7 24.Re1+ + - [Q+P vs B+N] and attack.

A.2) 20... Nb8 21.Rxe8#.

A.3) 20... Qf4 21.Qh7 Rad8 (21... Red8 22.Re7 + -; 21... Qd6 22.Nf5 + -; 21... Nb8 22.Qxb7 + -) 22.Rxe8+ Kxe8 (22... Rxe8 23.Qxd7 + -) 22.Re1+ Kf8 23.Qe7+, etc.

B) 18... Kg8 19.Rxe8+ Rxe8 20.Qxe8+ + - [R+P vs B].

C) 18... Kf8 19.Qxh7

C.1) 19... g6 20.Qxg6 transposes to A.

C.2) 19... Nb8 20.Qh8+ Kf7 21.Qxe8#.

C.3) 19... f5 20.Nh5 + - (20... Nf6 21.Nxf6 gxf6 22.Qxc7).

C.4) 19... Rac8 20.Nh5 Nb8 21.Qh8+ Kf7 22.Qxg7#.

C.5) 19... Ne5 20.dxe5 Rxe5 21.Nh5 Qf7 22.Nf4 + - [N+P vs B] (the threat Ng6+ looks winning).

<Jimfromprovidence: Another line to consider is after 17 Bxf7+ Kxf7 18 Qh5+ Kf8 19 Qxh7 g6 20 Qxg6 Qf4?!>

The easiest way to deal with this line is to play 20. h4! (instead of 20. Qxg6 ) and transpose back to the final position of the actual game.

However following <17. Bxf7+ Kxf7 18. Qh5+ Kf8 19. Qxh7 g6 20. Qxg6 (20. h4! transposes to the final game position) 20...Qf4>, White still wins decisively with 21. Nf5! Qg5 22. Qh7 c5 23. g3 (position below),

when play might continue 23...Be4 24. Qh8+ Kf7 (24...Qg8+ 25. Qh6+ Kf7 26. Nd6+ Ke7 27. Nxe8 Rxe8 28. Rxe4+ Kd8 29. Rxe8+ Qxe8 30. dxc5 ) 25. Nd6+ Ke7 26. Rxe4+ Kxd7 27. dxc5+ Kxc5 28. Rxe8 (+ 10.74 @ 20 depth on a dual core processor running at 2.1 GHZ).

Feb-02-14  LIFE Master AJ: I found this very simple.

Saturdays and Sundays ALWAYS involve an attack/sacrifice ...

17.BxP/f7+ and 18.Qh5+. Black looks bad, maybe already sunk.
