  kevin86: How about this odd finish: 43...♗xg7 44 ♘xg7+ ♔xd6. White will eventually queen his lowly a2 pawn and will win!!!
May-26-09  WhiteRook48: two bishops vs two knights?!
Mar-10-11  hottyboy90: Lovely technique by Fischer although I got this one fairly quickly but I would never had been able to reach a position like that against someone of Spasskys caliber so I will just shut up now. Enjoyed the endgame very much all the same.
Mar-12-11  Damianx: Amazing the best ever he wins this on moves 18/19/20
Mar-12-11  hottyboy90: really? them moves seemed pretty insignificant to me. I think the decisive advantage for Bobby came after 28...Rxe3
Feb-04-13  RookFile: One of history's great Ruy Lopez players relies upon playing d3 rather than the more customary d4 break. In doing so, he preserved the option of a later d4, and kept Spassky guessing.
Jul-14-13  Ulhumbrus: 17...c4 seems unnecessary. 17...Qxd5 takes greater space.

On 22 bxa5 White has a pawn but his queen side is ahattered, while Black has more space as well as the bishop pair. Black has the advantage, then. Instead of 22...f5, 22..Rac8 or even 22..Re6 followed by 23...Rae8 develops the queen's rook.

Jan-02-14  RookFile: After your 17..... Qxd5, can white play 18. c4?

Mar-14-14  Ulhumbrus: <RookFile: After your 17..... Qxd5, can white play 18. c4? > It seems so. In that case 16...d5 may be premature but on 16...d5 17 ed Bd6 may be worth considering.
Dec-26-14  gmelfranco: interesante ganancia por parte de fisher-- muy creativo...

Mar-09-17  YouRang: Thursday 40.?


click for larger view

Obviously, this is about promotion tactics. I decided to start with <40.Ke4>


click for larger view

I liked how the K, N and P conspired to make a wall along e5-e6-e7, and I liked how I was free to push the g-pawn since the N was guarded. For example, black can't play 40...Bd5 due to 41.g5+!

The hard part is guessing black's best reply. Perhaps <40...Bc1> to prevent g5. In that case, I like <41.Nd4> which (1) supports d6 by guarding e6, and (2) sets up Ne6 to support g5 push. I would expect <41...Ke7> to stop d6.


click for larger view

Now <42.Ke5> supports d6.

What can black do?

- 42...Kd7 43.Ne6 and the N controls the key dark squares to push the g-file.

- 42...Ba3 (to stop d6) 43.Nf5 supports d6 as well as g7.

- 42...b4 43.d6+ Kd7 44.Ne6 supports g5 and then Nc5+ supports d7.

Looks like white won't be stopped.

~~~

I see that white opted for <40.d6>, which also works, and is rather cuter.

  Benzol: An echo from the past Spassky vs Fischer, 1966
Mar-09-17  Abdel Irada: ∞

<<+> "Passed pawns must be pushed" <+>>

This is one of those endgames where normal rules don't apply. Ordinarily in such a position, one would play 40. Ke4, centralizing the king and restricting Black's options. But here one must be careful, because unnecessary king moves can allow counterplay sufficient for drawing chances.

On the other hand, ordinarily one should not push pawns recklessly, lest they be picked off, and one's winning chances with them.

But here the fastest path to victory turns out to be pushing both pawns so as to tie down Black's king and bishop before going off to harvest the queenside pawns.

<40. d6!, Ke6>

That's one piece committed; now for the other.

<41. g5!...>

This didn't quite work last move, but it does now. If 41. ...Kxf5? 42. d7 wins because f6 is not available for the bishop.

<41. ...a5>

Black tries to mobilize his pawns for counterplay, for want of a better option, but it is too slow.

<42. g6, Bf6>

Black has to get the bishop into the action now, before White plays 43. Nd4, locking it out and winning.

<43. g7! >

Black is approaching zugzwang. Next White will play d6-d7, paralyzing the defenders, pick off the a- and b-pawns, and eventually win with K + RP + N vs. K.

Mar-09-17  gofer: Hmmm, I don't like black's chances much, but still there may be chances for black to equalise.

<40 Ke4 ...>

This sets up the king march to h7 if black plays Ba3...

40 ... Ba3
41 d6 Ke6 (to stop Kd5)
42 g5 Bxd6
43 Nxd6 Kxd6
44 Kf5 Ke7
45 Kg6 Kf8
46 Kh7

...but it also allows the king to go to c6 or e6 if black plays Bc3-Ba5-Bd8...

40 ... Bc3
41 d6 Ke6 (to stop Kd5)
42 g5 Ba5 (Bb4 g6 Bxd6 Nxd6 Kxd6 g7 )
43 g6 Kf6
44 g7 Kf7
45 Kd5 Bd8
46 Kc6

So the only question remaining is what about Bc1?

<40 ... Bc1>
<41 Nd4 Ba3>
<42 Nc6 Bd6>
<43 Ne5! ...>

This seems a little convoluted for a <Thursday>, so what have I missed!?

~~~

Ahh! Okay, that was "easy"...

Mar-09-17  clement41: After 43...Bxg7 44 Nxg7+ Kxd6 45 Kd4, black will go ...b4 then ...a4 (if ...a4 first, then a3 fixing the Q-side, although the pawn sac ...b4 ab a3 always must be monitored). The moment black plays ...b4, white must reply a4 if he wants to play for the win obviously. The knight must come back into play, capturing black's pawns and shepherding white's pawn.

However in the game, it is not immediately obvious how white will improve, against the Black setup Kg8/Bd8

Mar-09-17  eaglewing: Now, if 40. d6 is a winning move, is 39. ... Kf6 really a losing move? Instead of Kf6 which move could draw? I suspect 39. ... Bf6 could be better, taking control of g5 and d8, the squares which both passed pawns still have to take, but is it enough?
Mar-09-17  Carlos0012358: Too famous a game. Not good for a puzzle.

  morfishine: Friday usually gives me alot of trouble but this one was easy, Wednesday-ish

*****

Mar-09-17  saturn2: I did not get it but I understand now it is about limited possibilities of the bishop to control the square d8.

Since white is a pawn up there should be other winning moves like Ke4 or Nd4.

Mar-09-17  clement41: The pos after 26 Nf4 exd2? makes for a good enough calc. training. There are the lines starting 27 Rxe8+ Rxe8 28 Nxd5 Re1+ that should yield (note the nice Kh2! move allowing the zwichenchach Nxf6+). And the lines starting 27 Nxd5? with sublines 27...de=Q+ and 27...Rxe1+?(which should yield respectively and )
Mar-09-17  wtpy: Morfishine, How do you usually do on Thursday?
