Jan-29-06  euripides: Black sits tight for fifty moves and then lunges with 66..a4. Three possible interpretations: he lost patience: he missed or underestimated 68 Nxd6 and thought he had an attacking chance: or he thought White was finally threatening to do something with b4. Any takers ?

  Benzol: I suppose it's possible that the original gamescore was written in English Descriptive notation and had Black's 73rd move as 73...Q-N1 without specifying whether it was Queens Knight One or Kings Knight One. Someone subsequently might have just assumed it was Kings Knight One without checking properly.

Jan-29-06  ckr: <Benzol> a common mistake even when it is correctly scored as Q-QN1.

<CG> Glad you found the correction, now I can remain a patzer.

Jan-29-06  EmperorAtahualpa: LOL, obviously there was a huge difference between the two positions.

80.f4 is a brilliant move, which I did not spot at all. Better luck next Sunday.. :s

Jan-29-06  notsodeepthought: <cg.com: we now are the only online source where you can witness this game as it was actually played.> See? The annoying criticism from puzzled kibitzers was all to the good in the end.
Jan-29-06  psmith: I don't know if this should be called a puzzle. Or at least, to really "solve" it you surely have to see a lot. Black's moves don't all seem forced and there seem to be several chances for a better defence after 80. f4. For example, how does White force a win after 81...Qf8?
Jan-29-06  LIFE Master AJ: Good play by Rossolimo.
Jan-29-06  joeaverage: Why did black play 80...Rba7?
Jan-29-06  Juarez: 80.Rc7- RXC7 81.RXC7-QXC7 82.QC6-QXC6 83.dxc6 Ke8 after that am lost.
Jan-29-06  psmith: First, in reply to my own comment, I set Old Fritz (5.32) to thinking about 81... Qf8 and the conclusion seems to be that white has a plus after 82. Qe3. But there are many lines.

Second <joeaverage> 80. f4, it seems that taking the pawn either way is bad. So the question is what Black should play instead of 80...Rba7. He has to move, after all (it's not exactly zugzwang, but similar, I think).

Jan-29-06  vangelis: This is just a test... wonderful page
Jan-29-06  psmith: <joeaverage>
So, the question is, what should Black do after 80. f4!!

If he takes the pawn 80... exf4, 81. Qxf6 wins.

If he takes the pawn 80... gxf4, 81. Qh3 followed by g5 is going to crush him: 81... Qf8 82. g5+ f5 83. exf5 Kd8 84. f6 Rd7 85. Qc3 Ke8 86. Rc8+ etc (Fritz) or 81... Kd8 82. g5 fxg5 83. Qe6.

So, he can't take the pawn. He has to keep his Queen and Rook covering c7, so random Queen moves like 80... Qf8 are out.

He needs to keep his Queen and his Rook on his first rank, in order to meet 81. fxe5 fxe5 82. Qf3 with 82...Qf8. (If he moves 80... Qa7 or 80... Raa7 he will have no defense to this line.)

He can't move his King to the first rank without causing the same problem (blocking ...Qf8) and if he moves 80...Ke7 he leaves open 81. Rc8 winning.

So the main alternatives are 80...Rba7 (as in the game) and 80...Qd8.

So, what about 80...Qd8? This is met by 81. fxe5 fxe5 82. Rxd6+! (Fritz) Kxd6 83. Rc6+ Kd7 84. Qxe5 with a winning attack. (This is still complicated but analysis with Fritz shows it to be winning.)

So, Rba7 is virtually forced!

Jan-29-06  dakgootje: Well i saw the first move, but didnt see blacks response so calculated wrong right after the first move
Jan-29-06  JoeStrummer: Got the idea, but couldn't see anything positive in moving the pawn chain.

Does this position remind anyone of the games you would have against the chess computers (software and standalones), say, ten or fifteen years ago? These positions were very common, before the computers got strong enough to open the game up at an opportune moment. you would just block the position with pawn, pile on an open file, and then maneuver your king or Knight to the correct place for a sac, then break through. The old computers weren't strong enough to understand the sublte movements of a Knight or Bishop making a long journey to another part of the board for a breakthrough. Today's position reminds me of a lot of those games against the early chess computers.

Jan-29-06  Cogano: Alas, I didn't get it, but love the ending. It is most beautiful & brilliant. Many thanks to chessgames.com for bringing it to my attention. Take care all and have a great day. Cheers!

  Richard Taylor: I found 80 f4 but didn't follow all the compelxities - my idea was e.g.

80. f4 now if gxf4 81. g5 hxg5 and 82. h6 or Qh3+ or both. 82. Qh3+ Kd8 83. Qd6

or 81. fxg5 Qh3+ and it has to be winning

I then thought after 80. f4 Qed8 81. fxe5 fxe5 82. Qf3 was winning but thee's Qf8 I now see -

This game was a comical dance of kings and manoeuvering almost as if the two players were cobras trying to hypnotise the other... White missed out on playing h6 at one stage...alsmost as if he wanted a long strange game like this ending in brilliancy!

  Richard Taylor: I didnt see the postion with the Q on g8 - that must have been annoying!! In the actual position I was also looking at the sac 80. Rxd6+ but eventually decided that White had to play 80. f4

I was right but didn't find all the defensive moves.

  Richard Taylor: When this game was played I was nearly or probably 1 years old...lol

I think this fact is very important in the significance of the game...

Jan-29-06  Fezzik: Rossolimo's play here reminds me that Grandmasters from the distant past (1949 in this case) broke ground in every phase of the game. This is a great example of how to create a weakness in a second part of the board when all the pieces are cramped. This is what is sometimes called a "positional" sacrifice. But as anyone who spent time on it knows, it relies on tactics to work.

  kevin86: Eight pawns for both sides through 66 moves!! This one looks a bit fishy,but the ending is fine! Could be a subject of a Monday puzzle (the two move mate-that is)

  Calli: Lots of pretty variations in the notes. Suppose Black tries 81...exf4 then 82.Qd3! threatens e5 and Qf5+ 82...Qf8 83.e5! anyway 83...fxe5 84.Qg6 the threat of Qe6+ wins

Jan-29-06  joeaverage: <psmith>Thanks much! This was a very difficult puzzle for me to understand.

  patzer2: Rossolimo's 80. f4!! is a strong positional clearance sacrifice, allowing White to regroup his Queen and Rooks for a decisive attack on the Black King.
Jan-30-06  RookFile: Rossolimo, for some reason, had some of the absolute prettiest combinations ever, in his games.
Jan-31-06  LIFE Master AJ: I must agree with <RookFile>, some of Rossolimo's combinations showed not just brilliancy, but UN-MATCHED artistry as well!
