Bobby answers from beyond the grave:
12. Ng5 Notice [stacase], how Ken slowly builds up his position. Before he takes any decisive action, he moves all his pieces out to their most active posts

Dec-30-16  The Kings Domain: Tough, deep puzzle and great game.
Dec-30-16  varishnakov: First thing that suggests itself is a knight sac at f7. And the natural move is a recapture of the pawn with the rook, and the threat of a discovered check. But black has a defensive move that seems to hold the position.

I spotted pretty quickly that white's LSB and Re1 both converge on Pe6, which is supported only by Pf7, which in turn is supported only by black's king. Furthermore, my Ne5 is blocking my rook and attacking that Pf7. Naturally, the move that jumps out is <18.Nxf7>, undermining the now doubly attacked Pe6.

Starting with the (unclear) assumption that black takes the knight via <18...Kxf7>, we are now in position to take Pe6. But with which piece?

My first inclination (based just on experience) that its often stronger to take with the piece that doesn't give check (the rook in this case). This opens the door for further tactics like discovered check (e.g. windmill) or double check. So, trying <19.Rxe6>:

And this does indeed produce some juicy threats:

- If the K remains on f7 and the N remains on f6, then Rxf6++ (double-check) wins back the piece to go with the 2 pawns, with further attack to come.

- If the 19...Kf8 (unpinning), then the Nf6 loses a defender, thus Bxf6 wins.

So black needs to consider knight moves:

- If <19...Ne5> blocking my LSB,

This took a moment, but white can undermine the N with <20.Rxc6! Rxc6 21.Bxe5+> winning back both the N and R (plus another pawn).

- If <19...Nd7> then Re7+ and Rxd7 next.

- If <19...Ne8> then 20.Re5+ Kf8 21.Be7#

- If <19...Ng8> This is another "thinker", but the forcing moves aren't too hard to find: <20.Re7+ Kf8 21.Rf7+ Ke8>

click for larger view

I was stuck here for a moment until I remembered that I had another rook! <22.Re1+!> with just some futile blocks until mate.

- If <19...Nh5> then 20.g4 and the N has nowhere to go.

- If <19...Ng4> (stupid) then 20.hxg4.

- If <19...Nd4> (also stupid) 20.Rxe4+.

Now, if black doesn't take the N, I don't think he actually avoids trouble because I still have Rxe6!. Guarding e6 (18...Re8) is pointless since it's double attacked. I think I should be happy.

Dec-30-16  JASAHA: There is a discrepancy in the move order compared to Fischer's analysis "That alone makes Fischer's notes worthy of study. Already after the initial moves 1.e4 g6 2.d4 Bg7, I learned something new.

Fischer: The Pirc defense, also called the 'Rubbish' or 'Rat' defense because of the cramped but fighting game it gives Black. The game continued 3.Nc3 c6 4.Nf3. Here Fischer gave a relatively detailed analysis of the alternative 4.Bc4. Why spend this effort on the fourth move? Due to Black's having avoided ...Nf6, the game has already branched off into less charted territory, which Fischer obviously thought was important. After the further 4...d5 5.h3, White's fifth is the sort of move that sometimes gets a '?'. Fischer gave it a '!'."

Dec-30-16  SpamIAm: Faster than 20.Rf6+ as in the game was 20.Re5+(or Re4/Re3/Re2/Re1)Kf8 21.Be7++. But I think everyone already realizes this, though no one has actually posted the moves.
Dec-30-16  Capacorn: <Abdooss: shows Fischer's analysis of this game here --- < >>

Thank you for posting this link, Abdooss. I'd read about Bobby's "Boy's Life" columns, but never actually saw one myself. It was great to read Fischer's notes. He had a real knack for shedding light on the game. Such a pity he wrote so little on chess. Directly after enjoying your link, I checked to see if an English language version of Gardar Sverrisson's "Bobby Fischer's Final Years" had been printed. It has not. But as luck would have it, I stumbled upon "Checkmate: Bobby Fischer's Boys' Life Columns," which I immediately ordered. The book was only published last month, so it's rather serendipitous that I happened upon this puzzle, and your link, when I did.

  FSR: Pulling the Rogoff from Under Him.
Jan-03-22  Caissanist: I'm inclined to doubt that Fischer actually wrote much of his Boys' Life columns. Larry Evans has acknowledged that he would "help him out" with them and the tone and writing style didn't change at all when Evans took over the column under his own name.
Jan-11-22  jerseybob: <Abdooss: shows Fischer's analysis of this game here> Nice annotations by Bobby, and a nice personal anecdote about him visiting the U.S. Junior, but the game is given there in a Pirc move order(i.e.1.e4,g6 etc. and it transposes to the Gurgenidze) I tend to believe the Boys Life version, so why does change the move order around?
Premium Chessgames Member
  perfidious: <jerseybob>, the one time Spencer and I met, as I mentioned at his player page, it began as a Modern, with 1.e4 g6 2.d4 Bg7. Still do not recall the rest of the game.

  FSR: I tried to substitute <Better Call Saul> as a pun for this game, but someone beat me to it - whether for this or a different game, I don't know.

  Fusilli: <FSR: I tried to substitute <Better Call Saul> as a pun for this game>

Why? I don't get it. I am currently watching that show. What am I missing? If it's something about the finale, please don't spoil it for me! I just started season 5.

Premium Chessgames Member
  FSR: <Fusilli> Most of my puns aren't very deep, as some critics have noted. (A few, like my proposed "The Bridge Stripped Bare By His Batchelor" for N Bridge vs P J Batchelor, 2016, are slightly more sophisticated.) That one is simply based on Rogoff's middle name being Saul. I've never seen the show. My wife (a retired nursing professor and cardiac nurse) and I are currently watching "Grey's Anatomy" from the beginning.

There's a really long-term project!

I watched all of Seinfeld between sometime last year and earlier this year. I had never seen it before.

  DaltriDiluvi: It always annoys me a little when a player only has 1 legal move and he resigns instead of playing the move.

Premium Chessgames Member
  FSR: <stone free or die> If it were solely up to me, I'd seriously binge-watch, like all night if I didn't have to work the next day. I can't get my wife to watch more than two or three at a time. We're up to Season Six, Episode Three.
