Mar-09-15  Bycotron: Interesting how black constructs what looks like an extremely solid defense by placing the Knight on e5, defending f7, and the Bishop of f6, supporting the Knight and blocking the dangerous f-file.

Then in one move, Ng4, he moves the defending Knight offside and exchanges the critical Bishop! It is beautiful but not surprising that Rxf7 comes at the immediate punishment of his folly.

Mar-09-15  Strongest Force: Looks more like a blitz game...

Too bad the gov't chased JS out of the country.

I guess they both were chased out..

Mar-09-15  Moszkowski012273: IMHO blacks refusal to take early on e4 was the main reason why his game went downhill. Also, (I'm sure it's already been pointed out) Fischer missed the mating Bg8 several moves in a row at the end.

Okay. We're all agreed on that.

But the pun is not so good.

  ahmadov: Now what I do not fully understand is if Fischer could foresee all the moves from move 29 to the last one, or there was a share of luck in the outcome of the game?

  Petrosianic: You don't necessarily to foresee the game to the end to know that a move is the best one.

  ahmadov: <Petrosianic>, what you are saying is true as a general rule, but when I played through the moves I mentioned, I had an impression that he analysed all the possible lines before playing move 29.

That is probably it. Thanks! I thought it might have been a pun on "Sure Win Forced". But that would be a bit ...um...forced.>

...maybe: <"Sherwin's Forced"> to resign!

If one was to take you literally (which I hope no one does), there are 15 plies (one move by each side) from 28...Bxc3 to 36...1-0. If we estimate that there are, on the average, 3 reasonable (not possible, but <reasonable>) responses to each move by each side, that's 3^15 or 3,375 reasonable moves. I'm nowhere near to being a GM but I doubt that any GM could calculate and evaluate the positions after 3,375 moves, particularly in a reasonable amount of time.

If there were, on the average, 2 reasonable responses to each move by each side, that's "only" 225 reasonable moves. Maybe that's within the range of a good GM, but I doubt it. So if any good GMs are reading this, please correct me if you think otherwise.

Now, if someone (not me!) were to take you <truly> literally, they would like to know how many possible legal combinations of moves there are from 28...Bxc3 to 36...1-0. To find out I used the chess engine Hiarcs 14 which, although not the strongest of engines, has the capability to turn off search pruning entirely by setting its Selectivity parameter = 0. This forces it to look at <every> possible combination of legal moves from the starting position.

And, after 00:50:34 minutes of calculation, at d=15 Hiarcs had looked at 4,590,249,806 positions at an average rate of about 1,506 KNodes/sec. So I think it's safe to assume that Fischer didn't look at all the possible lines before playing 29.Bxc3.

And, BTW, Hiarcs evaluated the resulting position after 29.bxc3 assuming best play by both sides at [+0.28], effectively equal. So Sherwin's losing mistake must have come after 28...Bxc3.

Mar-17-16  cunctatorg: Jokes aside, this Sherwin guy can present to the chess world ... a win against Bobby Fischer and also one draw with him!! Not only remarkable but superb!!

He was lost before moving the knight. Black is about to lose his a pawn and white will have connected passers and the 2 bishops controlling the queenside.

  steinitzfan: A short move sequence from 30 to 33 but it makes my head spin.
Jul-05-17  avi20072008: I didnt get move 32? Can someone please explain? Why didn;t rook took Queen. It could have been checkmate.

Because 32...RxQ is discovered check with the bishop on d5.

  offramp: User: avi20072008, welcome to chessgames.com. I am sure you will have a good time here.

Moves 30 to 36 in this game are really worth examining closely. They are brilliant.

It's worth remembering that Fischer was 14 at the time.

Jul-24-17  newzild: Hmm. Didn't Fischer miss a forced mate?

It looks to me as though 34. Bg8+ mates.

Example lines:

34. Bg8+ Kh8
35. Bf7+ Kh7
36. Rh8+ Kxh8
37. Qc8+ Kh7
38. Qf5+ Kh8
38. Ra8+ and mate next

or:

34. Bg8+ Kg6
35. Bf7+ Kf6
36. Bxh5+ Ke7
37. Re8+ and mate next

What am I missing?

Jul-24-17  Howard: You're probably not missing anything--but, since the move Fischer actually played was good enough to wrap up the win, it probably didn't matter.
