 | | keypusher: The gap between a current SF program available for free and the Greenblatt program is staggering. A few quick notes: after 8....Bd6? 9.d4, SF's evaluation is already about +1.5; as Fischer shows in the game, Black can't defend the gambit pawn. (What's Black supposed to play instead of ...Bd6? SF finds the ingenious 8.....f5, with the idea 9.Nxb4 fxe4, with ...Qd4+ winning the QN if the KN moves.) SF finds 10.Nxg5 instantly and rates white about +4 in a shallow search. The engine briefly prefers 12.Nxf4 but quickly decides that Fischer's 12.Rf2 is better.
The Greenblatt program presumably calculated that 16....Be6 17.Bh6 Qg6 18.Qxg6 and Bxf8 lost a rook but (understandably) didn't realize that 16....Rd8 17.Qxh3 was even worse for Black. I think the only move by Fischer that could conceivably be called a mistake is 19.Rc1. 19.Rg3 is actually a forced mate after 19....Qxc2 20.Qh6 Rd1+ 21.Rxd1 Qxd1+ 22.Kf2 Qc2+ 23.Bd2 Qf5+ 24.Ke1 Qxe5+ 25.Kd1. But of course 19.Rc1 is crushing, leaving the queen with no escape, and a sensible move for a human to play. As several have noted, it's odd that the 1977 engine allowed mate in one. 20....h5 is mate in 8, but I wouldn't expect the Greenblatt program to be able to work that out. |

 | | MissScarlett: I've little doubt there is much more to be uncovered about many aspects of Fischer's life, but <Joshka> seems utterly oblivious to the amount of work and money that such researches entail. Most of the new material that's come to light in recent years has been due to the publication of rare and expensive books,<Bobby Fischer Uncensored>, <In Memorian> and <Bobby Fischer: Triumph and Despair> culled from the David DeLucia collection. I'm pretty sure that <Joshka> has his grubby hands on one or more of these books. But has he gone to the time and trouble of sharing any of this new material with us? |

Do you remember your first computer chess machine or program? I think mine was the <Saitek Crap> c.1982. |

Funny I was thinking about my mum and dad buying me a chess computer for Xmas as a kid just the other day ... Straight up. Botvinnik pioneered this schiit... what a fkn MONSTER was created.... Now we have two bit patzters opening up their own YT accounts blogging on Bobby's games offering improvements Yaaaaahdi Yaaaaaaahdi Yaaaaaaah ect ect using fkn ENGINES ... Engines which HAVE STILL TO COME TO TERMS WITH FISCHER'S STYLE ... lol lol |

| | keypusher: <MissScarlett: <Hazz>, here's the original (CC1) <Fidelity Chess Challenger> that Bobby was duking it out with instead of Karpov:> I had that! Only clear memory is once it had its queen on d7 and king on e8, with the e-pawn not having moved yet. I found Bxf7+ and Ne5+ winning the queen. I was as proud as if I'd won the Immortal Game. One big problem old engines and patzers of all ages have is not really understanding the openings they memorize. I assume the Greenblatt program was playing "book" up through 6....0-0. But then it's on its own, and plays two second-rate moves in a row, ...Nxd5 and ...Bd6, at which point it's already pretty much lost. Neither one of those moves is visibly awful, though, and I can see a decent but underprepared human player making them. At at that point, after 9.d4, you either give back the pawn and concede your opponent a powerful pawn center + the f-file, or try to hang on to the pawn. If you're human and you know you're playing Bobby Fischer, you probably do the former; if you're a computer and don't even know you're playing chess, you pick ...g7-g5. In short, those of us below master strength shouldn't be too sniffy about the way the Greenblatt program played. |

<<piroflip> Bobby take this machine apart for sure but I remember reading in a chess mag's report on this game that it had a rating of 185BCF. This equates to almost 2100!!> Highly doubtful.>
From the chessgames GreenBlatt page:
<it acheived a USCF rating of 1243 in 1966> Of course we don't know who it played after that, and if any improvements were made. <No, 1200 baud modems were introduced in 1972> Did they have modems where the phone line plugs in like today? I only remember Ken Thomson using
"acoustic" modems.
(Id imagine a direct connection was more reliable vs "listening" and "speaking" your signals audibly) Ken also had the first board I saw
that lit up the square of the piece you move and where it was going. It was about 4 inches off the table to
accommodate the electronics. The pieces
were normal wooden pcs. However, if you looked on the bottom, the felt was off,
the wood was gouged out, and crystals were epoxied in. When the board was scanned with Rf, the resonate frequency
of the crystals told Belle what the position on the board was. <Also see my "analysis" of the remote move transmission: Geller vs Fischer, 1965> I played on the National Chess League.
(Telephone) There were 4 Boards, each board had a "runner" who would play the verbally transmitted move on your board(your response would be taken by your runner for verbal transmission to their runner). I've heard it said Fischer was
handicapped due to longer/slower games.
From my standpoint, that was more than made up for by more time on the clock.
We were updated on times every 10 moves. There were 20/40 minute periods where I actually used 2 mins on my clock. Since Fischer was one of the fastest players in the world, the time lag probably helped his opponents more. With Fischer, you also needed to redefine "transmission error." I've heard the story he had the move:
1.d4, he responded 1...Nf6, white's
response was 2.e5. Indicating d4 was wrong and e4 was actually the first move. When Fischer was told he could replay it, he just played what was on the board. Basically playing an unprepared Alekhine's Defense. |

| | MissScarlett: At least, it appears that <Chess Challenger> recognised promotions. I heard of one program that didn't - the promoted pawn just hovered on the 8th rank in perpetual limbo. |
|
| Oct-13-18 | | RookFile: I remember that some of the old programs couldn't mate with king and rook against king, as long as you kept making your moves quickly. |

 | | thegoodanarchist: < RookFile: I remember that some of the old programs couldn't mate with king and rook against king, as long as you kept making your moves quickly.> Were those "stand alone" chess computers with an actual board? I remember when those were the most popular chess computer options, and at one point a company advertised their machine by saying it was capable of checkmating with knight + bishop :) |
|

| | thegoodanarchist: 13...c6 is definitely a "class player" type of move. By saying this I mean someone rated <2000 USCF. This is a move by a player who (which) thinks he (it) has the initiative. Um, sorry, no you don't! |

 | | AylerKupp: <RookFile> My second favorite story about those early computers and their "playing ability" was a game that was published in either Chess Life or Chess Review in the mid to late 1960s. The computer, playing White, had a Pc2 and a Nc3. In response to Black's previous (and very threatening move) it played c2-c4 (!) blocking the threat. While it clearly knew that pawns could advance 2 squares on their first move, it didn't know that they could not jump over pieces! The commentators said something along those lines and indicated that c2-c4 was extremely convenient and that the arbiter, so to speak, let the move stand. Needless to say, with that kind of demonstrated "playing ability", Black won easily. |

| | AylerKupp: <<thegoodanarchist> This [13...c6] is a move by a player who (which) thinks he (it) has the initiative.> You mean something like 14...Nxc4 in Portisch vs Tal, 1964? See my comment there in Portisch vs Tal, 1964 (kibitz #27). |

I think he is talking about Greenblatt who after this game went onto claim that Humans had fixed World Chess. |

 | | Diademas: Could be a Monday puzzle.
20...? Black to find the only move that allows mate in one. |

| Oct-14-18 | | AlicesKnight: <MissScarlett, Keypusher et al> I still have my Chess Challenger, in working order. From those distant days.... I regard it with some affection. It was handy when multi-tasking on some long, complicated and uninteresting work-at-home stuff - to glance at the CC for a few seconds and make a response was light relief when on about level 5 or 6 (not 1 or 2 when I agree it played help-mate at times). <MissScarlett> Thanks for the Youtube clip; my version came in a smart plastic briefcase, and has the correct algebraic marking, so perhaps I have a 'second edition'. The little lights on the display flick slowly back and forth as if to say "I'm alive and thinking....", unlike some silicon - cute..... |

Thanks for setting me straight! And I also missed that in the past he had referred to Fischer as "the computer". Thirty lashes with a wet tablebase! |
