Dec 28, 1995 Romania and Chess (Adrian German, Ariel Mazzarelli) May 7, 1997 Kasparov vs Deep Blue (Ariel Mazzarelli, Eric Wang, et al) =============================================== Subject: England '96 preview: the Romanian team. From: "Adrian German"Date: Dec 28, 1995 It's been often said that a European Championship lacks some of the glamour of a World Cup Tournament, since the South American teams are not coming. England 1996 is certainly no exception, but there is an amendment: from the eastern part of the continent Croatia, Bulgaria, and Romania will be carrying to the games a very distinct spirit, and style of play. ROMANIA It is impossible to make justice to the history of the Romanian soccer in such a short space and knowing that, we will simply not deal with it here. In doing so we are leaving out a large and significant part of the athletic phenomenon, together with its social connotations. But we have no choice, and we will be well justified, and our time well spent, if we concentrate on the present. The 16 teams for England '96 will start the competition on the 8th of June 1996 with a clear purpose: they are playing for the European crown. There is clearly no other good reason for taking part to a final tournament if you are not going there to actually win it. As such the Romanian team will fly to England in 1996 with a visible goal in mind: to win the continental title. 1. Preliminary Round Romania qualified atop Group 1, ahead of France, Slovakia, Poland, Israel, and Azerbaijan. Romania - Azerbaijan (3-0) was the first game in Bucharest since the lost shoot-out in San Francisco (Petrescu and Belodedici). The game saw a beautiful goal from Romanian sweeper Miodrag Belodedici, and the Romanian team never left the Group's first place after that game. It is the great merit of the Romanian coach, Anghel Iordanescu, to have read attentively all the fine print of these preliminaries. His team, that had given its share in two of the most spectacular games in the USA '94, against Colombia and Argentina, did not however put on an impressive show during the group's matches. Nonetheless, Romania drew only three games away (Israel 1-1, France and Poland, both 0-0) lost a game at home (which sealed the qualification for the team of France) and quietly won the rest of the games. 2. Anghel Iordanescu, and the Romanian style of play Anghel Iordanescu was a gifted player. He started on the left wing, and finished his career (in Sevilla, May 7th 1986) as a playmaker, in the middle. His coaching career (started around 1984, when he came back from Greece) saw him at Steaua (1984-1990), in Cyprus (1990-1992, Anorthosis I think), at Steaua again and then at the national team. For the reader who has seen the game against Sweden and has been left hanging waiting for a second round of display Hagi-Dumitrescu, Iordanescu requires a word of explanation. The pace of the game against Sweden was a deliberate, although unfortunate move. This important aspect helps us make the distinction between the past and the present. Against Argentina and (especially) Colombia, Iordanescu played like the chess grandmaster - World Champion during 1894-1921 - Emanuel Lasker sometimes used to: by constantly introducing unnecessary complications into the game. The purpose being to generate significant overhead in an opponent who's trying to make sense of your game, the strategy sometimes pays off. But combine this with the lessons that an attentive observer could have learned from the second Bearzot (1982) and you get all the ingredients of a rather strenuous game -- for player and spectator alike. What Iordanescu knew, but had magnanimously been overlooked by others at large (teams and coaches alike), was that given the chance during the game he could fall back on one trump: this was the gift of the swift and classy touch out of which the spectacular Rose Bowl fireworks displays of Raducioiu, Hagi, and Dumitrescu have been created. For Iordanescu and his team this strategy was a way of concealing a certain lack of confidence. It is the conviction of this writer that the preliminaries for England have bridged the transition from a skilled, but often unfocused, and shy Romanian team, to a team that can motivate itself to the utmost. And since these lines are written when we're still in 1995, we will leave it to the seasons between now and then to prove us right or wrong.

Date: Dec 30, 1995 Fine, let's assume it's as you said. First some background. "Lasker took 3rd place behind Pillsbury and Tchigorin at Hastings 1895. He almost died before this event and was still recovering from typhoid fever." (from http://www.datashopper.dk/~mathis/lasker.html courtesy Palle Mathiasen) Now the facts: [...] "During the war, Lasker had invested his life savings in German war bonds and lost it all. He tried to breed pigeons, but all the pigeons he bought were male." Such a great player with so little (should I say) common sense. I bet Steinitz wouldn't have made this mistake. "After the war he won a strong tournament in Berlin in 1918. [...]" Yet he recovered gracefully. Amazing. You were right. Lasker _was_ Italia. Capabalanca was Argentina, and Romania... Romania was Alekhine. --------------------------------------------- From: mazzare@primenet.com (Ariel Mazzarelli) Subject: Re: England '96 preview: the Romanian team. Date: Dec 30, 1995 Should we split the group with rss.chess? Anyway, > "Lasker took 3rd place behind Pillsbury and Tchigorin at Hastings 1895. Before that tournament he gave some lectures in London that became a book, Common Sense in Chess. It is now a $5 Dover, and it is really cool. He analyzes other games against Steinitz as examples of general principles--and his analysis is often an addition to what you find in, say, ECO. > [Steinitz wouldn't buy all male pigeons or lose his savings] It is hard to say, Steinitz never had a whole lot of savings to lose. Of course it is very unlucky, money-wise, to be hit with a World War 1.0. > Romania was Alekhine. You think Romania's tactics are that good? Could be. Romania has not won a big cup yet, though. You're right about Argentina, I'd add that Argentina '86 was like Tal '60. Brasil is clearly Botvinnik, Germany is probably Alekhine, Uruguay is Fischer, England is Staunton, and nobody touches Karpov or Kasparov. I know that this is a ridiculous thread, but it has a certain logic. ============================================= From: mazzare@primenet.com (Ariel Mazzarelli) Subject: Kasparov is no Diego Date: 7 May 1997 02:35:02 -0700 First, from Reuter ====== Tuesday May 6 11:35 PM EDT Kasparov in Awe of Chess-Playing Computer NEW YORK (Reuter) - World chess champion Garry Kasparov has called supercomputer Deep Blue an "alien opponent" but Tuesday he said it was playing like a god. The best player in the history of the ancient game has suffered the double embarrassment of needlessly resigning to the IBM system on Sunday and then being held to a draw in Tuesday's third game of their six-game re-match despite the advantage of the white pieces. "The scientists are saying that Deep Blue is only calculating, but it has showed signs of intelligence," said Kasparov, who had no advance information on his opponent and has labeled it alien. The $1.1 million match is tied at 1 1/2 points each and Kasparov will have to play with the black pieces in two out of the three remaining games. One point is awarded for a win and a 1/2 point for a draw. Playing with white has the advantage of the first move, much like holding serve in tennis. The revelation that the Russian gave up on Sunday in what was in fact a drawn position, dominated and overshadowed the third game of the contest, a closely fought draw out of an English Opening that ended with Deep Blue's programmers accepting Kasparov's draw offer after almost 4 1/2 hours at the board. "It reminds me of the famous goal that Maradona scored against England in 86. He said it was 'the hand of God'," stated Kasparov, referring to a goal one of the world's greatest soccer players, Diego Maradona of Argentina, scored in the 1986 World Cup in Mexico. Maradona illegally used his hand to punch the ball into the net but the infraction was not spotted by the referee and the goal counted. "Suddenly you know it played like a god for one particular moment (in the second game)," an animated Kasparov told hundreds of spectators after Tuesday's game. It was unclear whether he was accusing the IBM team of cheating or just awed by the computer's performance. The Russian's remarkable and rare oversight was a reminder to human players that their emotions can be a handicap in clashes with machines. Several leading grandmasters admitted that they too had initially missed the continuation that would have saved the day for Kasparov. It was left to an untitled player in an Internet chat room to claim the credit for unlocking the problem. Deep Blue's programmers also said it had not calculated the moves correctly during the game, something Kasparov described as "very human from my point of view." Grandmasters intensely debated how the strongest player in chess history overlooked a sequence of moves that would have forced a draw Sunday and maintained his lead in the match. Instead, the 34-year-old Russian resigned the position after Deep Blue's 45th move and the match was tied at one win each. Kasparov defeated the machine Saturday in the first game. Chess experts, almost without exception described Sunday's game as the best performance ever by a computer, likening it to the style of top human players. Kasparov was forced by Deep Blue to defend with his black pieces for almost four hours and looked tired and demoralized. "The computer has an advantage, it does not have this body of emotions. We humans get depressed," grandmaster Yasser Seirawan of the United States said. "The computer doesn't get depressed." Subsequent analysis showed that Kasparov could have played a series of moves to force what is known in chess as "perpetual check" -- one player repeatedly attacking his opponent's king, ensuring none of his other pieces can make further moves and thus a draw is the only outcome. The analysis began within hours of the game ending in "chat rooms" run by the Internet Chess Club. Surprisingly, it was an untitled player who first suggested the drawing sequence, according to Internet Chess Club director Gregory Belmont. === Now that I've taken a look at it, the draw is pretty straightforward once you decide to look for it.

If you've ever done any programming, you have a pretty good idea that there is a bug somewhere, particularly in something as complex as Deep Blue. Furthermore, Deep Blue only looks ahead fifteen moves (about fourteen more than I can), so it had no way of noticing that possibility of the perpetual check, no? I wouldn't be surprised if Deep Blue choked. In fact, the NYTimes article, suggested that Kasparov's real error was in assuming that a perpetual check was something that Deep Blue would automatically prevent, when in fact it didn't. Perhaps if Kasparov had been thinking that Deep Blue could choke he have had his draw..... --------------------------------- Subject: Re: Kasparov is no Diego Date: 7 May 1997 13:04:20 -0400 From: cpearson@freenet.columbus.oh.us (Chuck Pearson) : Neither do I, but I don't know about Deep Blue not choking.

If it had such a serious bug, it would probably have been located already. Also, most chess simulations use programming techniques that allow the computer to "learn" from its initial mistakes and thus generate its own parameters for the game engine to evaluatuate configurations. Again, it is doubtful that a bug as impottant as the one you are postulating would have survive. >Deep Blue only looks ahead fifteen moves [...] Since in a situation of perpetual check the configuration of the board repeats itself after one or two moves, the computer should have no difficulty detecting one if it has a look-ahead of fifteen. That's if the programmers remembered to implement a detection scheme, of course. -------------------------------- Subject: Re: Kasparov is no Diego Date: 8 May 1997 09:39:51 GMT From: wang-cs@ehsn7.cen.uiuc.edu (Eric Wang) Reuter writes: >"It reminds me of the famous goal that Maradona scored against England in >86. He said it was 'the hand of God'," stated Kasparov [...] This was in reference to Deep Blue's 37th move Be4, when it had 37.Qb6 available. Qb6 forked an undefended Bishop and Pawn, and Kasparov couldn't have saved both, so it appeared to win material, and thus the game. In the press room, nearly all of the 20 or so chess grandmasters polled said they would have played 37.Qb6; several of them, and Kasparov himself when later asked about the position, said they would have played it "instantly, without hesitation". However, Deep Blue's analysis during the game revealed that Kasparov could have met this move with a tricky two-pawn sacrifice, conceding material to free his pieces and obtain dangerous counterplay, and Kasparov did, in fact, have this sacrifice worked out and ready to go. DB's actual move 37.Be4 was *materially* worse, since it won no material, but *positionally* better, since it strangled Kasparov's position and slammed the door shut on his only glimmer of a chance at counterplay. It was this positional awareness to play like an "anaconda" that has been computers' traditional weakness, and obviously many human experts lacked the foresight to see this move, too. This is what had Kasparov babbling and bubbling -- probably he hadn't seen a move of such depth played against him since his last loss to Karpov. BTW, Reuters are a bunch of dummies; Kasparov's words were meant in awe and tribute, not to imply cheating. The scuttlebutt is the other way around: the conspiracists are suggesting that it's Kasparov who's deliberately playing less than his best to make DB look good and guarantee another lucrative rematch next year (and the year after, and ...) IMHO, that's a bunch of hooey. >Several leading grandmasters admitted that they too had initially missed >the continuation that would have saved the day for Kasparov. It was left >to an untitled player in an Internet chat room to claim the credit for >unlocking the problem. Yup. Probably 50 grandmasters in attendance, and every one of them thought Kasparov was kaput. But this "mass hypnotism" was probably the result of their collective awe in watching undoubtedly one of the greatest, if not *the* greatest, games ever played by a computer -- playing the positional style that computers are usually very bad with, and playing it better than most humans could have. Kasparov himself was thoroughly demoralized by the end, and couldn't bring himself to believe that the computer had missed anything. (In fact, Deep Blue *had* missed the critical drawing line, which is evidence for its depth and subtlety.) >[match details] 44. Kf1 This was Deep Blue's mistake; at first, it didn't see the draw either. 44. Kh1, running into the corner, would have deprived Black's queen of the necessary first check later on, and thus sealed the win for White. >44 ... Rb8 45.

Re8! is the only move that saves the draw. Otherwise, White wins with the in-between move 47. Qc7+ Kg8, and now captures the Rook _with check_, 48. Qxb8+ Kh7, after which White's own Rook can drop back to help the defense, 49. Ra1, and now Black's queen cannot go to the first row to deliver check, so White's King eventually escapes. The position turned out to be extremely difficult, requiring more than 10 hours of analysis by Kasparov's seconds before they felt confident enough to break the news to him. Computer analysis remains incomplete to this moment, but after some 36 hours of calculation, every line of play has been plotted out to move 60 or beyond, and Black draws every one of them. After 46 ... Re8, the best line is 47. h4! hanging the Bishop, 47 ... h5!! declining the material to deprive the King of a critical flight square, 48. Bf3, and Black has a laborious series of checks that White cannot escape, and that eventually force three repetitions of the same position. ===================================== Date: Sun, 11 May 1997 18:07:22 -0700 From: Ariel Mazzarelli Subject: corposilicon wins Using a non-book sac in the opening (brought to ibm courtesy of some $100/hour grandmaster, perhaps?), the machine beat Kasparov in the last game and took the thing 3.5 - 2.5. Serves Kasparov right for resigning that drawn game, I suppose. Maybe it's time for a player that knows how to play these things to step up to the board. The move that took folks by surprise (although not if white had been Tal, of course) was 8.Nxe6. A very good positional sacrifice, and Kasparov probably defecated on himself at that point and it was over pretty quickly. Maybe 11...b5 was reckless; I'm looking at the variations starting with 11... b6 followed by a5 and Ba6 as possibly better defenses, although this allows 12.c4 which keeps the black knight from going to d5. One thing is clear, though--after 12. a4 black's king won't be much safer on the queenside either. After 19.c4 black resigns because he is just deep fried. 19...bxc4 20.Qxc4 and black loses at least the c6 bishop without fixing his position--eg 20... Nb8 21.Bxb8 Rxb8 22.Qxc6+ Nc7 23.Rxa7 Bd8 24.Ne5 is just sick--eg 24... Rxb2 25.Qd7+ Kb8 26.Nc6 mate. btw what happens after 19.c4 dxc4 20.qxc4 nb4? I like white, of course, but I don't quite get the 'oh yeah' move. 21.ra4 nb6 22.qe6+ kd8 23.Bc7+ kxc7 24.qxe7+ kc8 25.Rxb4 is the best I can do, and black is certainly ugly, but... well, I guess Garry was a little tired and just wanted to go home.
