«It is beyond my comprehension. After the second game of the match was virtually over. » Blockquote> 3 party. Kasparov - Deep Blue. ½: ½
Kasparov played white hard, but carefully.
Computer got cramped position, make foreign lurid passages, actually is irreproachable in terms of defense. Pomaia and not finding win (which was not), the world champion agreed to a draw.
4 party. Deep Blue - Kasparov. ½: ½
Kasparov again surprising choice for the debut of black - protection Pirc-Ufimtseva that, like, black color, he never played. On the whole, Harry managed to beat the machine, but the computer hard clung to every possibility and found all new resources to hold the position.
At some point, Kasparov played inaccurately and cyborg managed to wriggle out of the clutches of homo sapiens. If black instead of the exchange of queens to double the rooks on the half-open vertical «f» i> , white would have badly: their figures were really quite disorganized. The diagram winning position for Black, which could occur if the world champion went the right way. White has a pawn more, but their figures are worse than the other one. At that time, as black troops occupied the ideal position. But fortunately for Deep Blue and Kasparov unfortunately for this option is not held in reality.
5 Party. Kasparov - Deep Blue. ½: ½
Kasparov urgently needs to win - the score is still equal, and his last white. Again extraordinary "antipozitsionny" debut Reti. The computer has surprised on the 4th course, exchanging bishop for a knight. The fact that the then electronic chess gave undoubted preference ranged elephants, changing them to malopredskazumyh horses only when absolutely necessary. This strengthened suspicions Kasparov, what happened to him play fair. "I know something about chess and computers. This is not a computer game! "- He said after the game. Although this party so early exchange was appropriate, as it allowed the black quickly develop other figures.
In the acute end of white became the masters of the right side of the board and passed pawn «g» i> have given the green light. It seemed that Kasparov, now finally win and lead in the long run. Black its small but well-coordinated forces dropped in the last attack, who personally led the black king. The final position (in the diagram) very impressive - though White can now put the queen, but it will not help them. Small but friendly black and white squad announces autocrat perpetual check.
Miraculous rescue your computer in this game completely demoralized Kasparov. No wonder that last game was a disaster for him.
6th Party. Deep Blue - Kasparov. 1: 0
Kasparov again elect a completely atypical for themselves debut for black. This time he used protection Cockroach Caro-Kann. White Kasparov always happy thugs "karokanschikov" (Karpov included), but for the black this debut is not part of his repertoire.
This allows you to start to build a solid black, but a passive position. White space is given, they are given a lot of opportunities for tactical strikes, traps and victims (if black will play sloppy, then the very first moves may even shlopotat mat). Here is one such victim Kasparov and decided to provoke their electronic counterparts.
Harry just looked like a pawn 7. ... H7-h6 (in the diagram), driving spirited horse. The theory recommends donate dashing white horse, receiving in return a very dangerous attack. After that black is extremely difficult to hold the position, but, in principle, possible. If you still be able to fight off the onslaught of a barrage, then there is the opportunity to stay with an extra piece and eventually win. Apparently, with a cunning plan Kasparov still hoped to finish the match in their favor.
The computer receives a call and gives the horse to the slaughter - 8. Kg5: e6 8. ... Fd8-e7 , after which we can not escape (see. The following diagram).
Looks good on the surface, as it allows to hide the black king on the queenside. However, it turns out that there is much easier to attack. If the black king sought salvation in the opposite direction, then get to him would be difficult. In addition, the black queen violates the coordination of their own figures, in particular, does not provide promptly to bring an elephant from the field f8 i>
Deep Blue won with cruelty. On the 18th move black queen fell on the 19th person admitted defeat. While on board Kasparov still enough material to give up already at the time. Numerous black troops completely disoriented and interfere with each other. White calmly alternate mating attack with systematic devouring enemy pawns and pieces.
The final position of the party and the match. Stroke of black, but it is difficult to give good advice.
"This machine is nothing yet no one has proven!»
At the final press conference Kasparov thundered, alluding to the fact that did not play against the computer, against a bunch of "computer + GMs" that left him no chance.
What made the first and second batch of machines to do frankly weak moves, if obviously were much stronger alternative?
Why in the parties ended in a draw, the machine first played poorly, and then devilishly ingenious?
Where the operator removed the computer before making some moves in the 4th party?
What are the reasons for the 5th batch of computers so quickly parted with their favorite elephant is already on the 4th move?
In this connection, after the 5th batch printing of technical protocol was made so late?
As well in the 6th game computer, without hesitation, went to the knight sacrifice, because it (the theory) does not guarantee victory?
Why is it that at a critical moment in one of the parties, the operator started something very fast typing on the keyboard?
Why errors Deep Blue did not allow a very strong commercial chess program Fritz, when she was given to the analysis of the party of this match?
The last batch. Made with only a dozen moves, but the loss of black already inevitable. I>
Some time later, when several emotions have cooled, Kasparov has refrained from charges and offered to arrange another match. Champion complained that he did not have enough time to prepare for the competition. Also complained too intense schedule of games, which is irrelevant to the supercomputer, but heavy for a man. And 6 rounds - too short a distance and Harry offered to organize a new game, but with a greater number of parties (8 or 10). In this case, the prize was agreed on a formula "all or nothing", that is, in case of loss would not qualify for any money for their participation. And even offered to a contest with a supercomputer to wager the most precious - his title.
Harry seemed to many arguments persuasive and chess community believed that IBM owes humanity one more, this time decisive match. But the third round did not take place, primarily because of financial considerations. The victory over Kasparov brought the company huge image dividends, shares of the corporation increased in price. But if the computer will win in the next confrontation, then such a powerful public response will be gone. Won re-computer hardly be apprehended by the public as an extraordinary event. But the possibility of defeat, wiping out all the marketing gains from victory in the second match. Conducting again expensive exercise is not to promise more benefits, more than that - bore the risk of loss. Therefore, it was decided to let the Deep Blue is guaranteed and will be the winner Kasparov.
Kasparov took a very painful and humiliating defeat IBM refusal to play another game, even more so against the background of their own suspicion of plotting against him. The next time Harry agrees to fight with the robot after many years. This is - the next, the last story.
