| Jun-14-07 | | zev22407: 20)h4 the winning move! |
|
| Sep-27-07 | | crisP: what if 20...gxh4? |

| Dec-18-07 | | dazone3: Kasparov is bigger than Jesus! |

| May-16-08 | | apexin: 20...gxh4 21.Qh5 followed by Be4 |

| Oct-24-11 | | DrMAL: This lesser known Kasparov game is gem for learning technique. At transition of opening white has IDP and textbook position for active pieces whereas black pieces are quite passive. Critical square is d5 and probably plan is not to battle for it but instead exchange advantages by opening position via d5 and taking advantage of activity. Here is computer eval for reference.

+0.20 14.d5 exd5 15.Nxd5 Nxd5 16.Bxd5 Rc8
Kasparov plan is hybrid of these two and probably best, 15.Nxd7! Qxd7 16.d5! gets bishop pair advantage as well. Similarly, computer gives 18.Qxd5 Qxd5 19.Bxd5 slightly more advantage but Kasparov avoids Q swap, with probably best winning chances. 18...Rfd8 was most accurate but black chose "safer" 18...Bg5 to trade pieces. Not sure where Kasparov saw 20.h4! but it was probably here. In any event 19.Bxg5 hxg5 arrives at critical position. Computer lines here are interesting for discussion.

From diagram, obvious idea is to replace Q on d1 with R but Q must protect B on d5, if it moves Qb3 or Qf3 then Nd4 attacks Q. 20.h4! gxh4 sacs pawn for Qh5, getting Q out of way (actually onto great square for h-file attack) while still protecting B. Now notice of six computer plans above there is only one that avoids Q swap, 20.h4! this was totally brilliant, best move. Computer underestimates danger of Qh5! if computed over much longer time it would probably evaluate 20.h4! as clearly best. With white R soon on fourth rank h-file can become big problem for black. Nogueiras realized danger of this and chose original idea of Rfd8 but in this position (instead of move 18) it was probably not best. After 21.hxg5 white was up pawn and in sharp position 21...Qf5 instead of 21...g6 was small error according to engine. From here Kasparov played perfectly, after 23...Rb8?! white attack was decisive. 26...Re1+ instead of 26...Qb1+ made finish even easier, game had magnificent middlegame technique. |

| Oct-24-11 | | AnalyzeThis: Well, the opening is really the queen's gambit accepted, not declined, as chessgames incorrectly lists here. The d5 thrust is common, it's white's big idea in this opening. |
|
| Oct-24-11 | | DrMAL: <AnalyzeThis> Yes d5 is one basic idea among several, often battle is over control of d5 square instead, especially for black to occupy with N or B. In any event, point of post was to elaborate on transition to middlegame and plans/technique involved afterwards, this is most important area to improve (once beyond certain level) I hope post was some help, cheers. |

I checked Kasparov's analysis of the game in Informator (ref. 45/462). He certainly regarded 18...Bg5 as dubious. 18...Rfd8 he regarded as slightly better for white after <19. Be4! Qd1 19. Red1 Rd1 20. Rd1 Rd8 21. Rd8 Bd8  > His preference was <18...Bf6!> which he also analysed as slightly better for white but where black has good defensive resources. I agree about this game being nice. Garry was happy about his 20th move, which he gave two exclams. It says something about the pressure because Nogueiras's 23...Rb8 was a blunder in time trouble! 23...Re8 would have kept the game alive but white has a clear advantage after 24. Re8 Re8 25. Qc3! (Kasparov). |

| Oct-25-11 | | DrMAL: Thanx <SWT> for reference to Informator I do not have, wish I had your great collection! At time, this game (like all from both Kasparov and Karpov) was in newspaper where I remember commentary was something akin to game being won by one move (it has two exclams in my notes too). While 20.h4! was certainly best and totally brilliant move (hopefully now known to CG audience) Kasparov play throughout whole game was also totally brilliant, it is great example of his technique: consistency and accuracy with making threats and very carefully judged risk. Yes, I believe Nogueiras spent very long time on move 20, but I did not realize passive move 23...Rb8?! was in time trouble (not in notes, forgot, sure it was in news story) thanx for noting. In terms of saving game, notes also had 23...Nd4! threatening Q or 23...Ne7 threatening B but I do not take credit, they came from analyzing with teachers/others. It is great to have powerful engines today to look more carefully at moves and ideas from back then, here is Houdini eval showing various alternatives. Houdini_20_x64: 29/77 1:18:04 56,379,679,633

I was very fortunate last year - one way was nicely and another way sadly. Nicely - because I was offered cut price copies of the past 25 issues from a chess supplier Sadly - because the remaining 80 volumes were acquired after the death of a big chess book collector and local player. I'd like to think he would be happy the Informators went to an active chess player who shares some of the information they contain with others. |

A little pricy, but very valuable. |
