|Mar-18-05|| ||Marco65: <patzer2> I didn't see your Fritz's analysis yet when I posted. Evidently GMs (and Fritz) correctly evaluate that 2 pawns + other positional advantages are better than a piece vs a pawn.|
Still, from a practical standpoint, lines like 14...Kh8 or 14...Qb6 should give better chances against a human rather than lines where you lose a piece in a very simple and forced way.
|Mar-18-05|| ||Marco65: <YouRang> Thanks for the link to the Endgame Study, I didn't know those weekly puzzles. At least I could solve something today! |
|Mar-18-05|| ||patzer2: Of course it depends on the position, but, IMHO, two extra pawns with the initiative is, more often than not, more of an advantage than an extra piece. |
|Mar-18-05|| ||dzanone: Amazing! Karpov losing in 18 moves. He has lost less than 10% of his games. That must be his shortest losing game. Gives a patzer like me some solace. |
|Mar-18-05|| ||hintza: <dzanone> Unfortunately Karpov has actually lost a shorter game that this: Christiansen vs Karpov, 1993! A tragic but somewhat comical game. |
|Mar-18-05|| ||patzer2: <Marco65> After 14...h6 15.dxe6 Qc7 16.exf7+ Kh7 17.Bh4 Bc5 18. a3 <Nc6>, play could continue 19. Qc2+! Kh8 20. Bxf6 gxf6 21. Qg6 Qf5 22. Bc2 f5 23. Bxf5 with a clearly decisive White advantage. |
|Mar-18-05|| ||minimaxing: <kevin86> Your variation is winning for white after 16. Ne5. |
|Mar-18-05|| ||soberknight: <YouRang> I was surprised by it also. I still don't understand it. |
|Mar-18-05|| ||patzer2: <Kevin86> <minimaxing> If 14.Bxe6? then Black secures the advantage after 14...Bxf3! (but not 14...fxe6? 15.Qxe6+ Rf7 16.Ne5! when White wins as you noted minimaxing) 15.gxf3 fxe6 16.Qxe6+ Rf7! . |
|Mar-18-05|| ||YouRang: <soberknight> (Referring to the ChessCafe endgame study #425) <I was surprised by it also. I still don't understand it.>|
White's threat is to approach the black king with the white king to force checkmate with the rook. To avoid this, the black king needs somewhere to go. He can't move his rook because then white's Ra8+ skewer wins the black rook.
The move black needs to make is f5! This makes room for the rook to move to f6, which prevents the approach of the white king, and gives the black king the important safe square on f7 where he can also guard his rook.
But Bf5! spoils it! After gxf5, black's pawns can't get out of the way fast enough. Black's king must either be mated or skewered by the white rook! (And if black tries f6 instead of gxf5, then Be6, which still seals off the key f7 square!
I love positions like this that look simple, but have a devilishly clever solution.
|Mar-18-05|| ||Saruman: <chessgames.com> I am quite sure that the location of this game was Skelleftå. However the year is correct I believe. |
|Mar-18-05|| ||patzer2: By playing the solid developing and defensive move 13...Re8!, instead of <13...Nb4?,> Black could have held the position and would have avoided losing immediately after <13...Nb4? 14. d5!> |
Play might have continued 13...Re8! 14.d5 Nxd5 15.Bxd5 exd5 16.Rxd5 Qc8 17.Bxe7 Rxe7 18.Qd1 Rxe1+ 19.Nxe1 Qe8=
|Mar-18-05|| ||vonKrolock: <Gypsy> Thanks! That game whith 13...Nd5 is very valuable - Suetin, in "Grosmeister Boleslavsky", Moscow, Ed. 'Fizkultura i Sport' 1981, focuses on another alternative, 13...Re8, that parries d4-d5, and gives <14.Ne5 Ne5 (not 14...Nd4 15.Qe3 Bc5 16.Qh3) 15.de Nd7 (Or 15...Nd5 16.Be7 Re7 17.Ne4 Qc7 18.Bd5! followed by 19.Nf6!) 16.Bf4 Qc7 17.Bc2 Nf8 18.Ne4, whith perspectives of attack> Of course he comments also that 13...Nb4 is weak, and so far two Soviet (sorry Russian) Chess authorities points out emphatically this... Karpov slept and was caught in what is already a recognized Opening trap |
|Mar-18-05|| ||csmath: This is of course in retrospect now. The position is critical at move 7. There today 7. ... b5 would be played and black would have sufficient defensive resources.|
By the way Andersson's record against Karpov is horrendeous so this win must have made him quite happy.
|Mar-19-05|| ||patzer2: <VonKrolock> Although 13...Re8!? is probably Black's best chance, and certainly better than 13. Nb4?, I've got to admit 13....Re8!? 14. Ne5! in Suetin's analysis gives White a dangerous initiative. After 13...Re8!? 14. Ne5!, Fritz 8 recommends 14...Nxd4!?, with play possibly continuing 15.Qe3 Bc5 16.Qf4 Rc8 17.Rd3 b4 18.Ne2 Be4 19.Rxd4 Bxd4 20.Nxd4 Qxd4 21.Bxf6 gxf6 22.Nf3 Qxb2 23.Qxe4 Qc3 24.h3 =, with an unbalanced but roughly equal position. |
|Mar-19-05|| ||vonKrolock: <patzer2> But if, after 14.Ne5 Nd4 is safe for Black, so is the 13...Re8 line too, inst?! - Nice You bother to bother Herr Fritz whith this bagatelle... |
|Mar-19-05|| ||patzer2: <vonKrolock> I'm not sure I put a lot of confidence in the 13...Re8!? 14. Ne5! Nxd4!? line, despite Fritz 8's optimistic assessment of equality. Playing into a deliberate pin is not my idea of fun in defending a position, and I prefer White's position here. Yet this odd line beats 13. Nb4? and just might give Black some hope of holding the draw. |
|Mar-19-05|| ||vonKrolock: <patzer2> All right, 13...Re8 is better than Nb4 or Na5 - Suetin's 14.Ne5 threat Nf7 seems to be the best attempt to take advantage of white's plus in development, but <a dangerous initiative> is not a forced win, so the whole thing until white's 13th move is still something playable, black's conductor having a choice between 13...Nd5 or 13...Re8 |
|Mar-19-05|| ||soberknight: <YouRang> Thanks for the commentary. After I posted, I took out my chessboard and discovered the same thing. It's a truly remarkable study. |
|Jun-30-05|| ||notyetagm: Amazing game. Karpov misses 14 d5!!, exploiting the <pin down e-file>, and goes under in a mere 18 moves.|
|Jul-01-05|| ||Kangaroo: Strange enough that Karpov forgot the well known game Boleslavsky vs Kotov, 1953 - he should have been aware of this opening and of the game itself!|
|Aug-24-08|| ||Katu: Nice to see Karpov made a blunder in the opening:)|
|Nov-03-08|| ||KingG: It's amazing how often Karpov has overlooked the typical d4-d5 break in IQP positions. Two other famous examples are Smyslov vs Karpov, 1971 and Portisch vs Karpov, 1975.|
|Nov-03-08|| ||AnalyzeThis: It's real easy to do. I've tried the QGA a few times against Fritz, and have gotten murdered by it. What I've learned is that in some positions, you want to make the counter-intuitive move ...Na5, hitting the b3 bishop, rather than ...Nb4, blockading d5.|
|Nov-03-08|| ||Shams: <AnalyzeThis> you and me both. one of the paradoxes of the QGA is that white's e2-e3 system often seems to bring more early trouble for black than white's immediate e2-e4 does. In particular the early Qe2 lines really trouble me. I ended up giving up on the whole system for black.|
