And now Stockfish 1.9.1 gives the following truncated line @ depth 30: 21. ... Bd4 22. a4 Kh8 23. axb5 (-0.04)
|Apr-11-11|| ||LIFE Master AJ: My analysis of this game ...
|Mar-23-15|| ||FSR: Imagine, at the time of this game Kasim was the reigning FIDE World Champion. I'd say Kasparov was a little better.|
|Mar-23-15|| ||LoveThatJoker: A nice win by, the then former World Champoion, Kasparov in his final tournament as a competitive chess professional.|
<FSR> Kasparov was ever so slightly the better chess player at the time. :D
|Mar-23-15|| ||kevin86: the extra pawns will win for black.|
|Mar-23-15|| ||rainingpieces: 32..Rh2+ looks nice, but the king can escape to f3. An interesting detail in my opinion|
|May-22-15|| ||greenfield67: Hmm. I was so focused on stopping 30.Qe6+ that I ruled out everything which allowed it, including 29...Bg3. And so my question - how bad is 30.Qe6+ after the game continuation?|
|May-22-15|| ||M.Hassan: "Difficult"
Black to play 29....?
Black has a Bishop+pawn for a Rook.
<if 31.hxg3 Nxg3+ and winning the Queen>
White can no longer check the King and has to save his Queen:
White has to continue a Queenless game.
Time to check
Miles different!!! but I don't see what is wrong with my line. Any comments appreciated.
|May-22-15|| ||al wazir: <My solution was similar to <M.Hassan>'s: 29...e2 30. Qxe2 Nxg3+ 31. hxg3 Qxg3 32. Qe6+ (32. Qf1 Rf4, threatening Rh4+) Kg7 33. Qd7+ Kh6 34. Rf1 Rf4 35. Rxf2 Rxf2, with mate to follow.|
|May-22-15|| ||greenfield67: <al wazir> I had what you had up until 32.Qe6+, but I think White probably has defensive resources thereafter that I haven't properly considered yet: Ra7+ looks like it might be useful somewhere down the line.|
|May-22-15|| ||dfcx: I would play 29...Bxg3
If white accepts the sac,
30.hxg3 Nxg3+ 31. Kg1 e2
A. 32. Re1 Qc5+ 33. Kg2 Qf2+ 34. Kh3 Nf1
white can't prevent mate without giving up its rooks for black's knight and pawn.
35.Rxf1 (Rxe2? 36.Rf3+ and mates) exf1=Q+ 36.Rxf1 Qxf1+

White will lose even more material to avoid mate
B) 32.Qe6+ Qxe6 33.exd1=Q+ 34.Rxd1 Ne2+

|May-22-15|| ||SimonWebbsTiger: another of those games which is just too famous to be a puzzle, unless you haven't seen it before in which case well done!|
The game was very important for the theory of this variation of the semi-slav.
|May-22-15|| ||Penguincw: Hmm, I though 29...e2 followed by some piece sac on g3 was going to be played. :||
|May-22-15|| ||thegoodanarchist: Another gem from Gazza!
GK has got to be my third favorite player of all time, just behind Carlsen and Fischer. I love his dynamic play.
|May-22-15|| ||kevin86: Another brilliant finish for Kasparov!|

|May-22-15|| ||patzer2: For our Friday puzzle we have a familiar Kasparov game which has been well analyzed many times.|
Rather than going into detail on the Friday puzzle solution 29...Bxg3!!, I'll venture a guess as to where White went wrong.
Seems to me 21. Nd5?!, allowing 21...Bxd5 22. exd5 Bxg2+ , is where the game turns in Black's favor.
My computer (Deep Fritz 14) prefers 21. Qe2 =, but I don't like the positions arising after 21...Bd4 22. a4 Bc6 =.
Instead, after a bit of trial and error against the computer, I came up with 21. h3 = as a suggested improvement.
Playing it out move-by-move against Fritz, White forces a draw by perpetual check after 21. h3 Bxf2+ 22. Rxf2 Ng4 23. Qxg4 Qxf2+ 24. Kh2 Qxc2 25. Qe6+ Kh8 26. Rf1 Rg8 27. Qxe5 Qxb2 28. Rf7 Bxe4 29. Rxg7 Rxg7 30. Qe8+ Rg8 31. Qe5+ =.
|May-22-15|| ||Chess Dad: <M. Hassan: Miles different!!! but I don't see what is wrong with my line. Any comments appreciated.>|
I am not good enough to spot the error myself, so I turned to the silicon monster.
31. Ra7 and 31. Qe6+ both rate at about +1.05.
But yeah, if White makes the 31. Qg2 error, you've got quite the advantage at about -7, and 31. hxg3 is #8 after Nxg3.
|May-22-15|| ||agb2002: Black has a knight and a pawn for a rook.
Black must take into account the simplifying maneuver Qe6+.
This suggests 29... Re8, threatening 30... e2:
A) 30.Qe2 Nxg3+ (slower looks 30... Qxg3 31.hxg3 Nxg3+ 32.Kh2 Nxe2 with the idea Nf4, e2, etc.) 31.hxg3 Qxg3 32.Qf1 e2 33.Qg2 exd1=Q+ 34.Rxd1 (34.Bxd1 Re1+ and mate next) 34... Re1+ 35.Rxe1 Qxg2+ 36.Kxg2 Bxe1 - + [2P].
B) 30.Be4 Qe5 31.Bf3 e2 32.Re1 Bxe1 33.Rxe1 Qxb2 looks very good for Black.
I don't have time for more.
|May-22-15|| ||M.Hassan: <Chess Dad31. Ra7 and 31. Qe6+ both rate at about +1.05.>|
I can see the advantage of 31.Qe6+ but don't see any reason(or undrlying reason) for 31.Ra7. Do you?
|May-23-15|| ||patzer2: <agb2002> After 29...Re8, Deep Fritz 14 shows White having reasonably good drawing chances after 30. Bf5! when play might continue 30...e2 31. Be6+ Rxe6 32. Qxe6+ Qxe6 33. dxe6 exd1=Q+ 34. Rxd1 Nf6 35. Rd8+ Kg7 36. Kg2 Be3 37. Rb8 Bd4 38. Rxb5 Ne4 39. Kf3 Nd2+ 40. Ke2 Nb3 41. Rb4 Bxb2 42. Rxc4 Nd4+ 43. Kd3 Nxe6 44. Rb4 Be5 45. Ke4 (-0.47 @ 29 depth).|
|May-23-15|| ||patzer2: In trying to solve the Friday puzzle, I had no trouble remembering 29...Bxg3!! 30. hxg3 Nxg3+ .|
However, I had difficulty finding a refutation to White's strongest defense 31. Kg1.
The link given in 2011 by <LMAJ> and the analysis posted yesterday by <dfcx> both show the winning reply to 31. Kg1 is 31...e2! 32. Qe6 Qxe6 33. dxe6 exd1(Q)+ (-2.53 @ 23 depth, Deep Fritz 14).
|May-23-15|| ||SimonWebbsTiger: For those interested, David Vigorito's old book "Play the Semi-Slav" (Quality Chess 2008) has this as one of the illustrative games and thus contains some theory and annotations to the game.|
21. Qe2 was played later, and recommended as strongest in Dreev's excellent book "The Meran and Anti-Meran Variations" (Chess Stars 2011), when 21...Qe6! gives black fine play, e.g. Korotylev-Dreev, Fuegen 2006.
|May-23-15|| ||agb2002: <patzer2> Thank you!|
I saw the first few moves but gave probably too much importance to the possibiilty of an eventual Qe6+ and didn't find much time to study the position yesterday.
|May-27-15|| ||thegoodanarchist: <patzer2: For our Friday puzzle we have a familiar Kasparov game which has been well analyzed many times.|

Just as Captain Kirk reprogrammed the Kobayashi Maru simulator to allow victory, rather than complying with the simulation rules, you have gone rogue and rewritten the rules to suit your purposes!
Should I be outraged? Or should I be impressed?
