| Oct-11-20 | | stacase: I would have moved 33.Rg6 offering up the Rook again. I didn't see Black's Rook sacrifice and the following Unsuccessful! King hunt. Best I've done on an "Insane" Sunday puzzle in some time. |
|
| Oct-11-20 | | Walter Glattke: First I found a funny BLITZ-chess with 29.Rxf5 gxf5 30.Qxf5 Rxb2+ 31.Kxb2 Qb8+ 32.Ka1 Qb7 33.Bxh5 Rb8 34.Rg5+ possible 34.-Nxg5 35.Qg6+and black wins, 36.-Kf8 37.Qf7+ Qxf7 38.Bxf7 Ne5 39.Be6 Ke8 40.c6 Nxc6 41.dxc6 or white wins? They played 30.-Kg7 with white advantage, the computer plays 30.-Rb7 with littkle white advantage, and you, now possibly you look at my BLITZ idea of Rxb2+ - what mays it be worth!? |
|
| Oct-11-20 | | sudoplatov: Perhaps Kramnik could try 31.Re4 rather than 31.Bxh5. |
|
| Oct-11-20 | | agb2002: White has a bishop and three pawns for both knights. Black threatens Nxd4 and Ne3.
After 29.Rxf5 gxf5 30.Qxf5 Black has 30... Qc8 and if 31.Qxh5 Qxc5 32.Rh4? then 32... Rxb2+ wins for Black. However, 31.Qxc8 Rbxc8 32.c6, followed by Ba6 and c7 if Black doesn't sacrifice the knight, looks very promising. If Black trades the knight for two pawns White still has more than two pawns for the exchange. |
|
| Oct-11-20 | | Brenin: This is a great game to play through, especially the ending, with White's King shielding from the checks among his three advanced pawns. However, as a Sunday puzzle it is rather disappointing, with 29 Rxf5 crying out to be played. Whether this is sound or not (and Black has too many unforced responses for humans -- this one, anyway -- to calculate accurately), OTB it's going to pose Black more than enough problems, especially in a rapid game. A good GOTD rather than POTD. |
|
| Oct-11-20 | | goodevans: Hardly 'insane'. Sac'ing the exchange to expose the K (and getting two Ps in the bargain) is almost routine. On the other hand, Kramnik's <26.fxe5!> was a more surprising and brilliant move. |

| Oct-11-20 | | vajeer: <Honey Blend> 30...Qe8 is interesting. I think in this case after 31.Bxh5 Rxb2, White should play 32. Ka1.
Now of Black forces 32...Rb1+ then 33. Qxb1 Qxh5 34. h3 and White has retained four pawns for a knight and a commanding position. |

| Oct-11-20 | | goodevans: <agb2002: [...] After 29.Rxf5 gxf5 30.Qxf5 Black has 30... Qc8 and if 31.Qxh5 Qxc5 32.Rh4? then 32... Rxb2+ wins for Black.

|
| Oct-11-20 | | vajeer: Looks like computers prefer 30...Kg7 just like Kasparov and so that must be correct...just wondering what is the continuation after 30...Rb7. Black will have rook for four pawns but the position looks horrible no matter what is played! |
|
| Oct-11-20 | | goodevans: <vajeer: <Honey Blend> 30...Qe8 is interesting. I think in this case after 31.Bxh5 Rxb2, White should play 32. Ka1...> There's clearly more to this puzzle than I originally thought. Your line would allow black to continue his counterattack with 32...Qb5. After <30...Qe8> I think white can find something stronger than 31.Bxh5. My first instinct is to continue to add pressure with 31.c6, also blocking off black's counterattack, but this doesn' t work because 31...Nxc6 takes advantage of white's in defended B. So first I pin white's N with <31.Re4>. 
click for larger viewNow not only is the c6 advance pretty much unstoppable but white also threatens to do something nasty with 32.Bd3. |

| Oct-11-20 | | Walter Glattke: Looking at agb with 32.Rh4? see this sharp variation with a "one-move-earlier-mate" by 32.Rg4+ Nxg4 33.Qxg4+ should be draw then by perpetual checks, e.g. 33.Kf7 34.Qe6+ Kg7 35.Qg4+ Kg7 36.Bd3?? Rxb2+ 37.Kxb2 Rb8+ 38.Ka1 Qc3# or Qc1+Bb1Qxb1# or 35.Qg4+ Kh8 36.Qh5+ Kg8!? 37.Qg6+ Kh8 and "dancing" with queen and king Kg8-h8, Qg6-h6. |

Love the white King walk with all the Black heavy pieces still on the board .... Power of pawns .... |

| Oct-11-20 | | Cheapo by the Dozen: Fun attack. But bad puzzle, because of how easy and obvious the first couple of moves were. Trade the Exchange for 2 pawns, tearing open Black's position? Yes please. |

To all damn and stupid Kramnik bashers out there on chessgames.com ("Drawnik" etc.): With the 3 exceptions of A. Karpov, V. Ivanchuk and V. Anand, during Kasparov's reign as world champion only Vladimir Kramnik could play like this against G. Kasparov! |

 | | eternaloptimist: Wow I played the same moves Kramnik played from 29. -> 32. & then I chose 33.♙c6 (which Kramnik chose for his 34th move)! It looks like ♕e6 & ♙c6 r interchangeable for move 33.. I hardly ever get the 1st few moves of an “Insane” puzzle right so I’m feeling really good now!! 😎 |

| | perfidious: <FSR....Of course 29.Rxf5 gxf5 30.Qxf5 should be played. You don't need to analyze much further than that.> Nuff ced!
In a more complex position, one might analyse some lines as a 'control' to ensure the opponent had no active tries, but here there was nothing even the great Kasparov could undertake while awaiting the executioner. |
