| Jan-31-10 | | notyetagm: <KingG: ... Regarding the tactic, I'm assuming your opponent saw it. Did he think he had enough compensation for the pawn(which it looks to me like he does), or that he would somehow trap the rook? Or did he really blunder it?> It was a blunder. Vigorito said he saw the tactical shot 22 ... ♘b6xc4! as soon as he took his hand off his knight after playing 22 ♘c3-b5?!. And yes, that is exactly what he said in the post-mortem, that he had blundered the pawn but maybe he could <TRAP> the rook. |

 | | alexrawlings: How would Kasparov have continued if black had played 38.. Rxg3? |
|
| May-25-10 | | Catfriend: <alexrawlings> A good question. I think that simply taking with 39.Qxh3 is the answer. Now, Black has two options: A) 39..Ke7 40.Ne4 leaves White better, due to the Qh4+ threat, f.e. (one of the possible lines) 40..Bxe4 41.Qh4+ Kd7 42.Nf6+ Kc6 43.Nxe4, with the White queen penetrating to e7 or d4. B) 39..Qxc3 (threatening Re1) 40.Qg7+ Ke7 41.Rg1, a quiet move that forces Black to deal with White's aggression: 41..Rc8 42.Ng8+ and sacrificing the exchange is the best way to postpone imminent destruction. |

| Dec-17-15 | | bennyboy79: 37.Nd7 + and it was over...did Kasparov miss this one?? |
|
| Dec-17-15 | | Catfriend: <bennyboy79> 37. Nd7+ Bxd7 38. Qd8+ (I suppose that's your point?) Be8 0-1 |
|
| Feb-08-17 | | ChessHigherCat: I was looking at 39. Ne4. If 39...Bxe4 then 40. Qd8#. Unfortunately, black can play 40...Qe7 41. Qxe7 Kxe7 42. Nxc3 which looks okay for white but is not nearly as good as Kasparov's line (I taught him everything he knows but he plays even better than me now :-) |
|
| Feb-08-17 | | dfcx: i spent a few minutes trying to get to Nd7+ followed by Qd8+, but then black could simply played Be8. So let's try an alternative move first, 39.Rxg6 fxg6 (or black is a rook down)
40.Nd7+! Bxd7 (or queen lost)
41.Qf6+ Ke8
42.Ng7#
or 41...Kg8 42.Qg7# |
|

 | | al wazir: I wanted to check with the ♕ on d8 instead of f6. That also wins but takes much longer. |
|
| Feb-08-17 | | patzer2: For today's Wednesday puzzle, I went with 39. Nd7+ Bxd7 40. Rxg6 Qe7 41. Rf6  (+3.59 @ 20 depth, Deep Fritz 15). However, stronger is the game continuation 39. Rxg6! fxg6 40. Nd7+ Bxd7 41. Qf6+ Ke8 (41...Kg7 42. Qg7#) 42. Ng7#. For a Black improvement, instead of 24...Raf8 25. Nn2  (+0.68 @ 26 depth, Komodo 10), my computer likes 24...Bb5 25. h5 g5 26. Nd3 = (0.00 @ 23 depth, Deep Fritz 15). |
|
| Feb-08-17 | | EIDorado: What about 39. ... c2? To me 39.Nd7+ looks better than 39. R:g6. |
|
| Feb-08-17 | | stst: The f7 P is somehow a nuisance, for the Q, even reaching d8 after the f6 N goes, will be inter-blocked by the Q, so first clear the R@g6:
39.RxR fxR
40.Nd7+ forks Q BxN
41.Nf6+ .....
if ...... Kg8 ===> Qg7#
if ...... Ke8 ===> Ng7# |
|
| Feb-08-17 | | stst: <39.Nd7+ looks better ...> That's the human self-fulfilling "wish." But it's does not work immediately, even though White should prevail after that...for, as explained, BxN and White's Q cannot deliver # at once... the nuisance? the f7 Pawn.
If Qd8+, Be8 blocks, and White has not effective forcing move (while the f7 P and g6 R are still there!!) |
|
| Feb-08-17 | | AlicesKnight: 39.Rxg6 fxg6; 40.Nd7+. The Q is lost unless Black plays Bxd7, but then 41.Qf6+ leads to mate by Qg7 or Ng7. The Nd7+ works if Black declines the R and plays ...c2; 40.Nd7+ Ke8; 41.Nxc5 Nd1; 42.Nd3 and other lines seem to allow White to keep the material. Let's see - yup, the main line. |

| Feb-08-17 | | mel gibson: I would have played
39 N-d7
which I checked & it still wins.
The computer says:

| Feb-08-17 | | morfishine: Simple enough, exchange down, clearance theme
***** |
|
| Feb-08-17 | | Mayankk: I first tried to get my Queen to d8, after clearing the knight at f6 to some remote corner, but the Bishop kept coming to e8 and block the check. Then I saw that if there was no pawn at f7, then a Queen check at f6 will be very powerful. And of course an easy way to remove this nuisance pawn is to exchange Rooks... |
|
| Feb-08-17 | | agb2002: White has a knight for a bishop and a pawn.
Black threatens c2.
White can expose the black king with 39.Rxg6:
A) 39... fxg6 40.Nd7+
A.1) 40... Bxd7 41.Qf6+ Ke8 (41... Kg8 42.Qg7#) 42.Ng7#. A.2) 40... Ke8(f7,g8) 41.Nxc5 wins decisive material. B) 39... c2 40.Nd7+ Bxd7 41.Rxe6
B.1) 41... Bxe6 42.Qd8#.
B.2) 41... fxe6 42.Qf6+ as in A.1.
B.3) 41... c1=Q 42.Qd8+ Be8 43.Q(R)xe8#.
B.4) 41... Qc7(8) 42.Qe7+ Kg8 43.Rg6+ and mate next. B.5) 41... Be8 42.Qg4 Rg8 (42... fxe6 43.Qg7#) 43.Nf6 B.5.a) 43... Rxg4 44.Rxe8+ Kg7 45.Rg8#.
B.5.b) 43... fxe6 44.Qxg8+ Ke7 45.Qxe8#. |
|
| Feb-08-17 | | zb2cr: Initially I thought 39. Nd7+, Bxd7; 40.Qd8 would be mate--but Black interposes the Bishop on e8. So eventually I hit on Kasparov's actual line. |
|
| Feb-08-17 | | YetAnotherAmateur: I was looking too hard at 39. Ne4. This did several things that seemed worth doing:
1. Opened up the threat of Qd8, especially if black was dumb enough to play Bxe4
2. Threatened the black queen.
3. Threatened the black c3 pawn.
4. Overprotected the Rg3.
Play might have continued along the lines of 39. Ne4 Qd4 40. Nxc3 Nd3 41. Re2 without much more than that pawn gained. And that's the proof that I'm not Kasparov and never will be, because his line was much simpler and much more advantageous. |

 | | gawain: <dfcx: i spent a few minutes trying to get to Nd7+ followed by Qd8+> Me too. |
|
| Feb-08-17 | | Sularus: went for Nd7+ first |
|
| Feb-08-17 | | catlover: I'm with the group that analyzed 41 Qd8+. Don't know why I didn't see the simpler 41 Qf6+. |
