| Jul-27-12 | | OneArmedScissor: <34. ...Be5 35. Qg5+> |
|
| Jul-27-12 | | Everett: I don't care what the comps say; Black must play <22..Nc5> |
|
| Jul-27-12 | | parmetd: Maybe better is to play 16.... Nc5. I don't have an engine handy but this seems the most natural continuation. |
|
| Jul-27-12 | | Marmot PFL: How about 29...hxg2 30 Kxg2 Nh3! (threat Nf4+) 31 Kxh3 Qh5+ 32 Kxg3 Bh6 33 f4 (if the queen moves Bf4+ leads to mate) Bxf4+ 34 Rxf4 exf4+ 35 Qxf4 (35 Kg2 f3+ or Kf2 Qh2+ are worse) Ra3+ followed by Rxf4. It seems in the King's Indian no matter how careful white is, if black is alert he always gets tactical chances. |
|
| Jul-27-12 | | Eyal: <Marmot> Why not 31.Bxg3 in your line? (31...Nf4+ 32.Kh1) |
|
| Jul-27-12 | | Marmot PFL: <Eyal> 31 Bxg3 is a good idea, decline the piece and keep the pawn, then 31...Bh6 32 Qc2 Nf4+ 33 Kh1 Rf5 34 Rg1 and Rh5+ loses to 35 Bh2. Now there doesn't seem much more for black to do, and white plays Bh2 and b6 and so on. Still lines like this are not so easy to meet OTB, as when Nakamura with black beat Anand with an unsound attack. |
|
| Jul-28-12 | | MethodMan: <Everett> 22. Nc5 just gives up a piece for no reason. The comp says it's a bad move because it's a bad move. |
|
| Jul-28-12 | | Eyal: Basically, Black tried here to play a "classic" type of KID K-side attack, but did it with a badly misplaced knight – first on a6 (instead of e7) and then, of course, on b8, where it also stands in the way of the rook on a8. Note that this had to do with Nakamura playing an early 7.d5 in the opening (instead of the more usual 7.0-0 followed by d5 only in the next move), not allowing the black knight to develop through c6. |

|
| Jul-28-12 | | elnanes23: Ouch!! |
|
| Jul-29-12 | | DK8: @HeMateMe... "he went down without a fight." I can't see a good move for black - his knight is completely paralysed. Least worst might be 34... Bh6 35. QG4 QxQ 36. RxQ ... not much sunlight there either. There may not be an unequivocal forced end but even assuming the best from black and weak play by white - no answer to the f file pawn really. |
|
| Jul-29-12 | | Riverbeast: I'm surprised none of the analysts, including Nakamura, did not discuss what I thought may have been black's losing move In the video analysis, Nakamura thought 22...Nb8 was the losing move...Maybe it is, even though it was apparently the comp recommendation At first glance, I thought the losing move was the next one - 23...Bxd5 On general principle, black's attack on the kingside usually fails without the QB Instead of 23...Bxd5, 23...Rf7 would be a typical defensive/repositioning move in the KID...And seems a lot more natural |
|
| Jul-29-12 | | Eyal: <Riverbeast> According to Houdini, 23...Bxd5 is the only move which somehow keeps Black in the game - after every other move, including Rf7, the evaluation for White skyrockets with the Q-side break 24.b6!; I've tried to play it out a little and apparently Black does get crushed. Btw, I don't think what Nakamura says is exactly that 22...Nb8 is the losing move. He's looking at 22...g3, which doesn't work apparently, and says that if this doesn't work and Nb8 is the best there is, it means that Black is strategically lost by this stage (which seems reasonable); according to this line of thinking, the decisive mistakes were made earlier, and were related to the whole faulty concept of a pawn storm on the K-side which isn't well-supported by Black's setup in this variation. |
|
| Jul-29-12 | | Riverbeast: <Eyal> That's interesting I was just looking at it in my head, but I thought after 24. b6 Nxc6 25. Nxc7 Rxc7 26. bxc7 Rc8, black was still in the game But of course black is down material, and I can't see as far as the silicon beast...What does Houdini say about this line? |
|
| Jul-29-12 | | Eyal: Well, White plays 27.Rb7 and then there isn't any immediate forced win, but it seems that Black's attack on the K-side just isn't going anywhere while White can increase the pressure on the Q-side. Here's an example of an attempt at immediate counter-play by attacking White's advanced pawn that doesn't work: 23...Qf7 28.fxg4 Rxc7 (28...hxg4 29.Bxg4 Bxg4 30.Qxg4 Rxc7 31.Rxc7 Qxc7 32.Qe6+ followed by Nc4 or Rc1) 29.Rxc7 Qxc7 30.gxh5; if Black starts with 27...gxf3 then after 28.Nxf3 the d6 pawn (which now isn't defended by the c-pawn) is under attack. |

| Jul-29-12 | | Riverbeast: <White plays 27.Rb7 and then there isn't any immediate forced win, but it seems that Black's attack on the K-side just isn't going anywhere while White can increase the pressure on the Q-side> After 27. Rb7 I was thinking black would continue with 27...g3 I'm assuming the comps say black is lost...But they often say that in the KID It looks like for the sacrificed material, black has gained some time, temporarily stalled white's attack, and is starting to activate a little (?) |
|
| Jul-29-12 | | Eyal: Well, there isn't any one forcing main line so it's difficult to check everything; one point that's worth mentioning, though, is that after a pawn exchange on g3 and 29.Bb6 White has the strategic threat of exchanging LSBs by Bc4 (an idea mentioned a couple of times by Nakamura), which would significantly reduce Black's attacking possibilities. |
