|Jan-02-08|| ||tamar: 28 c4! was well calculated. Good to see David bouncing back.|
|Jan-03-08|| ||syracrophy: Poor Korchnoi. He received a very good beating! What a game!|
|Jan-03-08|| ||Honza Cervenka: 28. c4 is pretty shot which Korchnoi missed or underestimated when he played 27...Bb5. 28...dxc4 or 28...Bxc4 fails for 29.Qc3 with threat of mate on g7 and hanging Knight on g6. 27...Bxf5 28.Qxf5 Nf8 seems to be necessary.|
|Jan-03-08|| ||Bobsterman3000: 28. c4 wow!!
|Jan-03-08|| ||Bobsterman3000: Best game of 2008 so far :-)|
|Jan-03-08|| ||fgh: Indeed, quite possibly the best game of the year 2008 so far :-)|
|Jan-03-08|| ||whiteshark: Why not <24...♕c4> to reduce pressure:
<25.♕x♕ ♙x♕ 26.♗x♘ ♙x♗ 27.♘e5 ♖e8 > ?

|Jan-08-08|| ||suenteus po 147: Impressive game by Navara. It's not often one catches Korchnoi off-guard in the Tarrasch. And when one does his last name usually begins with K.|
|Jan-20-08|| ||Lightboxes: Why not 29.Qh7 Ne6 30.Qg8 Ke7 31.Qxf7 Kd6 32.Rxe6 mate
??? Seems like black can do nothing about it.|
|Jan-21-08|| ||areknames: Lightboxes, if 29.Qh7 then follows ...Nh3+!! Seems to me black has at least a draw.|
|Feb-15-08|| ||whiteshark: So, why not 24...♕c4?|
|May-15-08|| ||charliechaffka: So, why not 24...Qc4? Looks good to me.
Also wonder why, maybe he thought he could do better. Mind you Victor must be 77.?
|Sep-28-14|| ||diagonalley: 29 NxP+ stands out as the best candidate for first move... but 30.Q-B5 to follow is very difficult... (pretty sure i would never have found it)|
|Sep-28-14|| ||Cheapo by the Dozen: Material is substantially even. White has a queen and pawn hanging, however, so if he can't spin up an attack he'll probably be at a disadvantage shortly.|
The obvious move is 29 Nxh6+. If Black accepts, he is mated in two. If he declines with 29 ... Kf8, we get
29 Nxh6+ Kf8
and I don't see any good way for Black to stop Qh8#, and his bishop is hanging as well.
So the main line becomes:
29 Nxh6+ Kh8
30 Nxf7+ Kg8
31 Qh7+ Kxf7
If nothing else, White will be up a pawn, with better pawn structure and an attack.
This is seeming way too easy for a Sunday. What am I missing? ... Bxf2+ counterplay doesn't seem to amount to much. Maybe there's something with 31 Qf5 better than my line (that was actually my first choice), but mine seems simpler and sufficient for a nice advantage.
|Sep-28-14|| ||Cheapo by the Dozen: Yep, there was something better with Qf5 indeed. :)|
|Sep-28-14|| ||chessgames.com: There was a typo on the homepage: 29.? should have read 28.?|
Corrected now, our apologies.
|Sep-28-14|| ||offramp: It's slightly odd that black is threatening 29...Nh3+.|
|Sep-28-14|| ||plumbst: Like the other puzzles this week, not much choice since White loses his c pawn and attack (b1-h7 battery) if the Queen retreats. |
29.Nxh6+! Kf8. Forced otherwise it's mate (29.Ne7+ will be explained next move)
30.Qh7. (if 30...Ne6 31.Qg8+ mates) The critical position, threatening mate, but because White's knight no longer guards g3 Black has a sneaky defense..
If White played 29.Ne7+, he would have no good move here.
31.gxh3 Qg3+ mates. 31.Kh1 Nxf2+ 32.Kg1 Nd3+ 33.Kh1 Nxe1 34.Nf5 Ke8 and Black escapes with extra material 31.Kf1 Bxc4+ 32.Bd3 Bxd3+ 33.Qxd3 Bxe7 34.Qh7 Qc4+ 35.Re2 f6 36.gxh3 Qf4 and again Black is up material.
However, it's slightly different in the main line.
31.Kf1! (31.Kh1 Nxf2+ 32.Kg1 Nd3+ 33.Kh1 Nxe1 34.Qg8+ Ke7 and Black's King still escapes)
Now the difference is seen, as Black doesn't have Bxe7.
33...Qd6. (33...gxh6 34.Qh7 f6 35.Qxc7; 33...Nf4 34.Qh7 Ne6 35.Qg8+ mating; 33...g6 34.fxg6 with a winning attack; 33...Be7 34.Qh7 Ke8 [34...Qc4+ 35.Re2 Qc1+ 36.Ne1] 35.Qg8+ Kd7 36.Qxf7 winning material)
34.Ng4! Saving the knight, guarding f2/h6, and maintaining the attack on Black's knight.
35.Qh7 Ne6 (35...f6 36.h6; 35...f5 36.Qxf5+ Kg8 37.h6)
36.h6 gxh6 (36...f6 37.hxg7+ mates; 36...g6 37.Ng5; 36...Ke7 37.hxg7)
37.Nxh6 Qd7 (37...Rd7 38.Nf5)
Edit: Ok, 33...Bb4 looks pretty unclear.. forgot that 29.Nxh6+ cleared f5 for 30.Qf5; much smarter and straightforward since White's attack is too strong. Count it as a miss for me.
|Sep-28-14|| ||lostgalaxy: Anyone tried to sac the queen too? :-)
Anyway i found out finally it only needs to a pawn sac, even though the title was "insane".
|Sep-28-14|| ||morfishine: I dismissed 28.c4 too early thinking Black was ok after 28...Bxc4|
I could only guess that 28.Nxh6+ was the move
|Sep-28-14|| ||Richard Taylor: I found 1. c4 but the rest I just looked up as it is very complex. I think would have had to play it move by move...|
Good attacking game by Navara!!
|Sep-28-14|| ||Richard Taylor: The idea is also, of course, to play 2 Qc3 if allowed. I did see the Black responses but I was too tired to bother with it, there looked to be a lot of lines.|
|Sep-28-14|| ||epicchess: This need to be potd on a thursday or friday:M G Isakov vs S Ramanujam, 2014 Some of the ones on those days are below standard. However, the saturday sunday ones are very interesting indeed! Took me a while to get this one.|
|Sep-28-14|| ||agb2002: Not much time today to give a decent analysis.|
|Sep-30-14|| ||patzer2: Here's my look at the recent Sunday (28. ?) puzzle and game using Fritz 12:|
<24. Bc2 Kf8> Better is 24...Qc4 = to , which puts up more resistance and offers practical drawing chances.
<25. h4 Kg8> Again, Black should consider 25...Qc4 = to .
<26. Nf5 Bc5 27. h5 Bb5 28. c4!!> This stunning clearance sacrifice solves the Sunday Sep 28, 2014 puzzle.
<28.. Nf4> The pawn is poisoned as 28... Bxc4? 29. Qc3 or 28... dxc4? 29. Qc3 win a piece with a double attack threat (mate or drop a piece).
<29. Nxh6+! Kf8 30. Qf5!> This clever and essential move both attacks and defends.
If 30. Qh7?!, then 30...Nh3+! 31. Kf1 (not 31. gxh3?? Qg3+
32. Kh1 Qxf3+ 33. Kh2 Qxf2+ 34. Kh1 Qxe1+ 35. Kg2 Qf2+ 36. Kh1 Qg1#) 31...
Bxc4+ 32. Bd3 Bxd3+ 33. Qxd3 Bb4 34. Nxf7 Kxf7 35. gxh3 Bxe1 36. Ng5+ Ke7 37. Qe3+ Kd6 38. Qf4+ Kc6 39. Qa4+ b5 40. Qc2+ Kb6 41. Qxc7+ Kxc7 42. Ne6+ Kd7 43. Nxd8 Bxf2 44. Kxf2 Kxd8 = throws away the win and gives Black a draw.
<30...Bxc4> As good as any in a lost position.
If 30... gxh6, then 31. cxb5 Rc8 32. Ba4 axb5 33. Qh7 f6 34. Qxh6+ Kf7 35. Bb3 Bb4 36. Rd1 Rg8 37. g3 Rg7 38. Kf1 Ne6 39. Bxd5 Qd6 40. Bb3 Qc6 41. Nd4 Qh1+ 42. Ke2 Qe4+ 43. Qe3 Qxe3+ 44. Kxe3 Bc5 45. Bxe6+ Kf8 46. Bf5 wins.
If 30... Bc6, then 31. Qh7 wins.
<31. Ne5 Ne2+ 32. Rxe2 Bxe2 33. Nhxf7 Ke8 34. Qg6 Qb6 35. Nd6+ Ke7 36. Nf5+ 1-0> Black resigns in lieu of 36...Kf8 37. Qf7#.
