Kibitzer's Corner
< Earlier Kibitzing  · PAGE 2 OF 2 ·  Later Kibitzing>
Aug-21-05  sfm: OMG, this is brilliant!! This combi is as deep as it get, with all moves, until the very last, being essential. Even at the position after 20.-,Kg8 it would still be a hard "White to play" to solve. The blocking of Black's f-pawn to disable the defense of h7 makes one think of Fischer vs Benko, 1963 but this is much deeper.
Didn't see this one to the end and wouldn't have conceived it over the board.
Aug-21-05  sfm: A perfectionist may note that 21.Bf6+ should just be 21.Bf6
Aug-21-05  JohnBoy: <zothique> - I agree that the knight is poissoned. 18...Ncxd3 gets the troublesome white-squared bishop off the board right away.
Aug-21-05  The beginner: To complicated for me :)

My candidate moves was eather Nxg7, or Rf3.

But calculating the entire line with all its posibilitis is to complicated.

Nxg7 looks pretty strong, lots of white pieces waiting to jump on the black king, or Rf3 also brings yet another attacker towards the "weak" black king position. (g7, and h7 is only defended by the king)

I wonder how the game would continiue if black had played 18 ..Ncxd3 instead of Kxg7, it surely dont look good for black with a hole in his g file. White would proberly win anyway, but figuring out the entire line with all its posibilitys is way over my head :)

Aug-21-05  hedgehog: I'm kind of happy that I saw RxN, but I had it straight off on Move 18. That does work dosen't it? I think it's beautiful the way that the revealed attack on h7 allows white to occupy f6.
Aug-21-05  Wyn Evans: A nice combination indeed but perhaps leading to no more than a ( , around 1.17, 15-ply) advantage for white, not outright victory. I've been looking at it with Fritz 8, Junior 9 and Tiger 15. It's Junior's analysis that I'll give some lines of,discarding many variations and concentrating on the strongest lines. Oh, and... I don't pretend that I allowed the software lots of time to get THE definitive answers. It may be that just a few more seconds looking at each tree would have led to position assessments more substantially in white's favour. But I don't think so. After 18. Nxg7 therefore 18. ... Ncxd3
19. Bxd8 Qxd8
20. Qh6 Kh8
21. Nh5 Nxh5
22. Qxh5 Rg8
23. cxd3 Rg5
24. Qf3 ( , 1.11, 12), or, as above until 22. Qxh5 then

22. ... Nxb2
23. Qxe5+ Kg8
24. Rf3 Re8
25. Raf1 Rc8
26. Rg3+ Kf8
27. Nd5 Bxd5
28. Qg7+ Ke7
29. Qg5+ Kf8
30. Qh6+ Ke7
31. exd5 Qxd5
32. Qf6+ Kd7
33. Qxb2 Qe5 ( , 1.17, 12), or as in last variation until 26...Kf8 then

27. Qg7+ Ke7
28. Nd5+ Bxd5
29. exd5 Nc4 (=, 0.00, 12)

Aug-21-05  John Doe: Oh man, I screwed up the move order. I pushed pawn before moving the bishop... Black can stop the attack by pushing his f pawn.
Aug-21-05  jahhaj: <Wyn Evans> I think you're being generous to White. For instance in your first line where's the advantage to White after the simple 22...♘xb2?

Black has some surprising resources in this position such as pressure along the g file after ♔h8 and ♖g8.

Of course White and Black have lots of alternatives but it's hard to find any substantial advantage to White after 18...♘cxd3. But I think the position is far too complex for even a GM to calculate. I'm not at all surprised the Black didn't play 18...♘cxd3.

Aug-21-05  ckr: Bf6+ Check?, is the king on g8 or h8? Was 20.Kh8 rather than Kg8?

Nxg7, so strong nothing else deserves consideration - even if I could not follow it all the way to a mate. To me, it was just recognizing the attacking possibilities after the king field was broken down, well worth a knight.

Aug-21-05  ckr: King on h8 would explain 25.Kf1 rather than 25.gxh3 allowing the black rook to launch some counter attacking possibilities.
Aug-21-05  mark1800: A nice sacrifice, followed up by the exchange sac, opening up various mating lines. I had seen this game before in the life and games of Mikhail Tal book. Tal comments: "After the game the opinion was expressed that Ravinsky's combination could have been refuted by means of 18...Ncxd3,but I did not agree with this point of view (either because of 19.Bf6 or more likely 19.Qg3)" Tal's attempts to 'follow' this game can be seen in the game Tal vs Pasman 1953.
Aug-21-05  dhotts: I think Black has adequate defenses with 18...Bxg5 and if 19.Qxg5 then 19...f6 or Ng6!...What am I missing?
Aug-21-05  sharpnova: 18. Nxg7 Ncxd3 and black is maybe ok

i picked Nxg7 before loading the page, but i hesitated due to Ncxd3

Aug-21-05  ckr: <dhotts What am i missing> I don't think the defense holds up.

19...f6 20.Nxe6 fxg5 21.Nxc7 - seems worse for black

19...Ng6 20.Nh4 not - looking good either

  kevin86: A long series of moves has led to inescapable mate-and black is left to spite checking. A very refreshing game!!
Aug-21-05  sfm: <mark1800: Tal: ...either because of 19.Bf6 or more likely 19.Qg3> OK, it does not sound like Tal put a lot of analysis into it. 19.Qg3 is typical tal - the more hanging pieces the better! Wonder what Mr. Fritz would say to that?
Aug-21-05  jahhaj: <sfm> After 18.♘xg7 ♘cxd3 19.♕g3 ♗xg5 20.♕xg5 ♕d8 Fritz doesn't find much for White.

21.♘xe6+ ♕xg5 22.♘xg5 ♘xb2 looks pretty level.

21.♕h6 (the threat of ♘h5 keeps Black's knights tied down) ♔h8 22.cxd3 ♖g8 23.♘xe6 fxe6 and White is possibly worse (watch out for the threat of Rg6 trapping the queen).

Aug-21-05  Frankly: Okay. I see someone got tired of all those 'oh, it was so easy - why waste my time?' quips. So he/she posted the monster problem.

I think I prefer the ones I have a shot at solving...

Aug-21-05  snowie1: Eureka! 18 Bxb5...axb5 19 Nxb5...black moves his Q ? and 20 Nd6! Now, after black's Q moves (again?), 21 Nxg7...Kxg7 22 Nf5+...Kg8 (if Bxf5, 23Qh6+...Kg8...etc) 23 Bf6...now if Bxf6 24 Qxf6...and exf5 heading to help the Q mate.

  Richard Taylor: I ahd all thes ideas butmissed hteincredible 24 e5!! but I was looking for that idea - I looked for an hour and missed it - I thought it might be Nxg7 then was looking at Rf4 then B:b4 and R:f4 and Nd5 or Ne7+ - I wanted that B on d3 to work but couldnt see how - in my lines it kept getting taken - but this was a great combination by Grigory Ivinsky - very beautiful. Had me beat...
Aug-21-05  sharpnova: 18. Nxg7 Ncxd3 and black is maybe ok

anyone else agree? aka.. this puzzle is not a white to move and win

  patzer2: White's demolition of pawn structure combination with 18. Nxg7!! sets up an instructive mating attack on Black's weakened castled position.

  chancho: In the "Life And Games of Mikhail Tal", this game is called "spectacular" by Mikhail Tal, and he also says of it: <"I am unable to resist the temptation to give it in full">

It is a splendid game.

Jul-08-06  Open Defence: This game was shown on ICC by the bot Mr Spock... very nice :)
