| Mar-26-14 | | PJs Studio: With the lovely Rd2 holding all the defensive squares down I figured this out rather quickly... But I thought black would play on. Intimidated by his opponent perhaps? (Can't blame him.... Nezh! ;) |

| Mar-26-14 | | Castleinthesky: Got it and Rashid's one of my favorites to boot! |

 | | gawain: How sure are we about the date 1961 for this game? Database for Hiarcs places this game in Chigorin Memorial tournament, 1965. Nezh and Krogius did meet at the 1965 tournament and Nezh won. http://al20102007.narod.ru/it/1965/... |
|

| | gawain: In fact Krogius had won this tournament in 1964, the previous year. In 1965 Krogius finished 5th but this game was his only loss. Nezh finished 10th |

You read my mind.
<patzer2 after 41...Bf3 42 Ne3 black would have beem winning with 42...Nxf4.
White best move 43Nxf5.>
Really?
After 43.gxf4 Bh4 44.Qxf3 exf3 45.Nxf5 Rg2+ 46.Rxg2 fxg2 47. Nxh4+
White has 3 pieces vs black gueen and the win. |

Black has a winning attack and White will at least have to give back material. |

Rashid Nezhmetdinov - Nikolai V. Krogius;
[C93] / Event?, 1961
[A.J.G.]
A quick look at this game.
(POTD / Wednesday; March 26th, 2014.)
The game begins as a Ruy Lopez / Spanish.
[See MCO-15, beginning on page # 42.
See also: Opening Explorer 1.e4 e5; 2.Nf3 Nc6; 3.Bb5 a6; 4.Ba4 Nf6; 5.0-0 Be7; 6.Re1 b5; 7.Bb3 0-0; So far, it is all normal moves ... the main line. ("Book.") 
click for larger viewThe Spanish has been a favorite of both amateurs and masters. 8.h3, (avoidance)
By playing this, "Super-Nez" shows that he does not want to face a possible gambit. [RR 8.c3 d5; Marshall.]
8...d6; 9.c3 h6!?;
Black is the first to try and vary from the main line, 9...Na5; could transpose back to stem variations.
(9...h6; is also useful to avoid a later Bg5/pin by White.) [RR 9...Na5 ; - Tchgorin. ]
With his next move, White avoids a large chunk of standard opening theory. 10.d3!?, (solidity)
Nezh might have played this to avoid a prepared line, in his day, Krogius was known as a savvy openings specialist. Of course 10.d4 would probably transpose back to the main lines. [ 10.d4 Re8; 11.Nbd2 Bf8; Geller vs A Matanovic, 1962. ] 10...Be6!?;
Black runs into potential problems with this move ... (After an eventual d2-d4 by White, Black faces a pawn fork on d5.) [ Probably better was: RR 10...Re8; 11.Nbd2,  - Fritz 13 & Powerbook. ] 11.Bc2 Re8; 12.a3 Bf8;
This is solid, Fritz likes 12...d6-d5; instead.
Both sides now do standard maneuvers, Black redeploys his DSB to g7. 13.d4 Bd7; 14.Nbd2 g6; 15.Nf1 Bg7; 16.d5 Ne7; 17.c4 c6; 18.Ne3 cxd5; 19.cxd5 Nh5; (plausible)
Black aims to grab the f4-spot as a good outpost for his Knight. 
click for larger view White has a solid space advantage here, even the computers tend to under-estimate this fact. 20.Kh2 Rf8!?; (20...Qb6; - Fritz.)
21.Bd2 f5!?;
Black looks to get a break in, but this might be the wrong time to do it. Now "Super-Nez" gets a lot of weak squares on the K-side to pick on. Instead of this, the simple play of 21...Nf4; seemed to give Black a playable game. White now plays to break open the center and then fix things with f2-f4. 22.exf5 gxf5; 23.Nh4 Nf4; 24.g3 Nfg6; 25.Neg2 Nxh4; 26.Nxh4 Rc8; 27.f4!? e4;  White has gotten the type of game that he wanted ... (I guess.) 
click for larger view The engines all seem to show "evals" that indicate that Black is slightly better. 28.Rb1 Rf7; 29.Bb3 a5!; 30.Re2 a4; 31.Ba2 Bf6; 32.Ng2 Rg7; 33.Bb4 Be8; Black looks to sneak in a pin (on h5); the boxes like playing the BQ to the b6-square. |

34.Rc2! Rxc2; 35.Qxc2 Bf7!?; 36.Rd1 Kh7; 37.Qf2 Bh5!?; 38.Rd2 Ng6; 39.Bb1 Bf3; 40.Ne1 Bh5; 41.Ng2 Bf3; Maybe Black was hoping for a draw? (Both players could get this by repeating moves, Ne1, Bh5; Ng2, Bf3; etc. Three-fold repetition.) Given what happens next, this would have probably been the correct way for this game to end. 42.Ne3?, (blockade?)
Nezh put his Knight directly in front of his opponent's passed pawn, which is exactly what Nimzovich said you should do. Here, however, the move contains a tactical flaw. [Better was: >/= 42.Ne1, '=' ]
42...Ne7?!; (Rats!)
This is a logical (safe) move, but Krogius missed his chance at a big-time tactical shot. [ Much better was: >/= ¹42...Nxf4!; 43.Nxf5,
The engines all seem to pick this move.
(Even worse (for White) was the following variation:
‹43.gxf4? Bh4!; 44.Qf1!? Bg3+!; 45.Kg1 Bf2+!; 46.Kh2▢ Qh4!, ) 43...Qd7!; 44.gxf4, (Best?)
Once more, White does not have a lot of (good) options left. (44.Bxe4 Bxe4; 45.Qxf4 Qxf5; )
44...Rg2+; 45.Qxg2 Bxg2; 46.Kxg2 Qxf5; (Black's winning.)
when all the engines seem to "think" that Black has an overwhelming position here. ] 43.Qe1 Qb6?; (Gak!)
Now Black virtually blunders ...
click for larger view Now it is Nezh's turn to find a tactic ... and he does not fail us. (The position - just above - for the POTD.) [ Much better was: >/= 43...Kg8!; 44.Rc2 Bd4 ∞; when Black was no worse. ] White to play: (move #45).
44.Nxf5! Nxf5; 45.Bxe4,
Apparently Black resigned here.
A nice game by our hero, but Black also missed his chances. [ White wins in all variations: 45.Bxe4 Re7; A pin, does it win? (Or 45...Bxe4; 46.Qxe4 Kg6; 47.g4, )
46.Bxf5+ Kg7; 47.Be6 Rc7; 48.Qg1!, +2 Pawns. White has a won game. ] 1-0 |
|
| Mar-26-14 | | kevin86: An unusual fork by white: knight and bishop. Black will surely lose material or be checkmated soon. |
|
| Mar-26-14 | | Once: <Patzer2> That is a fascinating line. Fritz agrees. Instead of the game's 42...Ne7, black would have had a stronger attack with the surprising 42...Nxf4 - which <LifeMaster AJ> has also annotated. I suppose that the side with a paratrooper piece deep in enemy territory has an obligation to support that piece. Otherwise it could fall prey to an undermining and encircling attack, such as in our POTD. <BOSTER> Really. After 43.gxf4 Bh4 44.Qxf3 exf3 45.Nxf5, we get to here: 
click for larger viewNow the poor move 45...Rg2+ does indeed give white three pieces for the queen, with advantage to white (although not yet a win). But we don't have to be so compliant. Why throw away a piece to a discovered check when we don't have to? It is black to move and he has a number of ways of keeping an edge. Fritzie prefers the counterattack with 45...Be1, but black is also doing fine with Rg6, Kg8, Kh8 or Qb6. |
|
| Mar-26-14 | | BOSTER: <Once > <we dont to be so compliant.>.
First, thanks for analysis.
You are right that black could keeping
an edge.
But I'm sure that Nezh, who could play with two pieces vs the queen, could hold this game. |
|
| Mar-26-14 | | Once: Fritz evaluates the strongest line (45...Be1) at around -4.7. That's considerably more than an edge - it's resignation time. The point is that white has a mass of weak pawns with no way to build a fortress. After 45...Be1 46. Nxg7+ Kxg7 we get this position... 
click for larger viewWhen the attacked white rook moves, black will exchange bishops on b4, leaving black with all five pawns being isolated and/or doubled. Then moves like Qf6 or Qh4 will pick off the white pawns with ease. Fritzie actually thinks that white's best bet is to give up the exchange for a pawn with 47. Rg2+ fxg2 48. Bxe1 
click for larger viewBut frankly that's too grisly for words. Black will play Kf7 and Qf6 and all the white pawns are vulnerable. Not even Nezh could save this one, and I strongly doubt that he would try from a position like this. |
|
| Mar-26-14 | | unferth: <olinart: I think black has a nice counter and gave up too soon. From the position at the end of the game 45:Bb1xe4 .. Bxe4
Qxe4 Qe3
Qxf5+ Kg8
g3-g4 B-d4
Black has a winning attack and White will at least have to give back material.> 48 Rg2 (not g3-g4) stops black's attack in its tracks, and white stays material up with the d6 pawn soon to fall. |
|
| Mar-26-14 | | MountainMatt: Easier than yesterday, at least for me - 44. Nxf5 Nxf5 45. Bxe4 Bxe4 46. Qxe4 Kg6 47. g4 wins back the sacrificed piece plus two pawns and the attack. |
|
| Mar-26-14 | | patzer2: <Once><Life Master AJ> Thanks for the deep computer looks at 42...Nxf4!. Your analysis shows Black is clearly winning after 42...Nxf4! . |
|
| Mar-26-14 | | nalinw: olinart: I think black has a nice counter and gave up too soon. From the position at the end of the game 45:Bb1xe4 .. Bxe4 Qxe4 Qe3 Qxf5+ Kg8 g3-g4 B-d4 Black has a winning attack and White will at least have to give back material. What about
45. ..... Bxe4
46. Qxe4 Qe3
47. Qxf5+ Kh8
48. Qe6
No attack for Black - the Queen has to retreat - and two pawns down. In your line 47. .... Kg8 then Qe6 is also check - forcing an exchange of queens. |
|
| Mar-26-14 | | BOSTER: If black played 42...Nxf4...
But if white played 37.Ne3 not Q f2
<a fascinating line> would disappeared. |
|
| Mar-26-14 | | Cheapo by the Dozen: <olinart>,
After your ... Kg8, White can play Qe6+ forcing a queen exchange. So let's suppose you changed that to ... Kh8. Then White may be able to combat ... Bd4 with a pin on the long diagonal. Even if he can't, Qd3 stops the bleeding at one pawn. Anyhow -- kudos to you for finding what seems to be Black's best defense! |
