| Jul-27-07 | | whiteshark: From a review of <Chess is My Life reviewed> by John Donaldson: Korchnoi has his own memories of certain events but no one's can be perfect and certainly not for all the details. When discussing the boycott by Soviet and East European players of certain events he was participating in after his defection, Korchnoi shares some mixed memories on pages 158 and 163. He writes: <' As for the Soviet boycott, its origins were revealed when Romanishin and Yusupov accidentally arrived at the tournament in Lone Pine, when I was already there. A multi-stage exchange of telegrams and letters were required and finally the central organ of power in the USSR, the Communist Party, graciously allowed the Grandmasters to participate side by side with me in the tournament. These documents were redeemed by me from the office of he Communist Party Central Committee in 1994.'> The actual story, which I [Donaldson] remember because I played at Lone Pine 1981, and confirmed with published accounts of the time, is Yusupov and Romanishin arrived in Lone Pine on the bus from Los Angeles International Airport with most of the players the day before the first round. There were rumors but no Korchnoi at the players meeting that evening, but the next morning he miraculously appeared. He had arrived at 1:45 in the morning on a Greyhound bus from Los Angeles and was lucky to run into the tournament travel coordinator Jerry Hanken, who was having a late night blitz session with fellow Master James Thinnsen. Hanken tried to get Korchnoi a room but found that everything was sold out in Lone Pine that weekend due to skiers stopping over on the way from Los Angeles to Mammoth Lakes. Fortunately Jerry remembered that Lev Alburt had a double room and the fellow defector was happy to host Viktor for the night. So Korchnoi was definitely in Lone Pine <after> rather than before Romanishin and Yusupov who were stuck in the middle of things. Korchnoi had called the Soviet government's bluff as it would have looked silly asking its two players to fly all the way back home without playing. As a practical matter there was no Soviet official willing to make a decision on a few hours notice. That was how the boycott was broken <and when Korchnoi and Yusupov played they shook hands. Viktor won a very nice game.>> |

| Dec-12-11 | | King Death: Through an unusual move order, after 10...0-0 is the same position reached in Ribli vs Smyslov, 1983. A good move for White to avoid is 11.e4 e5 when Black is already better as in this game: Bisguier vs Smyslov, 1955. This was a nice combination by Korchnoi to end his first tournament game
with a Soviet player after his defection in 1976. |
|
| Dec-19-11 | | Nemesistic: This is a really neat little game,that Korchnoi finishes off cleverly .. 37. White to move would make an excellent Wednesday/Thursday puzzle. |
|
| Apr-19-12 | | lost in space: This is what I got:
37. Rxf6! Kxf6
(Alternative: 37...Rc4?! 38. Bxc4 (or 38. Bc3 is looking every interesting but too complicated for me this morning) 38...Qxc4 39. Qxc4 Nxc4 40. Ra6 with decisive material plus white) 38. Qd4+ Kg5 39. Be7! Qxe7
(39...Kh6 40. Qh4+ Kg7 41. Qf6+ Kh6 42. Bf8+ Kh5 43. g4#) 40. Qf4+ Kh5 41. g4+ Kh4 42. Qh6#

|
Apr-19-12
 | | al wazir: I think 37. Rxf6 Kxf6 38. Qd4+ Kg5 39. Bd6 (my move) also works. If 39...Rc2+, then 40. Bxc2 Qxc2+ 41. Kf3 Qc6+ 42. Kg3, and black is out of checks. If now 42...Nd5, then 43. h4+ Kh5 (43...Kh6 44. Bf8+ Kh5 45. Qg4#) 44. Qg4+ Kh6 45. Bf8#. |
|
| Apr-19-12 | | eric the red: what about Rxb6! |
|
| Apr-19-12 | | sevenseaman: Equal.
First thoughts: R sac looks tempting but could be dicey! Some Q moves appeal; 1 Qf4 or 2. Qe8. The idea behind 37. Qf4 is obvious but the one in 37. Qe8 is a bit abstruse. It attacks f7 and ties down the Black Q in defense. (it can be distracted). Million dollars, what do I choose? If the more likely 37. Qe8, what will be the response? 37. Nc4 (good one as it blocks the B and attacks the R but also engenders Rd7). My collected thoughts;
<37. Qe8 Nc4 38. Rd7 Nd6▢> <39. Rxd7 Nxe8> (automatic) <40. Rxc1> and wins  .

|
| Apr-19-12 | | sevenseaman: Hmmm... White went for the more polished R sac (as I suspected) and got a faster win. I had a vague feel for this line but I aint no Korchnoi! Depends on how confident you feel. May be a tad pedestrian, my line will hold for a cool win. |
|
| Apr-19-12 | | shannie: It's fun to work out the lines after 39.... Kh7. |
|
| Apr-19-12 | | M.Hassan: "Medium" White to play 37.?
Sides are equal but White has a Bishop for a Knight. White has the Bishop pairI went through a lengthy line:
37.Bxf7
There could be 3 responses by Black:
A)...Kxf7
B)...Qxf7
C)...Rc2+
A)
37............Kxf7
38.Qe6+ Kf8
39.Rc6+ Be7
40.Rxc7 Rxc7
41.Bxe7+ Rxe7
42.Qxb6
White is left with Q+4p and Black R+3p
Fair to say White wins
B)
37............Qxf7
38.Rxb6 Rc4
39.Qb1 Qc7
40.Rxb5 Qc6
41.Rb7+ Kh8 (not...Qxb7?)
42.Rb8+ Kg7
43.Qb3 Be5
44.Bg8+ Kf6
45.Rb6 Qxb6
46.Qxb6
White is left with Q+B+4p & Black R+B+2p and again is fair to say that White wins C)
37............Rc2+
38.Kf3 Nc4
39.Bxc4 Rxc4
40.Qe8 Qb7+
41.Kg3 Qc7
42.f4 Rxb4
43.Rd7+ Qxd7
44.Qxd7
White is left with Q+4p & Black has R+B+3p fair to say White "likely" wins
Time to check
---------------
AAaaaahhhh! All that hard work and not a bit like actual game! |

Apr-19-12
 | | FSR: 37.Rxf6! Kxf6 38.Qd4+ and now:
38...Qe5 39.Be7+ Kf5 (39...Kxe7 40.Qxe5+ ) 40.Qg4#
38...Kg5 39.Be7+! Qxe7 [39...Kf5 40.g4#; 39...f6 40.Qg4+ Kh6 41.Bf8+ Qg7 42.Qh4#; 39...Kh6 40.Qh4+ Kg7 41.Qf6+ Kh6 (41...Kg8 42.Bxf7#) 42.Bf8+ Kh5 43.g4#] 40.Qf4+ Kh5 41.g4+ Kh4 42.Qh6# 38...Kf5 39.g4+ Kg5 40.Be7+! Kh6 (40...Qxe7 41.Qf4+ Kh4 42.Qh6#, as above; 40...f6 41.Qxf6+ Kh6 42.Qf8#) 41.g5+ Kh5 42.Qg4# |
|
| Apr-19-12 | | WinKing: Lane clearing sacs for the bishops. I am unsure which path Korchnoi might have taken. Both lines seem like they would be ok to play. 37.Rxb6 Qxb6
38.Qe8 <(threatening 39.Qxf7+ & 39.Bf8#)> 38...Rc5 <(seems best)> 39.Qxf7+ Kh6
40.Qf8+ Kh5 <(or 40...Bg7 41.Qxc5 Qxc5
42.Bxc5 & white is winning)>
41.Bxc5 <(& white is winning)> or...
37.Rxf6 Rc4 <(if 37...Kxf6 38.Qd4+ Kg5 39.Be7+ Qxe7 40.Qf4+ Kh5 41.g4+ Kh4 42.Qh6#)> 38.Bxc4 Qxc4+
39.Qxc4 Nxc4
40.Rc6 <(& white is winning)> There are a ton of sidelines in this position & I didn't look at them all. I don't feel all that confident with the analysis I have here & there are bound to be 'holes'. As long as it took me to come up with this my flag would surely have fallen had I been playing this game. Let's check...time to read em' & weep. |
|
| Apr-19-12 | | viking78: This looks easier then yesterday! Material is equal: <37.Rxf6 Kxf6 38.Qd4+> Now if 38...Qe5 lose quickly for Black with either Qxb6+ or the beautiful Be7+!! (Kf5 g4# or Kxe7 Qxe5+ ). So <38...Kg5> (or Kf5 g4 Kg5 is the same) <39.Be7+!>(to deviate Black Queen from defending f4) <39...Qxe7 40.Qf4+ Kh5 41.g4 Kh4 42.Qh6#>. Must be this, then it's my first Thursday in a while, feels good. |

 | | offramp: Korchnoi says that you can sacrifice rooks with abandon - it's minor piece sacrifices you have to really think about. What does he mean by that? God knows. |
|
| Apr-19-12 | | WinKing: Nice thorough analysis <FSR>. |
|
Apr-19-12
| | FSR: Thanks, <WinKing>. |

| Apr-19-12 | | agb2002: White has the bishop pair for a bishop and a knight. All white pieces aim at the black castle. This suggests 37.Rxf6 Kxf6 38.Qd4+: A) 38... Qe5 39.Be7+ Kf5 40.g4+ wins the queen.
B) 38... Kf5 39.e4+ Kg5 (39... Kf4 40.Bd2#) 40.Bd2+ Kh5 (40... Kh4 41.Qf6+ and mate next) 41.Qe3 with the triple threat 42.Qg5#, 42.Qh6# and 42.Bxc1. C) 38... Kg5 39.Bd6 (39.Qg4+ Kf6 (39... Kh6 40.Bh6#) 40.Qd4+ repeat moves) C.1) 39... Qc6 40.Qf4+ Kh5 41.Qg4+ Kh6 42.Bf8#.
C.2) 39... Qc8 40.Bf4+ Kh5 (40... Kh4 41.Qf6+) 41.Qf6 Rc2+ 42.Bxc2 Qxc2+ 43.Kf3 Qd1+ 44.Kg3 h6 45.Qh4#. C.3) 39... Rc2+ 40.Kf3
C.3.a) 40... Qb7+ 41.Kg3 with the double threat 42.Qh4# and 42.Bxc2. C.3.b) 40... Qc6+ 41.Kg3 Rc4 (41... g5 42.Bxf7+ Kh6 43.Qf6#) 42.Bd1+ and mate soon. ------
Another option is 37.Rxb6 Qxb6 38.Qe8:
A) 38... g5 39.Qxf7+ Kh6 (39... Kh8 40.Qg8#) 40.Bf8+ Bg7 41.Bxg7#. B) 38... h5(6) 39.Bf8+ Kh8 (39... Kg8 40.Qxf7+ Kh8 41.Qg8#; 39... Kh7 40.Qxf7+ and mate next) 40.Bc5+ and 41.Bxb6. C) 38... Ba1(b2,c3) 39.Qxf7+ Kh6 40.Bf8+ Kh5 (40... Kg5 41.Qf4+ Kh5 42.Qh6#) 41.g4+ and mate in two. D) 38... Rc2+ 39.Bxc2 (39.Kf3 Qc6+) Qxc2+ 40.Kf3 and White didn't make much progress. ------
I think I'd play 37.Rxf6. |
|
| Apr-19-12 | | whiteshark: What a fine combo by Korchi! :D |
|
| Apr-19-12 | | TheBish: Korchnoi vs Yusupov, 1981 White to play (37.?) "Medium", material even.
I saw the winning idea right away, but it took a few minutes after that to work out the variations from the diagram. 37. Rxf6! Kxf6
The king is drawn out from his bunker, with the surrounding dark squares weakened for White's queen and QB to take over. 38. Qd4+ Kg5
If instead 38...Qd4 39. Be7+! Kxe7 (39...Kf5 40. Qg4#) 40. Qxe5+, or 38...Kf5 39. Bd6, winning the queen due to the mating threats of 40. Qf4# and 40. Qe5# (39...Rc2+ 40. Kf3! Qc6+ 41. Kg3 Kg5 42. Qf4+ Kh5 43. Qh4#). 39. Bd6 Rc2+
Or 39...Qc6 40. Qf4+ Kh5 41. Qg4+ Kh6 42. Bf8#
40. Kf3 Qc6+ 41. Kg3 Kh6 42. Bf8+ Kg5 43. Qf4+ Kh5 44. Qh4#. ~~~~~~~~~~~~~~~~~~~~~~~~~
Drat! I saw the idea of 39. Bd6 Qc6 40. Qf4+ Kh5 41. g4+ (instead of the quicker 41. Qg4+ Kh6 42. Bf8#) Kh4 42. g5+ Kh5 43. Qg4#, but somehow missed the deflection move 39. Be7+! (so I need to work on overworked piece tactics). Would I have seen this in a game OTB? If not at move 37 (working from the diagram here), then I hope by move 39 the bulb would light up! |

| Apr-19-12 | | James D Flynn: 37.Rxf6 Kxf6 38.Qd4+ Kf5 39.g4+ Kg5 40.Be7+ Qxe7 41.Qf4+ Kh4 42.g5+ Kh5 43.Qg4# or 42…..Kxh3 43.Qg3# if instead 40….Kh6 41.g5+ Kh5 42.Qg4# or 38….Kg5 39.Be7+ Qxe7 40.Qf4+ Kh5 41.g4+ Kh4 42.g5+ Kxh3 43.Qg3# or 42….Kh5 43.Qg4# |
|
| Apr-19-12 | | TheBish: Fritzy (that soulless, unimaginative silicon heap dweller) let me know that I missed (after 38. Qd4+ Qe5) 39. Qd8+ (instead of 39. Be7+) with a forced mate in 3, i.e. 39...Kg7 40. Bf8+ Kg8 41. Bh6+ Qe8 42. Qxe8#. Moral: "When you see a good move, look for a better one" - Emanuel Lasker. |

<37. Rxf6! Kxf6>

| Apr-19-12 | | gofer: This is one of those basic "deflection" problems. The black queen is nicely positioned
on c7 defending Pf7, Nb6 and Rc1. But if she was forced to go to b6 then has lost the
ability protect Pf7 and has lost any ability of supporting Rc1 coming back to c8 to
defend. She has also lost a large part of her attacking possibilites along the c file. <37 Rxb6 ...>
Black would like to refuse as going a knight down is preferable to the alternative
of getting mated. But the problem of refusing the rook is that white can then calmly
play Rb7 which causes all sorts of problems, so the refusal really isn't an option. <37 ... Qxb6>
<38 Qe8! ...>
The white queen has invaded the back rank and threatens Qf8#. There is no defense
that doesn't involve death.
38 ... Kh6
39 Bf8+ Bg7 (Kg5/Kh5 40 Qe4 mating)
40 Bxg7+ Kxg7 (Kg5/Kh5 41 Qe4 mating)
41 Qxf7+ Kh6 (Kh8 Qg8#)
42 Qf8+ Kh5 (Kg5 43 Qf4+ Kh5 44 g4+ Kh4 Qh6#)
43 g4+ Kg5 (Kh4 Qh6#)
44 Qf4+ Kh4
45 Qh6#
38 ... Rc8
39 Bf8+ Kh8
40 Qxf7 Rc2+
41 Bxc2 any move
42 Bb3 mating
39 ... Rc2+
40 Bxc2 ...
Black is still about to get mated but is now a whole bishop down! <39 ... Qd8>
<40 Bf8+ Kh8>
<41 Qxf7 ...>
Black would love to play Qe1#, but unfortunately its is only Qe1+... Game over. Time to check...
~~~
Hmmm. I got this totally wrong.
Now all I need is <David 2009> to create a <Crafty EGT> link so I can play this through. Unfortunately, since my recent migration to MS Lync I have had a multitude of issues with IE and reloading Java hasn't helped. With my current problems <Crafty EGT> shoves all the 2nd rank (and higher) pieces further up the board as it generates the position, but keeps the 1st rank pieces where they are, very annoying! I would still like to check whether taking the knight is winning.... |
|
Apr-19-12
 | | paulalbert: Rxf6 and Qd4ch instinctively seemed to me like the right idea, but I can't say that I was able to work out every variation to be sure it was sound. |
|
| Apr-19-12 | | Memethecat: 37Rxf6 Kxf6 38Qd4+
38...Qe5 39Be7+ Kf5 39g4# or
38...Kf5 39e4+ Kg5 40Bd2+ Kh5 41Qg7 mate next
38...Kg5
I gave up here & looked, couldn't see the finish. A lot of work for Thursday, I was going back & forth between 37Rxf6 & 37Rxb6 Qxb6 38Qe8. Both are winning. Korchnoi obviously found the quickest/stylish route. |
