 | | Phony Benoni: Black's queen is protected only by the rook, and it would be nice if we could do something to disturb it. 30.Nc7 comes to mind. Black can't trade queens (30...Qxf3 31.Nxe8+), so 30...Re7 must be played. Then 31.Bd6 Qxf3 32.Bxe7!? and is Black's queen embarrassed? No, she has too many good squares. But that is an idea. Does <30.Nf6> work any better? Black still can't play 30...Qxf3, so <30..Kxf6> and now we can double check and block the rook's path with <31.Be5+>. But <31...Kxe5> and the king protects the queen. But let's go on ... Aha! <32.Qxe4+ Kxe4 33.Re1+> and after a king move <34.Rxe8> forks the bishops, winning a piece back. Sneaky, sneaky! |

| Oct-08-15 | | dfcx: I was looking at 30.Bxh6/Be5+ and not getting anywhere. Then it hit me, the black queen is only protected by the rook, cutting off the connection with e5+ will do the trick, but white needs to draw the king out first 30.Nf6! forking the rook and queen.
A. 30...Qxf3 31.Nxe8+ Kg8 32.gxf3 
B. 30...Kxf6 31.Be5+ Kxe5 32.Qxe4+ Kxe4 33.Re1+ Kf5/Kd5 34.Rxe8 forks the bishops, white has R+B against B+N. |

| Oct-08-15 | | patzer2: In categorizing the playing style of Karpov, https://en.wikipedia.org/wiki/Anato... observes <Karpov's "boa constrictor"[24] playing style is solidly positional, taking no risks but reacting mercilessly to any tiny errors made by his opponents.> Karpov may have preferred solid positional maneuvering over risky tactical play, but this game demonstrates that when the position required it Karpov was capable of dazzling displays of tactical finesse. The initial move in this game's winning combination, which by the way solves today's Thursday puzzle, is a brilliant decoy which utilizes the sacrificial Knight fork <30. Nf6!!> To avoid losing decisive material <30...Kxf6> is forced. Then, Karpov follows up immediately with a second decoy sacrifice, which employs the double discovered check tactical theme, with <31. Be5+!> To avoid mate-in-one, Black is forced to accept a second sham piece sacrifice and play <31...Kxe5.> Karpov finishes off the combination with two more tactical themes. He follows with a skewer attack <32. Qxe4 Kxe4 33. Re1+ Kf5>, and ends it with a winning double attack <34. Rxe8! Be6 35. Rxf8 > (+2.46 @ 23 depth, Deep Fritz 14). P.S.: Instead of trying to exchange Queens with <26...Qg5?!>, allowing 27. Qf3  (+0.61 @ 25 depth, Deep Fritz 14), Black would have been better off with 26...Be6 = (+0.26 @ 24 depth). |

| Oct-08-15 | | ndg2: @CG: this position is certainly wellknown, but it isn't 'medium'! |
|
| Oct-08-15 | | saturn2: I did not know this game, so it was fun to find Nf6
a: ...QxQf3 looses a rook due to the zwischenschach Nxe8+b: ...Kxf6, Be5 Kxe5 and so on looses the exchange due to the awkward position of black's bishops on the 8th rank |

| Oct-08-15 | | morfishine: This was a Friday puzzle (4/23/2004), a Sunday puzzle (11/3/2013) and now a Thursday puzzle. No doubt, in a couple of years, this will be a Saturday puzzle |

| Oct-08-15 | | gofer: The black king can be forced into the open, to defend a fork on
queen and rook.
<30 Nf6 ...>
30 ... Qxf6/Qe7/Qe6
31 Nxe8+
<30 ... Kxf6>
<31 Be5+ ...>
31 ... Ke6/Ke7
32 Qf6#
31 ... Kg5
32 Bf6#
<31 ... Kxe5>
<32 Qxf7 ...>
click for larger viewWhite has given up B+N for a pawn, but positionally black is in real
trouble. The main threat is ...
33 f4+ Qxf4 (forced)
34 Re1+ Qe4 (forced)
35 Rxe4+ Kxe4
So what defensive move can black find in reply to 32 Qxf7???? 32 ... Qf4?/Qf5?
33 Rd5+ Ke4
34 Bd3#
32 ... Nd4?
33 Qxe8+
32 ... Bd6/Be6/Re7
33 f4+ etc
<32 ... Bf5>
<33 Qxe8+ Be7>
<34 g4! >

Hmmm, Karpov played the exchange - which seems a little timid!? <Richard Taylor: Yes even my steam driven Fritz prefers 23. Qxf7 but has anyone noticed that Karpov isn't a computer?> |

|
| Oct-08-15 | | hedgeh0g: A famous game and combination, but always fun to re-visit! |
|
| Oct-08-15 | | nalinw: I am thrilled that I got this - all of it - but probably would never have even thought of it over the board. I actually thought of Laskers famous double Bishop sacrifice where he forks two Bishops at the end when I was visualizing RxR. |
|
| Oct-08-15 | | eblunt: Couldn't black have declined with 30 .... ♕e6/7 and just lost ♖ for ♘, but leaving the ♕s on the board and a less hopeless position ? |
|
| Oct-08-15 | | wooden nickel: Nice game and tactics played by 2 great players... I almost missed the last double attack after 34.Rxe8 not to mention the 32.Qxf7 line, Karpov must have considered it but knew his line was winning.
<morfishine: This was a Friday puzzle (4/23/2004), a Sunday puzzle (11/3/2013) and now a Thursday puzzle. No doubt, in a couple of years, this will be a Saturday puzzle>
As long as it doesn't become a Monday one!
<eblunt: Couldn't black have declined with 30 .... ♕e6/7 and just lost ♖ for ♘, but leaving the ♕s on the board and a less hopeless position ?>
You're probably right, but Karpov would have loved that too! |
|
| Oct-08-15 | | PJs Studio: I saw all of these moves yet didn't see the fork on the two bishops! He's amazing. Karpov and I think nothing alike - he is a genius, I'm a civil servant. |
|
| Oct-08-15 | | Coriolis: My guess was: 30. Bxh6+ Kxh6 31. Qxf7 (with the threat of 32. Bd3 semi-pinning the Queen). Ha ha. Like a wild golf swing, didn't even come close to touching the ball; then staring into the deep distance over the fairway, wondering where the ball was floating.. |
|
| Oct-08-15 | | thegoodanarchist: <FSR: Somehow I'd never seen this before. I got the solution. Beautiful!> Same here, except for the part about getting the solution. Too much for me. |
|
| Oct-08-15 | | BOSTER: With two bishops on c8 and f8 in POTD you can not see that they are innocent, or not.
Of course, Topa should consider that f6 square is very weak, and any piece can go here.
I did not, but he should.
Maybe this is why Karpov had the WC title, but Topalov not yet. |
|
| Oct-08-15 | | psmith: Apparently this was an "insane" Sunday puzzle back in November 2013 (based on earlier comments) but is now a "medium" Thursday puzzle. Have the puzzles been recalibrated? No, I think this is not so hard and I got it in a few minutes... |
|
| Oct-08-15 | | TimothyLucasJaeger: i think if this had been a sunday puzzle i'd probably given up, but eventually (after 5 minutes) i realized that the bishops ended up forked at the end. |
|
| Oct-08-15 | | agb2002: Already over-used. |
|
| Oct-08-15 | | kevin86: I missed this one by a country mile...I was looking at Bh6+ |
|
| Oct-08-15 | | patfoley: That's easy for you to say! |

| Oct-08-15 | | Tiggler: <Hmmm, Karpov played the exchange - which seems a little timid!? <Richard Taylor: Yes even my steam driven Fritz prefers 23. Qxf7 but has anyone noticed that Karpov isn't a computer?>> Well certainly not, and his continuation leads to the faster, surer win, despite the computer evals pointing the other way. After Karpov's continuation we get to, after white move 40, had Topalov played on a little longer:
