| Mar-17-12 | | BOSTER: Honestly, I have to explain what helped me to find the correct moves order in this not very easy solution: If Duras could find it (I hope) , I have to . Believe me this is an excellent stimulus, and certainly , the back rank weakness and the open file for f8 rook support my decision. 22...Qe3+ 23.Bd2 Qxd2+ 24.Rxd2 Rf1+ 25.Rd1 Nb3+ 26.cxb3 bxb2#. I guess you need the great imagination looking at <POTD> see the final position. |
|

 | | ajk68: A possible variant is Qe3+ Bd2 Nb3+ cxb3 Bxb2+. I haven't run it through a computer but I think it leads to mate no matter what white tries. |
|

| | doubledrooks: I transposed moves from the game line, but it still seems to be mate in five: 22...Qe3+ 23. Bd2 (23. Rd2 Re1#) Nb3+ 24. cb Qxd2+ 25. Rxd2 Rf1+ and now: a. 26. Kc2 Bb1#
b. 26. Rd1 Bxb2#
I confirmed this with Crafty. |

| Mar-17-12 | | mikmik777: Black to play: 22. ...?
(Vitacek vs Duras)
"Very Difficult"
Black has a very nice position. He has complete control of the e-file using the queen-rook battery. Black also has influence on the open f file, a2-g8 diagonal, and a1-h8 diagonal. Also, Black's knight is well placed in the center. Although his king is quite exposed, it's not currently on immediate danger.
White, on the other hand, has 2 pieces undeveloped at g1 and h1. His king has a cramped position on the queenside.
I managed to calculate the resulting variation:
22. ...Qe3+
23.Bd2
(23.Rd2 Re1 mate; 23.Rd2 Rf1 mate)
23. ...Qxd2+!!!(Sacrifices the queen but gaining a tempo)
24.Rxd2(forced)
24. ...Rf1+
25.Rd1 Nb3+!
26.cxb3 Bxb2+ mate
I managed to solve the puzzle in less than 5 minutes, owing to the nature of the tree analysis.. Time to check the answer.. Got it right!..:) |

 | | keypusher: Couldn't solve it without touching the pieces. Beautful combination. |
|
| Mar-17-12 | | sevenseaman: <jimfromprovidence> Useful link to Lalic-Khalifman. Black is very aggressive. Do you have a link to the game with Nunn's annotations, may be video link. |
|
| Mar-17-12 | | LoveThatJoker: <Jimfromprovidence> I'm liking <25...Rxa2! 26. Rxf5> [26. Bd3 Bxd3 27. Qxd3 Ra1+ 28. Kc2 Nb4+ 29. Kb3 (29. Kxc3 Ra3+ is even better for Black) 29...Ra3+! 30. Kxa3 (30. Kc4 Nxd3 leaves Black a R up) 30...Nxc3+ 31. Kb3 Nxe5 and Black emerges a piece and two pawns up.] <26...Nb4 27. Kb1>
(27. Bd3 Ra1+ 28. Bb1 c2! and Black wins)
<27...c2+ 28. Kc1 Ra1+> and 29...c1=Q+ is unstoppable  . I'm going to click on the link right now to see if I got it right. LTJ |

| | Jimfromprovidence: <LTJ> <sevenseamen> I'll comment on your posts on that game's page, in order to not to muddy the kibitzes concerning today's puzzle. |
|
| Mar-17-12 | | Crispy Seagull: The position shows a lot of promise for both sides. Too much in fact for me to see through! What a great finish! |
|
| Mar-17-12 | | Memethecat: I started looking at this puzzle almost 4hrs ago determined I would succeed & hallelujah on my 5th stint it came to me . 22...Qe3+ 23Bd2 Qxd2+ 24Rxd2 (this 1st part was there from the beginning)24...Rf1+ 25Rd1 Nb3+ 26cxb3 Bxb2# The strange thing was, on the last time I looked it just all appeared & seemed so obvious, almost Monday like & I couldn't understand why such a simple thing had taken so long. I understand, of course, by that time my mind was so familiar with the puzzle & all the elements, but it ain't happened to me before, hence the exuberance. ^.^ |
|
| Mar-17-12 | | tacticalmonster: very easy: 22 Qe3+ 23 Bd2 (23 Rd2 Rf1#) Qxd2+ 24 Rxd2 Rf1+ 25 Rd1 Nb3+ 26 cxb3 Bxb2# Time spent: 90 sec |
|
| Mar-17-12 | | 5hrsolver: Finally solved this one. Black certainly has the better piece activity. But sometimes there are no guidelines on how to proceed with the attack. You just have to find a way to make your pieces work together. |
|
| Mar-17-12 | | BOSTER: Many generations of chess players enjoy brilliant Duras' combo. But when I see such position (diagram)
click for larger view where black,which rook and queen still on a8 and d8, played 19...Re2 I want ask the question: is this move really strong ,or this is a bluff?
Who will win the game if here white would play timid 20.Qa3?
One line :20.Qa3 Bd5 21.Nxe2 Nxe2+ 22.Kb1 Bxh1 23.Rxh1. |

| Mar-17-12 | | TheBish: Vitacek vs Duras, 1900 Black to play (22...?) "Very Difficult"
I spent some time on this last night, but must have been too tired to solve it. I had looked at the knight sac on b3, but missed the idea of the queen sacrifice first. Obviously, Black needs a series of checks, since otherwise he needs to guard against Qh7# or Qxh8# if the Nd4 moves. 22...Qe3+ 23. Bd2
Forced, since White is mated after 23. Rd2 Re1#.
23...Qxd2+! 24. Rxd2 Rf1+ 25. Rd1
All of this was to clear White's second rank, as well as weaken the b2 square for Black's dark square bishop. Now the mate in 2 should be fairly obvious. 25...Nb3+ 26. cxb3 Bxb2#.
Very well conceived by Mr. Duras! |
|
| Mar-17-12 | | M.Hassan: "Very difficult" Black to play 22...?
Equal in materials
White threatening checkmate on h7
I tried soooooo many differnt lines that none worked and took time as an example: 22.......Nb3+
23.cxb3 Bxc3
24.bxc3 Qe3+
25.Re2 Qxd2+
But in this line white could counter with:
24:Qh7+ Qxh7
25.Bxh7+ Kxh7
leaving two Black pieces under attack (Rook and Bishop). At last, I thought why don't I start with the check by the Queen which could be the most obvious one!! 22...............Qe3+
23.Bd2
<if 23.Rd2 Rf1#>
23...............Qxd2+!
24.Rxd2 Rf1+
25.Rd1 Nb3+
A second bright sacrifice that opens up row 2 for the action of Bishop backed by Rook. 26.cxb3 Bxb2#
I hope I'm right. Time to check |

| Feb-13-14 | | tranquilsimplicity: Duras! Another name to add to Chigorin, Spielmann, Tal, Nezhmetdinov, Bronstein, Keres (in his youth), et al. |

heh... yes, he was as a matter of fact.... |

 | | Honza Cervenka: As it was already pointed out, 20.Bh7+! was winning easily but 21.Rf1! could have decided the game in white's favour. |

 | | offramp: Something was bugging me about the Game of the Day. Finally it struck me: the name of White, Vitacek. It sounds a lot like the title of the world's first gothic novel: <Vathek>, by William Beckford. https://en.wikipedia.org/wiki/Vathek
I have never read that book, and I will never ever ever <ever> read that book, ever. |

 | | Teyss: Another swindle game, good one too. 22...? was a Saturday puzzle in 2004 and 2012 which would seem a bit overvalued by today's standards as CG users are now more familiar with Queen sacs. For our non-native English speaking users, the pun is a reference to "Under duress". Could also have been "Oldrich head on young shoulders". |

 | | OhioChessFan: Pretty nice pun. |
