|Aug-19-05|| ||EmperorAtahualpa: 16...cxd4 would be a lot better. Nice puzzle!|
|Aug-19-05|| ||who: My understanding - though possibly incorrect - is that copying 0.5% of a book is not an infringement on copyright. If it is then I am sorry for posting the analysis. http://www.umuc.edu/library/copy.html says it is legal to copy a chapter for instructive putposes, and this is much less than that.|
|Aug-19-05|| ||jahhaj: <who> That's interesting information. 'Fair use' allows much more than I imagined.|
|Aug-19-05|| ||HastyMover: I didn't get this one. I looked at 35. c4, but figured that the response ... xc4 just lost a bishop for white. After knowing the answer, I tried to go back and figure out why black wouldn't have just taken the bishop back.|
I realized afterwards, that if ...xc4, then 36. xd7 xd7 37. xf6+ h5 (forced) 38. g4+ h4 (forced) 39. h6#
It's amazing how much easier these puzzles are once you look at the answer.
|Aug-19-05|| ||patzer2: Tal's <35. Bc4!> solves today's daily puzzle by cleverly combining the pin and deflection tactics.|
If instead of the move played, Black had captured the "en prise" Bishop, play might have continued 35...Bxc4 36. Rxd7 Qxd7 (36...Qe6 37. Rxa7 ) 37. g4+ Kh4 38. Qh6#.
Interestingly, if the game had continued, Black would have faced the same fate after <36... Qxf5> (36... Bxc4 37. Qxc6 ) <37. Bxe6> Qxe6
(37... Qxf3 38. gxf3 wins a piece) 38. Rxd7 Qxd7 39. Qf6+ Kh5 40. g4+ Kh4 41. Qh6# 1-0
|Aug-19-05|| ||RonB52734: <who> and <jahhaj> I apologize in advance for a lengthy post on copyright law. I'm leaving out blank space to minimize the intrusion space-wise. Beware. "Fair use" is unpredictable in new situations. It depends on a multi-factor "balancing" test and unlike a speed limit you never know how the judge in the next case is going to react. The factors include: the identity of the copier and his reasons for copying (education and analytical discussion are good, but profit is bad); the extent of the copying (a chapter can be ok IF the other factors favor you and if the book you're copying isn't only a 2-chapter book!); and the number of copies (a classroom is good; the whole chess-loving Internet is bad bad bad). Note that the information on the website you linked to is talking about copying things for a single class at a single school. I do think it is "fair use" for members, like <who>, to quote from a book's game analysis once in a while. (And of course it is greatly appreciated.) But I seriously doubt whether the same conclusion would apply if cg.com absorbed the same text into the annotations for this game. This is because cg.com could arguably be said to be profiting from the use, whereas <who> could not. We now return you to our regularly scheduled program.|
|Aug-19-05|| ||patzer2: An alternate winning solution, combining the deflection and passed pawn tactics, is 35. h4! Kg7 (35... gxh4 36. Qe3+ Kg6 37. Qxa7 ) 36. hxg5 Rxb7 (36... fxg5 37. Qe3 ) 37. axb7 Qxb7 38. Qxf6+ .|
|Aug-19-05|| ||who: One of the things I like about Tal's book is the way he talks about plausible moves that lead nowhere. In his discussion of various moves in the Benoni he talks about moves that were made, which he doesn't criticize, but end up leading nowhere. Similarly, in this game he talks about Dvoretsky forcing him into complications, but it turns out that they favored white. It was not that Dvoretsky showed poor judgement in pushing for complications. I feel annotators too often use hindsight to judge a player, but sometimes even the best minds don't really know if a move they are making is right or wrong. Only trial and error can show that.|
|Aug-19-05|| ||ThomYorke: <I Pawn You> Easy puzzles? I have to say that today´s puzzle is not that easy. If you´re saying that is cause you didn´t calculate every combinations.
I learned too much solving this "easy puzzle".|
|Aug-19-05|| ||Robin01: I failed to find the correct continuation today. It was not easy.|
|Aug-19-05|| ||The King Returns1: I agree with Who. Who, you may ask? Who.|
|Aug-19-05|| ||al wazir: <who: My understanding - though possibly incorrect - is that copying 0.5% of a book is not an infringement on copyright.> Correct. The term for that is "fair use." You can't copy a book for your own commercial purposes, but since your excerpt will probably cause sales to spike, you actually did the author and publisher a favor.|
|Aug-19-05|| ||trumbull0042: "In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include --|
1. the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
2. the nature of the copyrighted work;
3. the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
4. the effect of the use upon the potential market for or value of the copyrighted work."--Section 107 of the Copyright Act of 1976.
|Aug-19-05|| ||kevin86: This is a good puzzle,based on a double deflection: 35...xc4 36 xd7 xd7 37 xf6+ and mates. The bishop is deflected from d7-the queen from f6!|
Tal wins another brilliant one!
|Aug-19-05|| ||who: <trumbull0042> well, |
1) the npurpose wasn't commercial.
3) 0.005 is a small fraction of a work.
4) if people like the annotation they are more likely to buy the book, as I don't think the annotations to this one game are enough to make people feel they already know what the book has to offer.
As for point 2 I am not sure what that means. In any event, I think it is fairly clear that it was legal for me to post the annotations, and I was/am hoping people would actually look at them and comment on the game!
|Aug-19-05|| ||patzer2: Perhaps Fritz 8's suggestion 13... Nfd7 14. Nxe5 (14. Nh2 Nb6 =) 14... dxe5 15. Be3 Nc5 16. Bf1 Ne6 = would have kept Black out of trouble in this game. Then again, against Tal, who knows what might have happened?|
|Aug-19-05|| ||al wazir: <who>: 1. You're in the clear.|
2. We wouldn't turn you in even if you weren't. We're your friends.
3. And if we did, the FTC would say, "You want us to press charges against who?"
|Aug-19-05|| ||scottnewhouse: Here is a good alternative which no one has looked at: 35. Rxd7 Bxd7 (Queen can't take because of 36. Qxf6+) 36. h4 gxh4 37. Qe3+ Kg7 38. Qxa7 and White will win the Bishop and Queen the a-pawn. Seems like with this the Queen can find some other way to remove the a-pawn. I believe Black's best move in this line is 36...Bc8 but it still allows 37. Bc4 Qg6 38. Qe3 Qg7 39. hxg5+ fxg5 40. Qc5 and another Black pawn will fall. Of course this is all moot as Tal's solution is better and quicker to win.|
|Aug-19-05|| ||al wazir: <scottnewhouse: 35. Rxd7 Bxd7 (Queen can't take because of 36. Qxf6+) 36. h4 gxh4 37. Qe3+ Kg7 38. Qxa7 and White will win the Bishop and Queen the a-pawn.> 36...gxh4 isn't forced. Black can play, e.g., Kg6 instead. Then if 37. hxg5 fxg5 38. Qxf7 Kxf7 no pawn can promote. If 37. Qe3 then 38...Be6, defending the a-pawn. But black's situation is perilous, with weak pawns everywhere, so I think white eventually wins.|
|Aug-19-05|| ||snowie1: I found Bc4, but f5 threw me off a bit, but I would have continued with Bxe6...Qxe6 (can't ignore any longer) Now....Rxd7!...Qxd7 And the music...
Qxf5!!! There is no way for balck to ignore the move..when Qf6 +..Kh5 and g4+ Kh4 followed by Qh6mate..but if black takes; Qxf5 exf5 and black will not stop d7...d8=Q, etc.|
|Aug-19-05|| ||Sneaky: Good puzzle.
This puzzle is hard in the way that some composed problems are hard. When you look at it you notice that you have Qh5+ whenever you want to play it, but unfortunately it doesn't do anything. So you naturally try to think of ways that you can force a position where Qh5+ would be a winning move.
Of course, this whole line of reasoning is a dead end. You'd have to trick Black into putting a piece on g7, but there's no way to do that, so Qh5+ is good for nothing. But the patzer in you is saying "A check is a check! You can't checkmate without a check!" And so you are loathe to play any move which gives up the one resource you have on the board, Qh5+. Of course, the winning move is do exactly that, abandoning the worthless Qh5+ for the crushing Qxf6+.
|Aug-20-05|| ||scottnewhouse: <al wazir>After 36...Kg6 then White can work himself to the other side this way: 37. hxg5 fxg5 38. Qh5+ Kf6 39. Qh6+ Qg6 40. Qf8+ Qf7 41. Qb8 and black loses the a pawn. I have to admit, however, that I missed this at first. Black's position by move 35 is completely lost and it seems like White has many options at his disposal to finish off Black. The beauty of Tal.|
|Aug-20-05|| ||Richard Taylor: My idea was 35. Bc4 then if B:c4 36. R:d7 Q:d7 37. Qf6+ Kh5 38. g4+ winning. Or 35. Bc4 Kg7 36. Qh5! (of course Tal's line is easier) Q:h5 37. B:e6 and Black wins - 36. Qf5 looks winning also but if say 35. ... Kg6 36. Qf5+ B:f5 37. ef5+ Kg7 38. B:f7 R:f7 39 d7|
I actually missed 35..f5 as a defence - stupid of me -
when I saw it I saw Tal's line of taking on c6 but I wondered also if 36 Q:f5 also wins
|Mar-20-11|| ||Llawdogg: Wow! 35 Bc4!! That was a brilliant move. I wonder how long it will be before I could ever see something like that over the board. This is an amazing game.|
