|Jul-06-10|| ||CHESSTTCAMPS: <<Once> So there you have it - the hidden chess number is three. Now all I need to do is work out what it means....> |
I nominate <Once> to write, direct, and star in the first Dan Brown style thriller on chess!
<David2009:> You and <JimfromProvidence> regularly come up with interesting challenges for the forum. Thanks.
|Jul-06-10|| ||TheTamale: D'oh. Took me a few minutes to factor in the pawn at h6.|
|Jul-06-10|| ||I Like Fish: every fish ...
has his day ...
|Jul-06-10|| ||dakgootje: From now on I will no longer try to find the solution for the Daily Puzzle, but instead try to deduce what the subject of <Once>'s story will be.|
|Jul-06-10|| ||WhenHarryMetSally: this one's quite tricky. that black f8 rook is quite pesky and was hampering my efforts at attacking that black king. what to do to get it out of the way? And then it struck me: rg8+! and then follow up with the queen, plus that advanced h pawn allows us to coerce that black pin into a mating position.|
|Jul-06-10|| ||chrisowen: Squids in for white. The octopus knight ring fries black after 28..f5. Sucking up the stretched diagonal hes sushi once Qc3+. It is the long arm of the law see a nice marry of pieces good big finish.|
|Jul-06-10|| ||kevin86: Easier than yesterday's,at least I answered it faster:white clears out long diagonal with tempo gain and mates there.|
|Jul-06-10|| ||YouRang: Quite easy. I noticed 29.Rg8+ right away since it's such an obvious forcing move (29...Rxg8), and then started looking around for a DSB or queen to hit a1-h8 diagonal. |
I found the queen (although a DSB would have been a bit more impressive), and 30.Qc3+ leaves nothing to the imagination.
|Jul-06-10|| ||Patriot: <Once> A very interesting post!|
The puzzle today started with 6 key pieces (Q+N+R+P vs. K+Ph7) and ends with only three (Q+P vs. K) required for mate. So maybe you have a point there about the number 3.
|Jul-06-10|| ||OBIT: <CHESSTTCAMPS>I think <Once> is channelling William Ewart Napier, who wrote the book "Paul Morphy and the Golden Age of Chess". By comparison, <chrisowen> sounds like to me like Napier on hallucinogens. |
Picking a page at random from Napier's book, I come upon the following: "It is a guess, of course, what share of one's chess is original. I am persuaded, however, that 10 per cent is an extravagant guess, and that therefore more than nine tenths of one's play may be credited to analogy -- or, if you like, to background. Cynical philosophy might allow much less, but I prefer the easy theory that the best kind of originality is that which nourishes on a fit appreticeship." Again, that's just a random sampling. Find the book for 288 pages of commentary like this.
|Jul-06-10|| ||scormus: <CHESSTTCAMPS .... Once ... Dan Brown thriller ...> What a brilliant idea!!|
Three. Isnt there a fundamental law of the universe that says that you cannot know the magic number and know what it means at the same time?
|Jul-06-10|| ||BOSTER: All black pieces are standing like mute spectators in this spectacular stage,looking at superclean highway a1-h8 with expectation when white queen will arrive at g7 airport.
29.Rg8+ (clearance sacr.) Rxg8
|Jul-06-10|| ||cjgone: Took me longer than I expected. :o|
|Jul-06-10|| ||dumbgai: Can someone explain why not 17. dxe5, which appears to win a pawn?|
|Jul-06-10|| ||Patriot: <dumbgai> <Can someone explain why not 17. dxe5, which appears to win a pawn?>|
I'm thinking white didn't want to open the f-file, which may weaken f2 at some point. So white decided it more beneficial to allow black to capture instead. White may be able to hold but it looks risky and double-edged. I'm not sure that pawn is worth it. With the game move, white is poised to play 18.d5 with a good game.
|Jul-06-10|| ||Once: <dumbgai: Can someone explain why not 17. dxe5, which appears to win a pawn?>|
Good question. 17. dxe5 is one of Fritz's preferred moves in this position (along with 17. Rad1). They both get an eval of over 1, compared with the move played (17. Be3) which Fritz rates as only 10th best (+0.51).
So I guess it comes down to personal preferences. White might have wanted to avoid 17. dxe5 Nc5 when the knight develops with gain of time. Or he might have wanted to keep the Rf8 underemployed as suggested by <Patriot>. It certainly helps white's attack to have the black pawn on f6. Instead, a grand liquidation of pawns might have led to a rapid exchange of pieces and a draw.
Sometimes good players will play a second best move (or in this case a tenth best) if the resulting position is easier to play.
Apologies if this all sounds a bit nebulous, but I can't see a concrette reason why white didn't take the pawn so we are into the realms of conjecture.
|Jul-06-10|| ||Patriot: <Once>
Well said. My instructor, Dan Heisman, would ask "Does the reward outweigh the risk?" In this case white is guaranteed a pawn ahead so the next question is "How much risk is involved?" For example, 17.dxe5 fxe5 18.Bxe5 (18.Rxe5 Bd6) Qf5 and white's choices seem to be 19.Bf4, 19.Bd4, 19.f3, 19.f4 or 19.Rf2. Quite a few options, actually, which tends to favor white's defense.

Ditto <patriot> - I suggest you activate your personal forum (click Prefs, check Activate your forum, then update profile)
|Jul-06-10|| ||Julian713: Woot, got this one! Slowly but steadily I'm getting better at tactics...I'm rarely missing the Tuesday puzzles now :D|
|Jul-06-10|| ||Patriot: <YouRang> & <zanshin>,|
Thanks, guys! I may have to take a look at the preferences tomorrow to see what it's capable of.
|Jul-06-10|| ||EyesofBlue: Got it, but it took way too long.|
|Jul-07-10|| ||Once: <Patriot> Now that what's I call an avatar! Green with envy.|
|Mar-10-12|| ||edyedzer: Julio Bolbochan was the first argentine chessplayer who played like a truly GM.|
|Jun-25-13|| ||edyedzer: Very nice finish !|
