|Nov-28-08|| ||eaglewing: <Mdog> Yes, after 18. ... Kf5 19.Lxe6+ Lxe6 20. e4+ Kxe4 21. Qxe6+ Kxd4 22. 0-0 surviving would be a miracle.|
However, could black have strengthened the defense in this line (Kf5) with 16. ... Ne4? No more 20. e4+ and I see no major advantage / need in Nd5 (it needs to "leave" f6, sure) over Ne4. Extra control over b4/e7 with Nd5 is no big deal, isn't it?
|Nov-28-08|| ||sshhhh: <PolishPentium: Is there any merit in Black counterattacking with 16...Qxg2?> 16...Qxg2, 17. Qb4#|
|Nov-28-08|| ||charms: Very nice pun this time.|
|Nov-28-08|| ||newzild: Looks like 9...Bc8 was the mistake. Allowed the combo on the a2-g8 diagonal.|
|Nov-28-08|| ||Once: Can this really be the same CG that gave us Deepan pizza?|
I had no idea what the "Lorentz transformation", so I scurried away to Wikipedia. And behold ...
"In physics, the Lorentz transformation converts between two different observers' measurements of space and time, where one observer is in constant motion with respect to the other. In classical physics (Galilean relativity), the only conversion believed necessary was x' = x − vt, describing how the origin of one observer's coordinate system slides through space with respect to the other's, at speed v and along the x-axis of each frame. According to special relativity, this is only a good approximation at much smaller speeds than the speed of light, and in general the result is not just an offsetting of the x coordinates; lengths and times are distorted as well.
If space is homogeneous, then the Lorentz transformation must be a linear transformation. Also, since relativity postulates that the speed of light is the same for all observers, it must preserve the spacetime interval between any two events in Minkowski space. The Lorentz transformations describe only the transformations in which the event at x = 0, t = 0 is left fixed, so they can be considered as a rotation of Minkowski space. The more general set of transformations that also includes translations is known as the Poincaré group.
Henri Poincaré named the Lorentz transformations after the Dutch physicist and mathematician Hendrik Lorentz (1853–1928) in 1905. They form the mathematical basis for Albert Einstein's theory of special relativity. They were derived by Joseph Larmor in 1897, and Lorentz (1899, 1904). In 1905 Einstein derived them under the assumptions of the principle of relativity and the constancy of the speed of light in any inertial reference frame."
So now we know. I think.
|Nov-28-08|| ||tivrfoa: why not 14 ... Nc6?|
|Nov-28-08|| ||SuperPatzer77: After 19. h4+, Black's try is 19...Kf5, 20. Bxe6+ Bxe6, 21. Qh5+ Ke4, 22. Rd1! (Setting up the mating net - Black has no defense against 23. f3#) Bxg4, 23. Qe5# 1-0|
|Nov-28-08|| ||kevin86: The final position isn't mate,but it will come soon:|
20...♗xf6 21 ♕xf6+ ♔h5 22 g4#
|Nov-28-08|| ||SuperPatzer77: <Kevin86> You mistyped 20...Bxf6 - Actually it is 20...Bxe6 (not 20...Bxf6), 21. Qxe6+, Kh5, 22. g4#.|
<Kevin86> Oops, you mistyped 20...Bxf6. You must have had a hangover from the Thanksgiving feast. LOL
<Kevin86> I hope you really enjoyed the Thanksgiving feast.
|Nov-28-08|| ||al wazir: <urnebes: Where's the win after 18...Kf5 ? 19.Bxe6+> Ke4. |
Note that black threatens to win the ♕ with ...Bb4+.
|Nov-28-08|| ||SuperPatzer77: <al wazir: <urnebes: Where's the win after 18...Kf5 ? 19.Bxe6+> Ke5.>|
<al wazir> You mean Ke4 (Black King cannot get into e5 because the White d-pawn takes control of e5).
If 19...Ke4, White's best move is 20. Rd1! Nxe3, 21. Bxc8+!
1) 21...Kf4, 22. Qe5#
2) 21...Be7, 22. Bxb7+ 1-0
Chess folks, you overlook Rd1!! - setting up the mating net.
|Nov-28-08|| ||al wazir: <SuperPatzer77>: See my (amended) post: After 20. Rd1, 20...Bb4+ 21. Kf1 (21. Ke2 Qa6+) Nxe3+ wins the ♕.|
|Nov-28-08|| ||cydmd: For 18... Kf5 19.Bxe6+ Ke4 the answer is 20.f3+
20... Kd3 21.O-O-O+ Kc4 (21... Ke2 22.Rd2#) 22.Qa4+ Bb4 or Qb4 22.Ne5#
|Nov-28-08|| ||al wazir: <cydmd>: Thank you for putting the black ♔ out of his misery.|
|Nov-28-08|| ||SuperPatzer77: <cydmd> Well-done!!! al wazir corrected me - a question about 20...Ke4. You made a correct move - 21. f3+! is very simple. It is a lot of better than 21. Rd1. |
21. f3+! lures the Black King into the mating trap. Well-done, cydmd!!
|Nov-28-08|| ||SuperPatzer77: Instead of 20...Ke4, 20...Bxe6, 21. Qh5+ Ke4, 22. Rd1! Bb4+, 23. Bxb4 Qxb4+, 24. Rd2 Qxd2+, 25. Kxd2 - Black cannot avoid the double mating threats of Qe5# and f3#. 1-0|

<whiteshark>, you are priceless!!! Your humor is instantly recognizable, but I still miss your avatar :)
PS. We don't make compound words quite so freely in English: "shortterm" should be "short-term" or "short term", and similarly "longterm". You know what I mean ;>)
All the best...
|Nov-28-08|| ||SuperPatzer77: <whiteshark: This is what a <Lorentz transformation> looks like in your real life : http://sound.westhost.com/counterfe... >|
whiteshark, you're really a pistol!!!
|Nov-28-08|| ||WannaBe: I really wasn't gonna show my 'studly' geekness, but here is the real thing: http://en.wikipedia.org/wiki/Lorent...|
|Nov-29-08|| ||Ladolcevita: <white pawn>
me too,sometimes i am lazy to dig into it,so just let my intuition lead my move....
which i think is the main reason why i scarcely improve in middle game....
|Dec-01-08|| ||Imnotnajdorf: hmm... 9.Bc8 is not a nice move, definitely. But I think that 12 Qb6 is a stronger move than 12.Qb7, black position ´d be far from promising, but at least I think that with 12 Qb6 and then 14.Nc6 they have a glimmer of hope.|
|Apr-16-10|| ||bambino3: 16...Qxg2? 17. Qb4 mate|
|Jun-23-11|| ||Josue Ojeda: Que paliza!!!|
|Mar-08-12|| ||Garech: A blistering attack from Carlsen aged about 12! Great stuff.|
