|Apr-08-13|| ||Travis Bickle: Now that's the way to get a kingside attack rolling!|
|Apr-08-13|| ||Ezzy: <PawnSac: in case you're interested, here's a picture of the early chess clock>|
From <PawnSac's> link -
<By 1883, a mechanical timing device had been invented, called the “tumbling” chess clock. It was first used at a London tournament that year. It was invented by Thomas Bright Wilson (1843-1915) of Manchester, England,>
Invented by a guy from my home city. Didn't know that. You learn something new everyday. :-)
|Mar-26-16|| ||Penguincw: Ooh, I like the pun.
Anyway, a Saturday puzzle here. I correctly guessed 18.Bxh7+ Kxh7 19.g6+ Kg8, and then clicked on the solution, happy to get it, without knowing why it's good and all.
|Mar-26-16|| ||Exploding: I got 18. ♗h7 right, but that is it.
Really I suck at weekend's puzzles.
|Mar-26-16|| ||mel gibson: Difficulty insane?
I saw it straight away!
|Mar-26-16|| ||yadasampati: <mel gibson> Not insane but very difficult. Sundays are insane :-)|
But i am not surprised that you saw it instantly. Our subconscious mind is capable of solving problems without the "traditional" computations of our conscious mind. In this respect, I would like to refer to Daniel Tammet (https://en.wikipedia.org/wiki/Danie...), who can perform amazingly complex mathematical tasks (multiplications, divisions, etc.) within seconds. The solutions just come to him: when he thinks of a number he literally sees a shape in his mind. Combining the shapes in a certain way leads to another shape, that he can associate again with a number, being the solution of the problem ... See "The Boy With The Incredible Brain": https://www.youtube.com/watch?v=AbA...
I am therefore pretty much convinced that our brains are potentially much more powerful than any current day computer

I could see that if the King takes the Bishop white can bring his 2 pawns in & threatens an open file for it's h Rook.
I have won many games like that by sacrificing a Knight in the same way.
Also the Queen can join in the fun after a Knight swap plus
a second Rook!
|Mar-26-16|| ||agb2002: I know this game.|
|Mar-26-16|| ||dfcx: My line agree with the text on the first two moves
18.Bxh7+ Kxh7 19.g6+ Kg8,
but next I choose
20.h6 f6 21.hxg7
and black can't do much to defend its h file.
|Mar-26-16|| ||not not: 21. h6 is brilliant (looks right and feels right); he gives up another piece to rip into king by exchanging pawns (and win his queen); |
did he see it, when he played Bh7, I don't know; fun game to go through though
|Mar-26-16|| ||yadasampati: <mel gibson> Thanks for your reply. I would still recommend to watch the documentary in the second link i gave.|
|Mar-26-16|| ||morfishine: Seen this one|
|Mar-26-16|| ||alfiere nero: Interesting how the puzzle had similarities with today's game of the day.|
|Mar-26-16|| ||patzer2: For today's Saturday puzzle, I figured the relatively unprotected black King side gives White a strong and winning attack with the demolition 18. Bxf7+!|
I duplicated Akiba Rubinstein's first two moves in the combination with 18. Bxf7+! Kxf7 19. g6+, but after 19...Kg8 I deviated from the game move 20. Nxe4! (+3.34 @ 29 depth, Stockfish 100814).
Instead of Rubinstein's 20. Nxe4! , I went with 20. h4 (diagram below):

Here (diagram above) the computers indicate best play is 20...f6 21. hxg7 Qe6 22. Rh8+ Kxg7 23. Rh7+ (+3.79 @ 18 depth, Deep Fritz 15):

From there (diagram above) my move-by-move look with Deep Fritz 15 continues 23...Kf8 (23...Kg8 24. Rgh1 +5.65 @ 19 depth) 24. Rxb7 Re7 25. g7+ Kf7 26. Nxe4! dxe4 27. Rxe7+ (+6.55 @ 20 depth) with a clearly won position.
P.S.: So where did Black go wrong? The computers indicate 17...a6?, allowing the demolition 18. Bxh7+! (+4.69 @ 42 depth, Stockfish 5SE), was the losing move.
Instead, 17...g6 18. Bxe4 dxe4 19. Nh2! (+1.28 @ 26 depth, Komodo 9.42) puts up more resistance.
Early in the opening, instead of 7...b6 8. cxd5 (+0.37 @ 32 depth, Stockfish 6), the computers prefer the popular move 7... c6 = as in M Rodshtein vs M Roiz, 2015 or the slightly less fashionable alternative 7... h6 = as in Harikrishna vs Eljanov, 2014
|Mar-26-16|| ||kevin86: White forces the position open for attack.|
|Mar-26-16|| ||Breunor: I went for 18 N x e4 d x e4 and then 19 B x h7 K x h7 and 20 g6 ch. Does this move order fail (my instincts say it does but I don't' see why.)|
|Mar-26-16|| ||Whitehat1963: What happens if 25...Qe4 or 25...Be4?|
|Mar-26-16|| ||Breunor: I don't have a computer, but I think on 25 ..... Qe4 there is Qd7., maybe Qh5. On 25 ... Be4 there is probably Qh5.|
|Mar-26-16|| ||offramp: I went for 18.Bg6. Does that win?
I was basing it on an old Jon Nunn game.
|Mar-26-16|| ||patzer2: <Whitehat1963> If 25...Qe4, <Breunor>'s 26. Qh5 leads to mate-in-five. The computer pick is 25...Qe5 26. Qxf6 which is good for mate-in-four.|
If 25...Be4, <Breunor>'s 26. Qh5 yields mate-in-five.
<offramp> My computer indicates 18. Bg6 loses to 18...fxg6 or 18...hxg6 (-3.20 @ 20 depth, Deep Fritz 15).
|Mar-26-16|| ||patzer2: <Breunor> Your 18. Nxe4 dxe4 19. Bxh7+ Kxh7 20. g6+ idea wins after 20...Kg8 21. h6 fxg6 [21...f5 22. Qxc4+ (+3.31 @ 18 depth, Deep Fritz 15)] 22. Nh5! (+4.63 @ 37 depth, Stockfish 6).|
|Mar-26-16|| ||offramp: Thank you, <Patzer2>. Back to my drawing board.|
|Mar-26-16|| ||Breunor: Thanks Patzer 2!|
|Mar-26-16|| ||Razgriz: A bit late to the party. Saw the initial 18. Bxh7+, the King would have to take back because otherwise, lets say Kh8 or Kf8, white can just march the pawns down and queen.|
However, it was quite tough to follow up on that. I didn't see clearing up the middle by exchanging knights to allow the queen to barge in.
