| Mar-29-09 | | gauer: A rare example of the Elevator theme occurs above.
In this case, the horizontal pulley mechanism along Queen's Bishop's File, together with a ♖ & ♗ wheel allows for a Vacated square to also become Unguarded, allowing for a Corridor mate, functioning similar to the extraction of a Bucket of water out of a well. Together with King, & Rear Brigadier Rook, a new Command Formation of six men File into Line vs the opposing lone Monarch:

Another Dual 2nd solution also occurs when King & Brigardier are assumed to have not yet ventured from their original posts. Can you, too, execute both methods? One might wish to verify that lonely adversary had not been abandoned for too long, since one of the fifteen Light Infantry captures would have gome something like 0. bxa6+ Kb7->a8, 1. etc. to assure a successful transfer of the initial array to the position in question. Source: recently reprinted by R. Graham in Iron Warrior student newspaper, March 25, 2009, U of Waterloo. P.S. Can anyone provide a name or date to an earlier Composer of this idea, or Distributor to the puzzle, & co-incidental Elevator theme? An initial guess might've been Sam Loyd - without luck finding the diagram within a quick on-line books source check. |

 | | al wazir: <gauer: <one of the fifteen Light Infantry captures would have gome something like 0. bxa6+ Kb7->a8> There are two ways the Shinkman ♙ lineup might have arisen. One way is if black's g- and h-♙s had promoted and then obliging lain down in the path of white's diagonally moving pawn-roller. The other way it could have happened is that by successive captures of white pieces, black's g- and h-♙s could have reached the c- and d- files, where they could have been captured in turn by white's e- and f-♙s on their way to the a-file. White would have had to lose eight pieces in the process (the ♕, a ♖, two ♗s, two ♘s, and two ♙s), so this is possible if white's g- and h-♙s managed to promote and move into the paths of those two black ♙s. |

| Jan-29-13 | | morfishine: I used to work for an elevator company. It had its ups and downs |
|
| Jan-29-13 | | Abdel Irada: For better or for worse, White had to play 20. N1c3. After the text, the game was unsalvageable (much like <morfishine>'s pun). |
|
| Jan-29-13 | | Gregor Samsa Mendel: What happens if White plays 21 Ka1? |
|
| Jan-29-13 | | Abdel Irada: I admit I was in error?
Apparently I'm not calculating very well at present; perhaps sleep is in order. :-S Then again, maybe I can blame it on the pun.... |
|
| Jan-29-13 | | Gregor Samsa Mendel: <AI>--Aren't you in California too? Neither of us are sleeping very well. |

Then again, it's gotten a lot worse since we moved to this hellhole of a town. We're encircled by people we're morally certain are methamphetamine addicts, but of course can't prove it to the satisfaction of law enforcement. In any case, they seem to take turns staying up all night running their dryers with enough fabric softener to be smelled from two blocks upwind. We suspect they're doing this to mask telltale odors, much as traffickers use dryer sheets to hide the odor of their wares. Of course, having been exposed to this crap in such quantities for so long, we're now deathly sensitive to it. And to top it off, these neighbors are well aware of that fact and obviously either don't care or take pleasure in it. (Tweakers are notoriously sadistic, among their other charming features.) I charitably assume they don't really understand the health effects of constantly breathing the gamut of neurotoxins, respiratory irritants and carcinogens they're emitting, but sometimes ignorance isn't much of an excuse. |

| Jan-29-13 | | TechnoGuyRob: <gauer>'s elevator puzzle is impossible to arise during the game. You need 15 white pawn captures to achieve it, meaning black has to sacrifice all 15 pieces. However blacks f,g,h pawns need to also shift in order to be captured, and white does not have enough pieces to sacrifice to achieve this... |

| | al wazir: <TGR: However blacks f,g,h pawns need to also shift in order to be captured, and white does not have enough pieces to sacrifice to achieve this.> No, I tried to explain this. Some of black's f, g, h ♙s could have captured their way over to files c--d, where they in turn could be captured by white's e and f ♙s, while the other(s) first promoted, then moved as pieces over to files a--e to be captured. I think the position could be reached in ~100 moves, but I haven't tried it. |

 | | SwitchingQuylthulg: <al wazir> It can be reached in 34 moves, as shown here: http://timkr.home.xs4all.nl/chess2/... :) |

 | | ajk68: <kevin86>: 1. Kd6 wins in two moves. |
|
| Jan-29-13 | | arnaud1959: The rook must be on f7 instead of f6. |
|
| Jan-29-13 | | Castleinthesky: Unfortunately, this game of the day is not up to par. The pun is not really a pun and white's play is simply poor. He brought the mate more upon himself, than through black's brilliance. |
|
| Jan-29-13 | | TheTamale: Hmm, I think even I would've seen not to take the bishop on move 22, and I have the chess intuition of a brine shrimp. |
|
| Jan-29-13 | | jovack: Fun little finish. Although I'll have to agree with what some of the others are saying, the game felt a bit bland up until white's blunder. |
|
| Jan-29-13 | | Abdel Irada: <TheTamale: Hmm, I think even I would've seen not to take the bishop on move 22, and I have the chess intuition of a brine shrimp.> A "sea monkey" called. He wants his chess intuition back. (He also wants not to be misrepresented as a primate, but that has nothing to do with you.) |
|
| Feb-06-13 | | TheTamale: Abdel, now that you mention it, Sea Monkeys probably had tremendous chess intuition, given the fabulously complex societies they managed to construct. |
