Chess Mazes #380 There are two types of chess mazes: checking and mating. For bishop, rook, and knight mazes the play is to check the black king. For queen, pawn, and king mazes the object is to checkmate the enemy king; here checks are not allowed. The rules in common for each type of maze are as follows: Black never moves. Only the maze piece (in the case of pawns – the maze units) may move. A maze piece may never move to a square where it can be captured by enemy forces. A maze piece may capture undefended enemy forces. Plus we look for the shortest solution. Helpers in queen and king mazes are frozen to the diagram position, unable to move or be removed. In pawn mazes … [Read more...]

The Marshall – Jaffe Series, Part One
The Marshall - Jaffe Series, February 1909: Win a Match, Drop a Tournament Part One by John S. Hilbert By January 1909, Frank Marshall, considered by most the rightful though unofficial United States chess champion, had been out of the country for nearly twenty months. He returned to New York on the steamer Batavia, arriving Friday, January 8, 1909, after a voyage of 17 days. Marshall's young son, Frank Rice Marshall, turned three during the voyage, on December 28. Eager to see Marshall perform, members of the Manhattan Chess Club, then housed in in the Carnegie Hall Building, were disappointed when the night after his arrival, Marshall's "indisposition" prevented him from starting a … [Read more...]
Outranking by Outflanking
Outranking by Outflanking by Bruce Pandolfini In the opening, when you flank, you develop a bishop to the side and aim it at the center. In the endgame, when you outflank, well, you don't do the opposite. That is, you don't develop a bishop to the center and aim it at the flank. Good old endgame. It's full of all kinds of themes and fancy names to designate those themes. The concept of outflanking: that's a military term in real life, but what's it got to do with chess? Chess experts and theorists seem to use it in slightly different ways. Nevertheless, for many endgame enthusiasts, outflanking tends to refer to maneuvers by which one king, primarily using the opposition, is able to … [Read more...]

The Dude Abides
The Dude Abides by Jeff Coakley February is artist appreciation month at the Cafe gallery. Currently on display is a selection of fine work by one of the great puzzle masters of all time, Henry Dudeney. ...Our lives are largely spent in solving puzzles; for what is a puzzle but a perplexing question? And from our childhood upwards we are perpetually asking questions or trying to answer them." Henry Ernest Dudeney (1857-1930) worked most of his life as a civil servant in Sussex, England. But he made his mark on the world as a mathematician and composer of puzzles. His early creations were published in various newspapers under the pseudonym "Sphinx". He also collaborated for … [Read more...]
Make Your Own Database
Make Your Own Database by Bo Bredenhof During the weekends I set aside some time now and then to build myself a new up-to-date database (DB) for CC searches. I seldom use a DB package, outside of what comes bundled with other software, but make my own every few years. Maybe it is because I am stubborn; or more likely because I want to create something myself. This time I started with the best chess engine DB I had: the Houdini4 Pro DB from 2013. It contained games from late fall 2012. In order to update the OTB part of it, I went to the website "The Week In Chess" (TWIC). They are kind enough to have an archive of weekly OTB files covering all important games played in tournaments … [Read more...]
The Immortal Quiescence Error Game
Novice Nook #163 The Immortal Quiescence Error Game by Dan Heisman Quote of the Month: Quiescent is quiet - there are no more forcing moves of consequence. In Quiescence Errors we examined the very frequent mistake of stopping analysis too soon. A most common example is a missed pseudo-sacrifice (some call it "sham sacrifice") combination which starts with giving up material but soon gains it back - and more - by force in the next few moves. One reason why amateurs get problems they see in books but miss those same combinations in games is that they start with a pseudo-sacrifice. In a problem the reader, if he is a lower-rated player, has the implicit instruction "Keep looking! … [Read more...]
Tarrasch’s Tempo
Endgame Corner #161 by Karsten Müller Tarrasch's Tempo Ronald Wieck wrote in to say, "I believe you will be interested in a discovery by IM Bernard Zuckerman." Of course I was very interested, as an old and famous rook ending was concerned. He had talked to Bernard Zuckerman on the phone: "Bernard and I were talking about rook endings and right before we hung up, he asked me if I was familiar with Rubinstein's draw with Tarrasch at San Sebastian, 1911. Proudly, I announced that I was. He pressed on with, "but did you ever wonder what happens if Tarrasch gains a tempo?" And indeed Zuckerman, who did not use a computer, seems to be right. Tarrasch could have won: 161.01 … [Read more...]
The Return of Robert James Fischer!?
Inside Chess, 1992/16 The Return of Robert James Fischer!? by Yasser Seirawan Fischer Signs for Match in Yugoslavia Sensational news reports from Belgrade, Yugoslavia confirm that the legendary chess player Robert James Fischer – winner of the 1972 World Championship match has signed a contract to face Boris Spassky in a rematch. Wow! What is one to make of this report? First, a little personal history. I was born March 24,1960. A Child of the Sixties, as it were. It was this generation – born into the "Age of Aquarius" – that was supposed to right the sins of the previous generations. A heady responsibility to be sure. Nonetheless, this generation grew up fully expecting to … [Read more...]
Alekhine’s Whammy
Alekhine's Whammy by Jeff Coakley Besides a full round of double whammies, this column features a detailed analysis of Fortis-Alekhine 1925, the most famous game of Marseillais Chess ever played. "Double whammy" is another name for a series-mate in two. These are the special instructions. a) White plays two moves in a row to mate Black. b) The first move may not be check. c) Either move may be a capture. d) Both moves may be with the same piece. e) Black does not get a turn. f) White may not place their own king in check on the first move, even if they get out of check with the second move. If you haven't experienced the whammy before, here are a couple easy ones to get you … [Read more...]
