//-->Chess MazesBruce AlberstonChess Mazes is chess. The pieces are the same. They move and capture just the same. Checkand checkmate are exactly the same. But there is one significant difference. The alternationof moves rule has been suspended. That means only one side gets to make moves. That sideis White. Poor Black never gets to make any moves. All he can do it sit back and watch.As a chess teacher I’ve tried out various techniques to develop visualization andplanning skills for my students. The ideal planning situation is where one side gets to make aplan and carry it through without hindrance or interference from the opponent. How do youdo that? Don’t let him move.That’s how Chess Mazes was born. And without realizing it at the time, I had alsoinvented a new kind of chess puzzle.©Bruce Alberston 2005-2015Chess Mazes IntroductionChess MazesIntroduction & Brief OverviewBack to this week's Chess Maze puzzle!ChessMazesBruce AlberstonChess Mazesis chess.

And without realizing it atthe time, I had also invented a new kind of chess puzzle.To do chess mazes it’s assumed that you know:1.2.3.how the pieces move,rules for check and checkmate,chess notation.If you are not familiar with chess notation, don’t worry. Youcan easily figure out how to decipher it from the examplesgiven. So let’s get down to rules. We’ll takebishop mazesasthe sample. This is appropriate since the first maze I evercomposed was a bishop maze.http://www.chesscafe.com/mazes/mazesintro.htm (1 of 14) [11/4/2005 9:42:40 AM]Chess Mazes IntroductionRules for Bishop Mazes (also Rook & Knight)Rule Number One:You are White and yourmaze pieceis the bishop. You canmove that bishop around the board at will or almost at will. Theone restriction is Rule Four. Only the white bishop is allowedto move.Rule Number Two:Black gets a king and some pieces, the number of which willvary from position to position. However, none of the blackpieces, king included, is allowed to move. This makes Black apassive, stationary, observer. He gets to observe the whitebishop as it moves around the board. The one exception is RuleFour.Rule Number Three:The game ends when the bishop places the black king in check.That’s it. Put the enemy king in danger, put him in check, andthe maze is solved. Sound easy doesn’t it?Rule Number FourYou may not place your bishop (mazepiece)on a square whereit is subject to capture by a black unit. You do that, place yourguyen prise,then Black is allowed to move, take your pieceand White loses. You have to start over.Rule Number FiveWe give only the shortest solution in the back of the book. Ifthe maze can be solved inXnumber of moves and it took youXplus one, well, you sort of solved it, but not in the mostefficient manner. You won’t find your solution given.Bishop Mazes in Actionhttp://www.chesscafe.com/mazes/mazesintro.htm (2 of 14) [11/4/2005 9:42:40 AM]Chess Mazes IntroductionNow that you know the rules for bishop mazes let’s see how itworks in practice. We begin with sample position number one.#1You know what you have to do — put the black king in check.The one move that you may not make is 1. Bh6-g7+ .#1aTrue, the black king is in check and it only took you one moveto do it. But you’ve violated Rule Number Four — you putyour bishop in danger, on a square where it can be captured.The black king can just take you off by 1...Kh8xg7. And thatyou cannot allow.So, what can you do? It turns out that you have no less thanfive different ways to solve the maze. Here are the solutions:http://www.chesscafe.com/mazes/mazesintro.htm (3 of 14) [11/4/2005 9:42:40 AM]Chess Mazes Introduction1.2.3.4.5.1. Bh6-g5 2. Bg5-f6+1. Bh6-f4 2. Bf4-e5+1. Bh6-e3 2. Be3-d4+1. Bh6-d2 2. Be3-c3+1. Bh6-c1 2. Bc1-b2+But a problem with five correct solutions is not much of aproblem. What we’re going to do is cut down your options, sothere is really only one way (occasionally two) to solve themaze. If you have too many ways out, then it’s not a very goodmaze. So, here is sample position number one with a slightadjustment.Sample position number two:#2By adding the black knight on f3 we’ve created a whole seriesof mined squares where the bishop may not go to. We alreadyknow about g7, the black king guards it. And the knight takesaway g5, d2, e5, and d4. There are other squares as well but wemention only the most critical. That leaves only one solution,namely1. Bc1and2. Bb2+.#2ahttp://www.chesscafe.com/mazes/mazesintro.htm (4 of 14) [11/4/2005 9:42:40 AM] [ Pobierz całość w formacie PDF ]
