Learn a basic endgame checkmate from Elliott Neff When facing a lone king, you should know how to checkmate if you have king, a knight, and bishop. Most videos only show the checkmate when the king is already on the edge of the board. But it is important to learn what to do when the defending king starts in the center. Dribbling is running or moving with the ball under the control of your feet.
Analog game clocks[ edit ] A typical analog chess clock Analog clocks are equipped with a "flag" that falls to indicate the exact moment the player's time has expired. Analog clocks use mechanical buttons.
Pressing the button on one player's side physically stops the movement of that player's clock and releases the hold on the opponent's. The drawbacks of the mechanical clocks include accuracy and matching of the two clocks, and matching of the indicators flags of time expiration.
Additional time cannot easily be added for more complex time controls, especially those that call for an increment or delay on every move, such as some forms of byoyomi. However, a malfunctioning analog clock is a less serious event than a malfunctioning digital clock. Into address the issues with analog clocks, Bruce Cheney, a Cornell University Electrical Engineering student and chess player, created the first digital chess clock as a project for an undergraduate EE course.
For example, the display was done with red LEDs. LEDs require significant power, and as a result, the clock had to be plugged into a wall outlet. The high cost of LEDs at the time meant that only one set of digits could be displayed, that of the player whose turn it was to move.
This meant that each player's time had to be multiplexed to the display when their time was running. InLSI chips were not readily or cheaply available, so all the multiplexing and logic were done using chips that consisted of four two-input TTL NAND gateswhich resulted in excessive power consumption.
Being plugged into the wall is obviously a major drawback, but had one advantage: Each player had a separate counter, and, in a parallel to the original mechanical architecture, one player's counter was disabled while the other's was running. The clock only had one mode: It could be reset, but not set.
It did not count the number of moves. But it successfully addressed the original goals of the project accurate and matched timing. The first commercially available digital chess clock was patented in by Joseph Meshi and Jeffrey R.
Ponsor and sold as the Micromate Time control is commonly used in modern chess in many different methodologies.
One particularly notable development, which has gained quite wide acceptance in chess, was proposed by former world champion Bobby Fischerwho in filed for U. Patent 4, awarded in for a new type of digital chess clock. Fischer's digital clock gave each player a fixed period of time at the start of the game and then added a small amount after each move.
Joseph Meshi called this "Accumulation" as it was a main feature of his patented Micromate US Patent 4, This became the linchpin of Fischer's clock patented 10 years later. In this way, the players would never be desperately short of time. The increment time control was first used in the privately organised Fischer—Spassky matchand quickly became popular in the wider chess world, and was used in the FIDE World Chess Championship Other aspects of Fischer's patent, such as a synthesized voice announcing how much time the players have, thus eliminating the need for them to keep looking at the clock, have not been adopted.
On March 10,a patent application was filed by inventors Frank A. The game timer provides, among other features, a user-definable delay between the time the activation button is pressed and the time that the activated clock actually begins to count down.A chess clock consists of two adjacent clocks with buttons to stop one clock while starting the other, so that the two clocks never run simultaneously.
Chess clocks are used in chess and other two-player games where the players move in turn. The purpose is to keep track of the total time each player takes for their own moves, and ensure that neither player overly delays the game.

My Proposed Thesis. Chess games have chronicled the clashes important to society: the US versus Russia, man versus machine, and royal knights at court. Outside of the realm of a "normal" (or popular game), chess only occurs under special circumstances.
Carrying a custom of formality, two players square off against one another. The Origins of Chess - Medieval Game - Hnefatafl In AD there was a popular game called Tafl or hnefatafl meaning ‘Kings Table’ commonly played in Iceland, .
Chess is a two-player strategy board game played on a chessboard, a checkered gameboard with 64 squares arranged in an 8×8 grid. The game is played by millions of people worldwide.
Chess is believed to have originated in India sometime before the 7th century. The game was derived from the Indian game chaturanga, which is also the likely ancestor of the Eastern strategy games xiangqi, janggi.
