## Sinamban chessPresentation Transcript

• CHESS For MAPEH IV MR. RODEL E. SINAMBAN, MAPEH III-IV Teacher Jocson College, Inc., Angeles City
• Names of pieces
• K – King
• Q – Queen
• B – Bishop
• R – Rook
• N – Knight
• pawn has no letter
• THE BOARD and SETTING THE BOARD Ranks (1-8) Files (A-H)
• The moves of the pieces
• How moves are indicated
• First write the letter of piece to move, then its destination square
• Ex. Ke2 means “King moves to square e2”
• Note that pawn has no letter, so just write only its destination square
• Ex. e4 means “pawn to e4”
• Capturing (“x”)
• Letter of piece, followed by “X”, then destination square
• Ex. Kxe2 means “King captures on e2”
• Check “+”
• Add suffix “+” to piece giving the check
• For example, Qe5+ means “Queen moves to e5, CHECK.”
• Ambiguties
• If two alike pieces can move to same square, then must differentiate by rank or file
• Ex. Rooks on a1 and f1 can move to common square d1, and we want to move rook on a1
• Lie on same rank 1, but on different files a and h
• Thus use file letter to differentiate – R a d1
• Play and the Object of the Game
• Drawn Game Castling En Passant
• The Pawn can perform a special capture called &quot;in passing&quot; (en passant , from French ). This move should be made immediately after an opponent moves a Pawn two squares forward from its starting position and an opposing Pawn can captured it as if it had only moved one square forward (Fig. 9 & 10). It must be done on the very next turn or not at all by making another move and losing the right to do so. All Pawns on their initial position and two square move option are subject to this capture. Such a move is the only occasion in Chess in which a piece captures but does not move to the square of the captured piece. Black Pawn just moved two squares to e5 enabling the white Pawn to capture it by placing itself at e6 and removing the black Pawn from the board
• En Passant
• En Passant
White Pawn just moved two squares to e4 enabling the black Pawn to capture it by placing itself at e3 and removing the white Pawn from the board
• Pawns can only capture in a diagonal way as shown in Fig. 6 & 7. When a Pawn (white or black) places itself in front of any friendly or enemy piece, it cannot move forward or capture such piece. The Pawn cannot move to the red &quot;X&quot; as shown in the graphics below since it is an illegal move. White Pawn moves and can capture the black Pawn Black Pawn moves and can capture the white Pawn
• When any Pawn white or black reaches an 8th rank square (white piece) or 1st rank square (black piece), it can be promoted to any desired piece of their same color other than King or Pawn (Fig. 8). This is done by removing the Pawn from the board and placing the wanted piece on the reached square. The Queen is chosen as a natural and logic move for it's the most powerful Chess piece. White and black players can promote to any higher piece
• Tournament Play
• In high level play, you will be required to write down your moves.
• Number each move when you write it down. A move actually consists of two parts: a move from White and a move from Black.
• Thus if both players move their King pawn two squares forward on the first move, it would be written as 1. e4 e5.
• Example
• The Pin
• The most commonly used tactic in chess
• Entire chess games have revolved around the pin
• creation
• threat of creation
• prevention
• What is a pin?
• Definition – a simultaneous attack on two pieces on a straight line, one directly and one indirectly
• The less valuable piece is in front of the line, and attacked directly
• “ pinned piece”
• The more valuable piece is in back of the line, and attacked indirectly
• “ shielded piece”
• If the front piece were to move, the back piece would be exposed to attack
Pinned Shielded
• Only pieces that move in straight lines can pin
• Rooks, queens, bishops
• Bishops are the most commonly used pinners, since they are worth less than the others
• Two kinds of pins
• Absolute – the shielded piece is the King. The pinned piece cannot move, as that would expose the King to check. The most powerful type of pin.
• Two kinds of pins
• Relative – the shielded piece is anything other than the King. Although pinned, the pinned piece can still move and attack just as any other piece, only at the cost of losing the shielded piece.
• Example of “piling up”
• Two common pins in practice
• Bishop to g5, pinning knight on f6 to queen
• Two common pins, cont.
• Rook to e1 after castling, pinning piece on e-file to enemy King
• What to do if you are stuck in a pin?
• Attack the piece causing the pin
• What to do if you are stuck in a pin?
• Block the line of attack with another unit
• What to do if you are stuck in a pin?
• Move the pinning piece out of harm’s way and counterattack with a greater threat, such as a check (only works with relative pins)
Nxe5! Bxd1 Nxf7+ K moves Kxd1
• The Double Attack
• What is a double attack? An attack on two pieces, using either one or two pieces in tandem
• Many moves can be considered “double attacks”
• Single-piece double attack
• Fork
• Discovered attack
• Two-piece double attack
• Discovered check
• Skewer (inverted pin)
• The Double Attack is usually the deciding blow in chess, as it usually threatens checkmate or the win of material
• Pins can create pressure, but double attacks win the game!
• Two Types of Single-Piece Double Attacks Fork Skewer
• Fork – the most elementary of double attacks
• A direct attack on two pieces at once, using one piece
• Knights are best suited for forks, since they cannot be counterattacked by other pieces than themselves
• Queens are also great for forks due to its long wide range
• Skewer (inverted pin)
• Two pieces are attacked on the same line, but the more valuable one is in the front of the line
• When the front piece runs, the rear piece is exposed to attack, and subsequent capture
• End!
• Setting up
• Oftentimes your opponent will not allow himself to be forked or skewered so easily! Thus you must set up the position so that you can deliver the fork or skewer
• How? Use forcing moves , such as checks and captures to force your opponent into a fork/skewer situation
• Fork set-up
• Skewer set-up
