New Tool

Lately we used a new tool that can be used to create videos to capture the pieces movement. Thanks to caissa's pgn editor . It's a great tool indeed, since it's simple and useful.

Part III: Chess Tactics (Mating-King-Rook)

  • Mating with King and rook

The idea is to suppress the position of the enemy's king using the rook and then moving our king to help the mating.

Let's see the example, white's king is on f4, the rook is on a5, while the black's king is on e7, and it's white's turn.

1. Ra6 Kd7

Here rook is advancing towards black's king to corner him to the upper side. The black counters by moving the king towards the rook

2. Ke5 Kc7

Since the rook cannot suppress the black's king anymore, white moves the king.

3. Kd5 Kb7

If you notice, the white didn't move the king to 6th rank, why? Because we need to make a free space on 6th rank, so that the rook may move freely, moving away from the black's king

4. Rh6 Kc7

The rook moved away from the threat. Once again the black's king tried to move towards the rook. At this point, there will be a moment where white's king and the black's position are on the same file, we need to create that moment, so that we are able to move the rook to the 7th rank, this way the black's king cannot move either on 6th or 7th column.

5. Rg6 Kd7

This is the moment we waited for. After this move, we need to move the rook to g7, after that the black's king have no option but to retreat to upper squares.

6. Rg7+ Ke8

Once again the black's king forced to move to upper squares.

7. Ke6 Kf8

8. Ra7 Ke8

9. Ra8#

This time the black's king cannot move any further and it's a checkmate.

Here's the complete video

Part II: Moving the Pieces (King)

  • The King

The king can move horizontally, vertically and even diagonally but only up to 1 square
Given the king position on e1, what is the possible move?

The answer is d1, d2, e2, f2, and f1

To capture an opponent's piece, first move the queen to the opponent's piece, then take the opponent's piece.

Given the king position on e1, what is the possible capture?

The answer is d1, e2 and f1. Pieces on d2 and f2 cannot be captured as it is being guarded by the knight on d1 and f1.

The king is the only piece that must be protected. The king is checkmated if the king is threatened and cannot move any further.

Note that the king on g1 cannot move to both f1 and h1 as it is threatened by the rook on e1.

The goal of chess game is to checkmate an opponent's king. Once the goal reached, we win the game.


Part II: Moving the Pieces (Queen)

  • The Queen

The queen can move horizontally, vertically and even diagonally

Given the queen position on h1 what is the possible move?

The answer is g1, f1, e1, d1, c1, b1, a1 to move horizontally, h2, h3, h4, h5, h6, h7, h8 to move vertically and g2, f3, e4, d5, c6, b7, a8 to move diagonally

To capture an opponent's piece, first move the queen to the opponent's piece, then take the opponent's piece.

Given the queen position on e4, what is the possible capture?

The answer is all the pieces around the queen, awesome isn't it?

The queen is feared even when she goes alone, that's why some player prefer to eliminate it at the early game.


Part II: Moving the Pieces (Rook)

  • The Rook

The rook can move horizontally or vertically

Let's take an example, given the rook position on a1, what is the possible move?

The answer is a2, a3, a4, a5, a6, a7, a8 to move vertically, and b1, c1, d1, e1, f1, g1, h1 to move horizontally.

To capture an opponent's piece, it must be in the path of the rook movement.

Given the rook position on e4, what is the possible captures?

The answer is d4, f4, e3, e5

The rook is feared when there's two rook in the same rank or file, because they can support each other.

Part II: Moving the Pieces (Knight)

  • The Knight

The knight can move L shaped only.

Given knight position on e4, what is the possible moves?

The answer is c5, d6, f6, g5, g3, f2, d2 and c3.

To capture an opponent's piece, first move the knight to the opponent's piece, then take the opponent's piece.

Given the situations below, what pieces that can be captured by the knight?

The answer is the pieces on f2 and g3.

Knight is feared as it can move through obstacles. Given the position below with black's turn,

Black move the king to d8, then white move the knight to capture the rook on a8

At this moment the black player cannot do anything to stop the white's knight from fleeing as it can move to b6. Remember that the black's king cannot move to c7 as it can be captured by the knight on a8.
