Before anything else, find YOUR King Make sure you are not in check! Safety first!!
Find YOUR OPPONENT’S King.
1.Identify all of his possible escape squares. (Every square the King could maybe move to.)
2.Identify each of those squares as SAFE or UNSAFE for the King to move to.
3.Looking at the SAFE squares, do they form a LINE or PATTERN? What type?
4.Check if you have a piece that moves like the LINE or PATTERN. Can you attack the square(s) right away?
Squares in RED are NOT SAFE (illegal) for the King to move to.
Square in GREEN is SAFE.
The White Rook and Bishop take away: g7, h8, and h7.
The f8 square is safe for the Black King.
The King’s current square and one escape square form a horizontal line, known as a RANK.
So (a) Does White have a piece that attacks along ranks?
(b) Can that piece attack the rank we are looking at?
2. Outside Forces
Use the same Fundamentals Method. Pay particular attention to pieces that may look out of the game or not close to the opponent’s King.
The Queen is there on that diagonal…it just may take a full look at the board to find her.
A pin is a strategy to keep a piece from moving.
The White Bishop is lined up with the Black King, but the Knight blocks the attack.
But when it comes to moving, if the Knight leaves his post his King would be exposed to check. Which we know is ILLEGAL!
The Knight is pinned onto the c6 square.
The advantage of pins is taking a piece out of play without having to capture it and maybe having to trade one of your pieces to get it.
4. Discovered Check
Discovered attacks come from moving a piece and discovering an attack from another piece behind it.
Moving the Black King to the side…
opens the Queen from behind.
So this would be notated:
5. Double Check
Make (1) move and put the King in check TWICE.
Take this position:
Found the King. Now look to attack…
Check! oh…and Check!!
Regular (single) checks we have 3 way to get out of check.
With double check, the ONLY CHOICE is for the KING TO MOVE!
