Also, if your opponent makes a move that does not save their king but they could have, you are not aloud to take their king, they must move back and play a move to save their king. Below are a few examples of checkmates. I have left off the opposing kings in the following examples because they are not important in the mating position. White's rook on b7 blocks off all the flee squares of the king while the other rook delivers the check and covers the remaining flee squares, white wins. This one is a little different.
Black queen delivers both the check and cuts all the flee squares.
White can't take the queen because it is protected by the bishop, so if he took, black would just take his king. Now you know what the object is and are ready to move on to some other rules of the game as well as some interesting cases that I've left until now so that you'll better understand it. After, you'll be able to take a look at some chess strategy and be able to go show all your friends what you've learned. Let's go to part 8.
