Chess Illustrations for Technical Chess Terms

The Operation of "Castling" and "Discovered Check."

In this situation (diagram 8) the white King is threatened with what is called "a discovered check," that is, his opponent, by removing the Bishop, would discover check from the Queen, a proceeding in the present instance, which would speedily involve the loss of the game to White. Not being at the moment in check, however, and having moved neither King nor Rook, and there being no intervening Piece between the King and his own Rook, White is enabled to castle, giving check to the adverse King at the same time, and win the game easily, for Black has no square to which he can move his King without going into check, and is consequently obliged to interpose his Q. at K. B's second, or K. B's third square, in either case being checkmated in two more moves, as you will soon be able to see.

The above position represents the appearance of the forces on each side towards the end of a game, and will assist to explain the application of two or three of the technical terms described in the present section, as well as to exhibit the King in a situation of checkmate. You already understand that the moves at chess are played by each party alternately; in this case it is White's turn to play, and he will checkmate his antagonist in two moves. Place the chess-men on your board exactly in the order they stand in the diagram; having done this, suppose yourself to be playing the White men, and take the Black King's Pawn with your Queen, in the manner before shown, i.e., by taking the Pawn from the board and stationing your Queen on the square it occupied. By this act, you not only take his Pawn, but you attack his King, and must apprise him of his danger by calling "check." He has now two ways only of parrying this check. It is clear he cannot move his King, because the only two squares to which he could move without going into check are occupied by his own men; he is forced then either to take the Queen with his K. B's Pawn, or to interpose the Bishop at King's second square. If he take the Queen with his K. B's Pawn, you must reply by playing your King's Bishop (which you will know by the color of the diagonal on which he travels) to K. Kt's sixth square, crying "check." Examine the position attentively, and you will find that Black has no square to which he can move his King, the only vacant one being attacked by your Queen's Bishop, that he has nothing wherewith to take the Bishop that has given check, and neither Piece nor Pawn with which to interpose between it and his King, and that consequently, he is not only checked, but checkmated. In like manner, if, at his first move, instead of capturing your Queen, he interpose his Bishop at King's second square, you immediately take the Bishop with your Queen, who is protected by her Bishop, and say "checkmate."

We append a diagram here, showing a position which has frequently been misapprehended by unpracticed players.

By inspecting the diagram it will be seen that the White King is in check of the Black Queen. By the simple move of the White Rook to K. Kt's 5th square, checking the Black King, and at the same time discovering check by the White Queen, Black is checkmated, although having by far the strongest force of men. We give the position to show that any Piece or Pawn, although employed in covering a check of its own King, has nevertheless the power to check the adverse King.

Perpetual Check.

This diagram will enable you to understand what is meant by perpetual check as well as the most elaborate arrangement of the men could do. Place the men on your chess-board according to the diagram, suppose yourself to be playing the white Pieces, and that it is your turn to move. Your adversary, you will observe, has the advantage in point of force, but this is counterbalanced by the situation, which enables you to draw the game. To do this, you must first play your Queen to one of the three squares where she will check the King, i.e., to K's 4th, Q's 5th, or Q. B's 6th; it is indifferent which, say, therefore, Q. to K's 4th (check). Black has no option, his King cannot move, he must interpose his Queen. If now you were to take the Queen you would lose the game, on account of his two Pawns; but instead of doing so, you play the Queen to King's 8th sq, giving check. The black Queen must again interpose; you repeat the check at K's 4th, Black can only parry it with his Queen, and you may persist in giving the same two checks, ad infinity. In such cases, the game is resigned as "drawn by perpetual check."

Smothered Mate.

This is a familiar example of smothered mate, which you will find can be effected by no other Piece than the Knight. White first move is, Queen to her 5th square checking. Black is obliged to retreat his King to the R's sq., because, were he to play him to his B's sq.K. B's 7th; this brings the King back again to , and affords to White an opportunity of giving double check, which he does by moving the Knight to K. Rook's 6th, checking with both Q. and Knight; as before, the King must go to Rook's sq.; and now follows a beautiful move—White plays his Queen down to K. Kt's 8th (next square to the Black King), giving check; the King cannot take on account of the Knight; he is compelled, therefore, to capture with his Rook, and the Knight then gives the smothered mate at K. B's 7th square.

Stalemate.

Here you observe that White has the great advantage of a Queen against a Rook; but with all this, and the move to boot, it is impossible for him to do more than draw the game. It is evident that he cannot move his Queen from the front of his King on account of exposing him to check with the Rook. If he move his King, Black takes the Queen, and the game is drawn. And lastly, if he take the Rook with his Queen, he places the adverse King in the position before described of stalemate.

Now that you have an thorough understanding of chess terms and knowledge of how the pieces move about the chess board, we will begin to explore the strengths and weaknesses of the chess pieces in the next lesson.
