But it is only the Indian game which has had a development equal to the development of the civilized arts. This has been chiefly through what are called by the Italian-French name of _gambits_. There is much prejudice, amongst a certain class of chess-players, against what is called "book-chess," but it rarely exists with players of the first rank. These gambits are as necessary to the first-rate player as are classifications to the naturalist. They are the venerable results of experience; and he who tries to excel without an acquaintance with them will find that it is much as if he should ignore the results of the past and put his hand into the fire to prove that fire would burn. If he should try every method of answering a special attack, he would be sure to find in the end that the method laid down in the gambit was the true one. An acquaintance, therefore, with these approved openings puts a player at an advanced starting-point in a game, inexhaustible enough in any case, and where he need not take time in doing what others have already done. Although we design in this article to refrain, as much as possible, from technical chess, it may be well enough to give a list of the usual openings, and their key-moves. PHILIDOR'S DEFENCE.
