Although a Chess game differs from a battle in that the material strength of the opponents is equal, the order of events is the same in Chess as in war. The troops are first mobilized and made ready for action with utmost speed, then important positions are occupied which give the troops freedom of action and insure safe lines of retreat and, finally, when the formation of the enemy is known, the strategic plan is made which the generals try to carry out by means of different tactical maneuvers.
