In the first case the attack must be carried on with sufficient force to guarantee its success. Under no consideration must a direct attack against the King be carried on à outrance unless there is absolute certainty in one's own mind that it will succeed, since failure in such cases means disaster.
A good example of a successful direct attack against the King is shown in the following diagram.
In this position White could simply play Bc2 and still have the better position, but instead he prefers an immediate attack on the King's side, with the certainty in his mind that the attack will lead to a win. (We give, from now on, games and notes, so that the student may familiarise himself with the many and varied considerations that constantly are borne in mind by the Chess Master. We must take it for granted that the student has already reached a stage where, while not being able fully to understand every move, yet he can derive benefit from any discussion with regard to them). The game continues thus:
Another example of this kind.
In the position below the simple move Nxe5 would win, but White looks for complications and their beauties. Such a course is highly risky until a wide experience of actual master-play has developed a sufficient insight into all the possibilities of a position. This game, which won the brilliancy prize at St. Petersburg in 1914, continued as follows:
The student should note that in the examples given the attack is carried out with every available piece, and that often, as in some of the variations pointed out, it is the coming into action of the last available piece that finally overthrows the enemy. It demonstrates the principle already stated:
Direct and violent attacks against the King must be carried "en masse", with full force, to ensure their success. The opposition must be overcome at all cost; the attack cannot be broken off, since in all such cases that means defeat.
