The opening method of counting chess:

1, preemptive left-hand approach

This method is mainly to quickly seize three adjacent vacancies on the same line as the diagonal camp in the left corner of our camp, so that as long as there is a vacancy in the diagonal camp, the chess pieces occupying this position can constantly break into the other camp and strive to take the initiative.

2, the left attack method

This method is to occupy the three adjacent vacancies on the left side of our camp, and if there is a vacancy in the other corner, we can occupy the vacancy of the other camp in time.

3. Right-line attack method

This method uses 1, 0, 8 to occupy the three adjacent spaces on the right side of our camp, and then when the other camp has a space, our chess pieces can quickly occupy the space of the other camp with these pieces.
