Ground which can be freely traversed by both sides is called accessible.
Do not press an enemy at bay.
If their forces are substantial, prepare for them; if their forces are strong, avoid them.
So in war, the way is to avoid what is strong, and strike at what is weak.
The Art of War is self-explanatory
When the higher officers are angry and insubordinate, and on meeting the enemy give battle on their own account from a feeling of resentment, before the commander-in-chief can tell whether or not he is in a position to fight, the result is ruin.
