THE TACTICS OF CLOSING AND OF OPENING A BOXER
Closing a Boxer to strike him is an effective tactic. “Single Tiger Emerges from Cave” and “Wave Dragon Back to Cave” are useful patterns to brush away a Boxer's attacks and close him.
If it is not feasible to close the Boxer, you can open him by intercepting his attacks. “Immortal Emerges from Cave” is useful for this purpose.
In either case, the Boxer cannot not advance or attack you. His likely choice is to retreat, in which case you chase after him, striking him on the way.
