Sharpy has two optimized anti-worker rush patterns available:

1. WorkerCounterAttack
2. PlanWorkerOnlyDefense

Putting either one before your actual defense handler allows the worker rush counter to work without overlapping with normal defense.

One of the most important things in defending worker rushes is to not overcommit. It is critical to keep at least one worker mining so that the opposing bot doesn't get ahead with its worker rush while mining at home.
