To win need to focus on doing things properly, not on winning.
If a person focuses on winning they do not do things properly and so not win.
Focusing on winning makes a 101 things go wrong. The person gets stressed, rushes things, works through strength and not skill, not have right mental view and so on.
The person does not worry and so focuses on exactness.
So need to focus on doing things properly and let the technique guide you through to winning.
This is is the same for all things, fighting, building a business etc.
In Zen this is called focusing on the job and not the reward. The person’s thought, focus and energy goes into doing the job and is not wasted dreaming and thinking about the reward. So the person is 100% efficient.
