Although I know it's often useless, I still tend to prefer the "admonisher" approach.
I mean, I go being supportive and encouraging if I see my partners being tensed. However, if I know they could do better but continue to play stupid shots, I tend to remark slightly. I speak up somewhat when I see a better, easier strategy/approach to win. I feel like sometimes partners are too low confident, too wrapped up in whatever that they fail to see/feel easier approaches. How would being quiet in those situations help?
