Keep two things at mind:
- If you keep winning, victory will loose meaningless. Achieving a Victory is much more rewarding after a few defeats
- It’s a game, focus on having fun more than winning. You mentioned board games, if you see that you won’t really stand much of a chance of victory, why not try that weird strategy you saw online? My last chess match ended up in a complete laughing room after I tried the intercontinental ballistic queen I saw on youtube and somehow ended up loosing both my towers in the process
Also, take a defeat as a way to improve. If you lost, something made you loose, take it as a challenge to improve it
I love the internet
