hello ! I've been playing since late 2022 but i stopped during covid due to my online class. Now, we have a tournament in our school tomorrow and I'm currently in the chess club. (because idk other clubs and i dont have talents) I've SUFFERED from mental block during last game due to the timer and pressure of people looking that's why i failed the last tournament. Do you have some tips for me to improve my gameplay and not to have a mental block? also some tips how to start an opening please !! thank you very much !!
