Opening for my first otb?
It's not for fide, It's just a chess tournament between neighbors. The reason I'm asking was to raise my change to win this tournament because there's money if I win this, and I need those money badly.

Thank you for your tips 😊
Openings are not going to decide your games. Openings take years to properly play and understand. Have fun and good luck.

Play whatever you normally play. I played in an OTB Tournament yesterday. Petroff that transposed to an Exchange French (B), Levitsky Attack (W), and Classical Dutch (B), won the first two, drew the third. You don't just change openings because it is OTB.
