So guys there’s a chess tournament that I will be participating in soon ,it will happen on the 20th of June ,and I want help preparing for it ,now I’m playing some causal games with the head of our chess federation in Palestine ,I’m rated 2000 + elo online so I’m pretty good but I want help from friends who are good ,better or worse in studying some theoretical lines and famous openings that I’m very sure I will face

Like the kings gambit ,queens gambit ,carro kan ,Sicilian etc

I will be using an account called Red Nablus on Lichess to play and train with anyone who can help me ,we will play unrated games ,960 and normal chess

But you need to know chess to help ,no Cheating

I hope someone here is good at chess ,at least above 1500 elo on lichess or on chess.com

I really want to win this tournament and would appreciate help
