What should I do? link of the game
I could see that you made at least 3 unnecessary moves that are not the best in the opening and allowed the opponent counter-play. In order to have a better understanding of the positions and the opening, please watch: Section 2 - Anti-Sicilian 2.Nc3, Part 1 (2...d6) of the course:
And when you have finished and understood the move order and positions that you are going to get, if you still need more instructions, please watch the course:
After that, please go back to your game, check it yourself and post here in this same post, what was wrong with your game. We can comment on that after you have done your homework. I am sure that you will find it out very fast after watching the courses!
Happy learning!!! Enjoy!!!
