Explanation: In the opening the French is what I usually play and this is what I played as black is a system that can be played against basically everything. You have to remember the c6 move to protect your pawn and the rest of the opening moves are where the pieces should be placed. 14. c4 was an explosive move trying to open up the board(did you see what I did there c4 the bomb), but my opponent with the white pieces didn’t realize that when I took the pawn their d4 pawn would be isolated so I did just that. 15. Re7 is a miss(from my perspective) because d5 was allowed and they could get rid of that isolated pawn or make it passed, but me and my opponent didn’t see that. Here in this situation(where I forgot about the isolated pawn) I should have played Nd5 so that the pawn is blocked and I can attack it later. 16. Bg3 the first big mistake giving up a pawn(my opponent is playing well for a 500). Before I played 19. Rae8 I finally remembered that Nd5 is a move, but my opponent played 20. Bc4 which ruined my plan because I would give up a pawn. 21. Nb6 is a good move because I am trying to either trade off my knight for their good bishop or put my knight on d5(I chose to trade with 23. Nxc4 because I would allow pressure on my d5 knight). In the endgame I was trying to trade everything and attack pawns to make them defend, but the 500 couldn’t last any longer and lost a pawn and lost to a fork of their king and queen, but they played well.
