It seems like you found a nice tactic with the rook sack. Through most of the game you were able to gain control of the position , although I think you hung your knight in the end (which your opponent missed) , and did not directly take the rook after the tactic which allowed your opponent to escape me. However you still secured a W so please take this comment with a grain of salt, for I am quite low rated at the momento (1300 ish) but best of luck w your chess grind :)

It also seems like you still have a relatively new account so I would not be surprised if your rating is fluctuating. Tilts happen to the best of us and I personally think the experience will make you stronger and more motivated to lock back in >:) u got tis

@Zura Javakhadze Thank you so much @Zura Javakhadze for the rec! The PDF sounds great, if you have the copy :) Though, I will definitely look into getting a physical copy.
