A Great Tactic From One of My Games

Hello everyone!

A lot of great tactics happen in chess, and especially in my blitz games, but some stand out more from others. There are some you remember more than others. In a recent daily game I completed, I was playing in a Sicilian Defense themed tournament and had a position where it appeared like maybe I was slightly better, but I wasn't sure since I could not find a way to create a clear plan. But then my opponent made a mistake and I was able to win the game. A second mistake by my opponent, 35 Qd8 helped me to finish the game in style. Hopefully you enjoy this tactic, I thought it was very nice

And there is one more thing. If black played Bf6 instead of Bf8 on move 37 to try and defend, white has another killer tactic, this one I didn't see until analyzing it afterwards with the computer!

I hope you all enjoyed this puzzle! Please tell me in the comments if you were able to solve it and if you did how long it took because I'd like to know for around what rating level the puzzles I am posting are most suitable
