OMG I WON AGAINST A CM IN OTB!!

An intense 4 hour battle sitting in the chair alone!! Was very tensed.. My opponent is a very good player from Turkmenistan..(Rank 10) I gathered up the courage to sac my exchange, and my gut told me that this was not a bad choice.. and I went for that move.. I dint have an immediate win though.. But I knew it should give me a good game..(idk how I sometimes thrive in unclear games lol) But how I drew up the courage? From my past games, I figured out the exchange sacs I make, lead to complex position which is usually advantageous to my opponent, but I somehow won all the games!!( 2 games before with higher rateds.. This is the 3rd one)

I was satisfied with my victory today even though the lichess engine gave me a 90% accuracy.. Chess/com engine gave me 89.6%.. But considering the complexity of the position, I think the result was worth it(It gave me 2400 performance tho)
