Ruining a great position in my first semi-final

Sort:

I went quickly through the game and was really surprised to see Black's advantage and Black's possibilities to equalise again after losing the advantage. I will come back later

In one line black equalises by sacrificing the quality, quite instructive. Just to tell you: the engine didn't recommend the plan with exchanging the bishops with... a5  and the rook on c8 was the first choice.

I'm no expert(not even close) but your first mistake was 1.f4???
