Computer says i missed a win there but i can´t find it. Can someone help me please. I am begginer so don´t laugh at me when it will be too obvious please (I am black.)
Yes, there was a smothered mate in 5 starting with Qd4+.
If you play Puzzle Rush a lot, you will learn to spot those.
oh i see, i´ll try it, thank you 
I forgot that the White queen can interpose.
For the OP, this is a pattern worth remembering - and you will definitely launch one of it some day.
Missed mates may depend on the help of the player. There was an open square which, if left open, would have achieved mate.
