So what happened was that i was black and we did our game ok? So what ended up happening was that the white king came to a5 and he was trapped there as i moved my knight to cut off his moves and he couldn't attack any of my pieces as a queen cut of where he could go. So he was stuck. He tried to get his pawn to turn into a queen and then i moved my pawn without him seeing it and i checked him but it was actually a checkmate and I got the killer pawn achievement. Is this checkmate hard or not. If it is hard please tell me how hard it is

spam here i'll like them all

Besides caro-kann which everyone ik has been recommending me can i have some good openings for black?

Can someone give me good openings to counter caro-kann because whenever im white i can never get past it

Out of the 5 games I played, I lost 1, you are everything to me! (Virtually)
