U got lucky tho ur opponent didn't capture the knight during the check machine gun
If you are losing then just start check machine gun.

Right click on a move when ur inserting the diagram
Means I have to write reason behind move.

If you are on mobile, then write annotations in {} brackets and giv space between the move and next move
I am playing black.
I was losing game but then I got chance I used by trump card means checks, when I started giving checks then not stop upto I win or lose.
This technique always work just want one chance.
Last time one person said to add annotations in game so my question is
What is annotations and how to add it?
