I (10k) played against white (6k) and unsurprisingly, I lost.
I think that the main problem is that I dealt badly with the invasions and the ensuing fights although I am sure that I made other mistakes that I am not aware of. I would be happy with any advice.
I gave a shot, I’m the same rank as you but I wanted to try reviewing someone else’s game. I didn’t comment on to much of it, hope some of it is helpful.
