I started training with Krisztian in 2013, when I was 11, rated 2120.
Krisztian's training played a crucial role in me achieving my first IM norm in 2013 itself, becoming an IM in 2015, and later a GM in 2016, at the age of 14. I was the youngest GM in the world at the time.
Plus Kristian was always fun to work with. He was understanding, kind and always motivated me.
I only had a couple of sessions with GM Krisztian Szabo due to unforeseen circumstances, but he was always approachable and very flexible with communication and arranging lessons. He is very clear in his presentation, which he delivers in a friendly and cheerful way. I would highly recommend him to anyone interested in improving their chess.
