Awesome!
At least for me, getting to 1700 was mostly just experience and practice with what worked for 1600. It was 1800 which was a bit tougher and starting to obtain a deeper understanding of positional concepts.
You may recall my advice for 1600 mostly things like identifying weak squares and outposts. Getting to 1800 rating is deepening this knowledge and adding to it things like studying different pawn structures in mainline openings and maybe even starting to learn about the many different types of pawn levers, significance (or lack of) with pawn majorities and getting much better at converting winning imbalances into a win.
You may remember my 1400-1500 and 1600 plateaus. Well, your advice worked! What to do for 1700?
