This is an interesting debate.
I think that 1700 chess.com is a bit low to coach 1200-1500, because 1700s have a lot of bad habits and their thinking processes are not so good.
I think a 1700 can coach up to maybe 1200, but higher than that the 1700 is just going to make too many mistakes and thinking process errors to coach effectively.
[ALSO I am 2000 uscf so I know what I'm talking about.. I've seen 1700s make very simple errors lots of times]
@pipking get off your cp and get a job instead of scamming noobs
