Chess.com is a perfect learning place with endless learning sources. But can one have 1800+ with these sources without a personal coach?
I've been a member of chess.com for about two years and have been playing turn-based for a little over a year. Never had a coach and am now flirting with 1800 (over 1800 very briefly). The Study Plans, as mentioned above, have been a wonderful addition. It sorts out all of the learning features on the site and puts them in a logical sequence for us. With the Study Plans and lots of games, I look forward to going much higher than 1800.
Short answer, a coach is not required, just stay with it and remember to have fun.
Congrats! Very motivating for me.
Even the Great Fischer wasn't rated at 1869 after only nine games
