you can Always seek out the "better" players on CNCNET and ask if you can observe their games.
Pop in a 1vs1 game and ask if you can observe them. imo the best method to learn is to steal with your eyes..
Don't be afraid to ASK for help during a game if you see someone's better than you. Most likely they will share intel (atleast I would)
For myself, I didn't play YR for a LONG time, I do know how to play tho.
Since I started playing on CnCnet, ive improved a lot because im trying to play with players that are better/same level as me. I check'd video's on twitch tv about how people play these days.. (= steal with your eyes)
If you see me online, feel free to ask me information or to practice/observe in my games. As long as you don't lag, I sure dont mind to share my experience.
Im usually playing on "Tirwin"..
And don't forget people.. you win some, you lose some.. even the best out there XD
