No offence but 1800 is really low if it's your lifelong passion. I don't even like chess and I got that in 6 months.

An insightful quote there: Being good at chess is not the only ultimate goal. Perseverance is the ultimate goal. People who never become good but have played chess for 50 years are a lot successful than GMs who would quit chess after one awful tournament.
Chien took the time to help me understand where I went wrong in our 45|45 game today. He is really passionate about the game and helping others to understand it. Very good coach and tournament director!
