@Yalturkmani
It's not clear if he's talking about biggest CHESS achievement or just biggest achievement. If it's chess achievements then it's definitely not off topic.

@youngmoney2299

A master such as yourself should not denigrate the achievements of other people. You're being an ass.

Moving right along ... if the OP meant biggest NON-CHESS achievement in your life then I would say getting my first book (computer science) published.

I have won a state level chess tournament

Gaining 100 rating points in one week and losing 200 the next week. That's a pretty impressive achievement of mine.

@Eleuthero I was merely making a joke and meant no harm from it. I apologize for offending you
