The owens isn't so good.
I wouldn't call it stupid though... just... 2nd class stuff.
3.Nc3 is not a challenging line though, and IIRC black should be fine after 3...Bb4 (like you played in the game).
But then something went wrong. Not sure where, but certainly by the 12th move. 12.fxe is pretty unusual for someone rated 1800 to miss. Black's position is pretty miserable after that.
In any case, looks nothing like cheating. Just an idiot with a big ego accusing you.
Look again.
I post seriously to anyone I don't think is an idiot. I posted seriously in your topic because you seem like a normal person.

By the way, this NM defends the owens, he says he plays it in tournaments and all that..
Still not a great opening, but notice I didn't call it stupid.
