Game example would be useful, wait...
Like in your ongoing game against messicano82?
Roughly, you can consult databases, opening books in Daily chess (not in Live chess), yet consulting game in any other way is considered cheating, past move of not. I will refer this post to mods, with accusation of cheating regardless your ignorance, mostly with hope that you will gather enough composure, or be learned a such. Capeesh?
