what are five or six deceptions in the play. How would you rate the seriousness of the deceptions?

When Troy makes up a story about encountering the devil, Rose stops him midstream with two simple words, "Troy lying."

in Act Two, scene one, Troy admits his affair with Alberta to Rose, excusing his behavior by expressing to Rose that spending time with Alberta allowed him to provide an illusion of accomplishment and escape from responsibility. Troy says, "Then when I saw that gal…I got to thinking that if I tried…I just might be able to steal second." Troy perceives his relationship with Alberta as a laudable move in a baseball game, as a personal accomplishment. Rose sees Troy's lies and deception about the affair as simple and straightforward self-absorbed betrayal. She says, "We're not talking about baseball! We're talking about you going off to lay in bed with another woman…[w]e ain't talking about no baseball."

Rose's accepts Troy's illegitimate daughter, Raynell as her own. I believe that in its own way this is a form of self deception.
