2 questions: Faith worth it? Great Christian poker player?

I don't frequent this forum, so I apologize if these questions have been covered. If so, any links? I couldn't find any.

#1:
This is average Joe. Joe isn't of intellectual superiority, so Joe cannot deduct that God doesn't exists, assuming an unbias rational mind could deduce this. Also Joe hasn't had a spiritual experience 'proving' God exists & Jesus is who Christians believe He is.

Joe is undecided. Is faith worth it? If the criteria for Joe to get into Heaven is to believe in Jesus and that He died for Joe's sins, then is it worthwhile for Joe to believe in Him. Why or why not?

#2:
I'm not sure how to define a great poker player, but let's say someone who can beat the Big Game where Chip, Doyle, Ivey, Greenstein, and Giang play in. Can a Christian become a great poker player. I thought I read somewhere that Sklansky said this was highly unlikely or maybe it was flat-out no. If no, why not?

Edit: I'm more interested in #1 than #2 if that matters to anyone else.
