Was I the only one waiting in vain for the final sting?

Rating: 7/10 (8 August 2017)

I agree with many things written here about direction, acting, pool shooting etc. What I don't get here is the plot.
The movie seems two consist of two parts which don't really connect, though you'd expect them to.
Fast Eddie took young Vince with him in order to teach him the tactics of losing and winning, with the final goal of betting on him against low odds and making big bucks for everyone.
After a series of hustling scenes, some involving Vince's girlfriend Carmen, Eddie falls for one himself. He becomes over-emotional about it in a way that totally doesn't fit his character so far. Then, against any sense, his frustration leads him to give up on Vince. He yells at Carmen and him to continue to Atlantic City on their own, as he can't teach Vince anything anymore.
At this point of the movie I was SURE that this dramatic move was a part of some big plan that Eddie had, and actually wondered how come Carmen and Vince bought it so easily. But as it turned out... there was no big plan. When they met in Atlantic City I was excepting something really interesting to happen and nothing did.
As the movie ended when Eddie and Vince matching, Eddie saying "I'm back!", I thought that perhaps the whole journey was a scam hiding the fact that Eddie was still in good shape. I came here assuming that the FAQ would answer my questions. But nothing? This is just it? Eddie financed the journey just to use Vince's talent for a short while and small money? And then Eddie decided to return playing? Is that all? Disappointed.
