wow..in 5 hands you lost $100 at .5/$1?!!! I've played a LOT of hands of .5/$1, and have rarely seen pots over $20, much less a pot where one player put in $20....seems like kind of an "outlandish" claim to me....

To your question though, how much of an edge do you need? A small edge, over thousands of hands, can equal big results. As a former handicapper, you should realize that it only takes a small edge repeated enough to equal a HUGE profit.
