I'm surprised nobody's mentioned this, but I'll point out that Bob Dancer's last two columns (April 12th and 19th) at LVA have addressed two of the favorite topics of a couple of this forum's most prolific posters.
"Knowing When to Quit" and "Quitting When I'm Ahead" take dead aim at Rob and Alan's opining on the subjects.
I'm no big fan of Dancer's. I think he should do a disclaimer in each column saying something like, "My rebates, tier statuses, and cashback make my profiting much more likely than 99.999% of all video poker players. If you do what I do without those, you probably won't win." I'm just pointing out that his columns are in complete and utter disagreement with some people's cherished ideas.
One should read what Dancer says, what Rob and Alan say, and make up one's mind as to who is on more solid ground.
