There is NO evidence that this guy Al was ever a winning poker player. In the following piece, Al admits to being an online Paid Shill... and also claims:
"At the lower limits, say anything under 3-6, it’s often literally impossible to be a long term winner, so onerous is the house‘s cut."
(1) This is the first "proof" I've ever seen that Online Casonos are filling tables up with Paid Shills... so people on 2+2 are covering this up.
Consequently, I would put the probability that MANY poker sites are running House Bots at precisely 100%. That's why they are hiring Bot Experts from universities... who are in no way security experts skilled at stopping external threats.
(2) The stats below (run on 16,000,000 $1-2 and $2-4 NLHE PP hands May-Dec 2008 with a 70,000 hand cutoff)... completely discredits Al's view on low stakes winners. About 1% of regular players at this level make > 100K/year.
