Mickey, Rob never claimed to beat negative video poker. All he's done is win at certain times and then said he quit when ahead.
Now I can't tell you if his reported profits are true and after all Rob has told us that he uses all sorts of deductions to offset his video poker profits. So we'll never know.
However he has presented the math of his special plays as well as the conventional plays for all to see. He has been 100% clear that his special plays are all at a disadvantage to the conventional plays. He has never denied the math. He has only said that less than 5% of the time (and that could mean less than one-tenth of one percent of the time) he has hoped a special play would give him luck.
Do not confuse that with his other hostile words.
Frankly, Rob's system of playing full pay 8/5 Bonus Poker with a conventional strategy 95%+ of the time is easier to believe than claims that someone can earn $500 a day playing must hit by low level slots five days a week because that would mean the slot player is winning 20% more than Singer's $100,000 a year.
