The General said:
Forget the bonus, just beat em' with your money.
Silly and virtually impossible to do longterm without the bonus.
Why?
Even with a LEGIT casino, one is playing a NEGATIVE EXPECTATION game in the longrun.................so luck is the longterm factor whether you win or not.
However, scraping up a bonus of say 25-100% and playing perfect strategy will ulitimately provide you a profit at most casinos you choose to play at.
As mentioned though, these casionos are long and far between these days, but still many out there with nice bonuses that have a good pay history.
As mentioned, BODOG would be one of those fitting this bill.
