Re: el novicio
Most if not all pros stick to 8 deck games with good rules and good conditions. Attacking the games you describe requires a huge bankroll and an unbelievable act to have any chance at all.
This is entirely untrue. DD games can be very profitable and tend to require smaller bankrolls than do 8D games. This is a function of the greater EV for most DD games compared to 8D games.
While a good act is desirable for 2D games, it is nearly as desirable for games with more decks. I would actually avoid 8D games altogether unless you are able to bankcount or have a spotter.
When you do find a seemingly good 2D game (as posted earlier, CBJN is an excellent resource), make sure that it pays 3:2 for a natural.
I hope that helps.
