Ring games take a different attitude.
Like BillyTheBull said, stack management is different. There are times in tournament where you should shove even though you know you're chances of winning aren't good, simply because otherwise you're left short stacked and thereby nearly powerless. Whereas in ring games you can always rebuy when you're down on chips, so folding those big hands falls into the realm of "loss management" rather than towards increasing your
odds of a bigger payoff down the road. That is, your decisions in ring games are for the most part, about short term/immediate results, not a winners-take-all sort of prize down the road. You don't need to stack *anybody* to be profitable. Nibbling here and there is fine.
I feel the
big advantage to ring games is that you get to pick your opposition. You get to see who is at what table and where you'd be sitting before deciding on a table.
I usually two-table the 6-max games, and put myself on about 5 waiting lists. When a game opens I'll decline it if I don't like the opposition or position.
Even when I'm sitting at two tables I'll still accept the open tables to see if there is a better spot open for me, in which case I either leave one table and join the new one, or play three tables at a time.
Another advantage of ring games is that if your bountiful table starts to sour you take your chips and leave for more fertile ground. I left a game last night because a couple donks left, then a good player sat down to my left. I didn't need him challenging my continuation bets.
