I play mostly ring games with the occasional tourney and sng. I would definitely consider myself a much better cash game player then tourney player.
For me cash games are more about limiting losses and waiting for that time when you have an all in push in front of you with the nuts. It will happen if you are at the table long enough. It's about stacking someone here and there, and limiting losses. It's not as difficult for me to know when to lay a monster down in a ring game then it is in a tourney for some reason.
I like the fact that I can play 3 to 4 tables in ring games with a TAG approach, not worrying about having to lay down a big hand because time, blinds going up, etc aren't a factor. I can wait for my hands without being stressed about making a move. In other words if you flop your set and you are almost sure someones drawing to their flush and you see that hit on the river, you can just lay it down knowing that you can get it back. You have all day to pick a better spot.
I definitely rely more on implied odds
in ring games which may not be the correct philosophy but works out well for me.
I feel to much pressure to make a move in a tourney, and don't feel that in ring games.
