That guy needs to be careful what he says. I like to talk at the table... alot. It's part of my game, and I spose I have to work on it like everything else. But I try to be friendly to most, and shittalk some into steaming off chips.
What this guy is doing is pulling his pants down and showing his pimple covered ass. Take his money as often as you can, he will give it to you frequently I bet.
The Ring vs Tourney talk is quite interesting to me. I often feel backwards in the poker community as a ring player first and a tourney player second (or maybe way lower than second).
The obvious big difference is cash games don't have the artificial gamble inducements that tourneys have. In a tourney you have strategy based on skill of the field, structure of the game, and finite chipstack.
I see tourney players coming into ring games getting hammered all the time for trying to gamble like a tourney. I LOVE tables with these players.
As to which takes more skill... It's like riding the Tour de France
vs. a Velodrome track race. Cash game is purer I think. More subtle and grindier, yes. Tourneys have more strategic depth.
