re: Poker & Stealing in Cash Games
I'd have to agree that you'll find a lot more players who are willing to throw in the extra quarter or 2 so the steal may or may not work as much, but you should definitely make your attempts, particularly if the players left of you are able to fold.
It may take a nice follow-up bet on the flop, but it should be done especially if the board isn't connected. Players should catch-on eventually, especially if you're playing for a lengthy amount of time on one table. Then you'll be able to prey on a player(s) if when you do hit when holding a legitimate hand. It will keep the rest of the table guessing.
