As my experience its better to play in gambling offline or live than playing in online.. because in real life we will see who deal and we can see that the deal of cards there's no fraud.. than we play in online that our enemy is computer.. we cant easily find about the program if the game has no fraud..
many trick can do in card games, how if you've deal with a person have a skill cheat on card games. i guess for both trick in online or offline is same and the only one can beat that's trick is luck.
I also agree with you,playing offline give me more advantage to think weather to to bet or not like in roulette.
Its hard to win at online casino as the games there is build to win.
