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.
