Not the main reason to play online. If you're that expressive, you probably play too emotionally anyway. Online is a great way to see lots of hands and get used to automatic responses to certain situations so you have fewer live tells anyway.
Do you play online because in real life you have tells that would give away your hand?
I play online because I can multi table, so I can " profit " more with that... And are just the tells that make me find the game fascinating.
But now talking about online poker, if you haven't noticed when someone takes too long to 3bet you, especially if you know that the player has some experience, you might consider that he is thiking how he can bluff you...
Usually beetween 30-50 Big blinds good regulars will eat you down in tables.
Other tell is how fast is someone calling you, if vilain instant call you, you can consider that he doesn't even think about a re-raise on the hand, and his hand is not that strong.
Here's what I have with my experience with tells, of course you can't take what I've said as a absolute true but write it down the tells I've said in a paper and test your on.
I play online because i can profit more with that, when i have time i go to live sure but it s different because online you can play more hands per hour than at live. I like to play live for socialization and competition
We don't have a casino so I play online. The role of tells in live poker is greatly exaggerated in my opinion. It is not enough to notice the body movements of the opponents, but it is necessary to interpret them correctly.
