I often watch poker videos on YouTube where the player have very good acting to hiding his cards through his flat face. I have seen them being able to win with very bad cards on their hand with a good bluff, all in his chips. So I imagine, and often play poker online, I am very happy if I get a good card and I can't hide it well so just go all in all my chips. So what do you think?, how do other players know when I have good cards when playing online?, Is by check and don't call the bet they know we don't have a good card?, I'm not good at hiding it, sometime when I have double AS, I always all in at the beginning.
there are no better way to play in offline when we are playing against Human(i call human because in online We don't really sure whom we are playing against lol)
In offline ? we are dealing face to face , act to act and teeth to teeth

seeing the reaction of each opponent can give us chance in finding what is the position cards of our opponents , same us if the opponent is good they can also find yours ,
so indeed its Offline gambling is what I wanted to choose playing.
