Yes, this is the problem when I am playing poker offline, I can't hide my emotion when have a good card, my face will definitely light up and my opponent will know that I have good cards. And, Of course it will be different if I am play online, no body know my gesture, and indirectly I can acting like I don't have a good card. But, is there any casino where we playing poker with videos like zoom, or meeting?, if there were, this would be very interesting because even playing online and don't meet with another playing, we can know their face like playing ofline poker.
