How much does it affect your ability to play against a player wearing sunglasses (dark glasses) at a live table. As for me there are many more ways to read a person other that their eyes and such. What other tells do you see at the tables?
If he wears sunglasses then there are other tells , check https://www.cardschat.com/poker-tells.php for info . I personally check his hands'movements whether their speed is changed or not everytime , if they 're still or cannot , the shoulders , also the mouth and neck if he's licking his lips , of course the other charachteristics (his clothing , his speech ,the betting patterns last but not least ) .
The guys with the sunglasses are actually giving off more by wearing them than they think. Its the same guy that wears the hoodie if allowed and they give off the tell that they are used to playing online,translating to being more agressive in certain spots.
When I first played a few online two ornaments I experimented with wearing sunglasses and not wearing them LOL I found I was very uncomfortable wearing them so I just stop doing it. I don't know if it really matters because a lot of times people thought I was bluffing when I wasn't and vice a versa. So I don't know if wearing the glasses would have made any difference or not actually I was fidgeting around in my chair a lot one time and that made them all think I was bluffing LOL but I really wasn't I was just very uncomfortable
I occasionally wear sunglasses when playing live but the only reason is the lighting is so bad in my local casino that I end up with a massive headache at the end of a long session.
Invariably I get at least a few comments from people about it - I just ignore them and think, "Yeah, I need to worry about giving off tells from a bunch of people that play every hand to the river."
Needless to say the motivation behind actions and the actions themselves are often different.
I don't think that sunglasses have the ability to help somebody in poker, cause I don't think that Ivey,Brunson or Negreanu use sunglasses, playing poker so it is not necessarily to be the best.
