Do you often watch videos like this to improve your skills in playing BlackJack or other card games?
I do it for anything that interests me, not just blackjack tutorials and videos but as well as other card games too.
Or do you feel so confident in your abilities that you don't need such video courses?
Nope.
I'm not confident with my capability if the game is blackjack. I'm not an expert there but if it's the other games and I know I'm good with it, I don't think there's a need for me to watch any video course.
But it's helpful to the people like me who are not good at it.
