Well if you have friends which is also knowledgeable on blackjack and want to test what you learn from the video tutorial you learn from what OP provide then this is good since this will never cost some bucks to us if we want to play. But if we don't have then maybe do this slowly by using small amount of money since for sure we can also learn from our experience since mostly our first try will be bad and we lose our money in some instances.
Also after learning the basic we also need to consider to practice our emotion and set proper fund management so that we will not exceed to our balance and came to the point we get broke.
If we have friends who already know how to play BlackJack, it will make it easier for us to learn more because our friends can also teach lessons about BlackJack that may not be in the video. It will help us to know how to play BlackJack better and who knows, we can become a pro players.
Coaching emotions is an important part of learning for a BlackJack player because, in the BlackJack game, we will encounter bluffs made by the opponent so that our emotions can increase. And don't forget to adjust the number of our bets because we can avoid a lot of losses with that setting.
Trying while watching will quickly understand a toturial, so both must be practiced simultaneously, so watching the spectacle alone will be difficult for someone to understand the essence of the review described. I think the video about BlackJack includes a complete explanation but it doesn't matter if we study other tutorial videos.
It can also be done together because we can learn and practice what we get in the video. But in this case, maybe we will need an opponent to play or we can just install the BlackJack game on our cellphones or computers so that we play it offline. We must learn BlackJack lessons from other sources because, with the more we learn, we can improve our ability to play BlackJack.
