Blackjack terminology may sound like a foreign language to a complete beginner, but the good thing is, all you need is a little patience and practice to get used to what the different terms mean. For example, your first decision in any game of blackjack should be whether to hit or stand — either ask for another card or refuse additional cards. You could also split pairs, double down or surrender, in which case you'll receive half your bet back. You might even have the chance to take insurance.
