2) Try and Beat the Dealer.
Since blackjack is a one on one battle: you versus the dealer, focus on beating the dealer. Instead of trying to get 21, try to guess what hand the dealer will receive and accordingly play your hand. Remember that the dealer at a regular casino or even at an online casino has to stop taking more cards if the cards on the table add up to 17. But if their cards add up to 16 or any number less, they will have to take another card.
3) Look at the dealer's card facing up.
The only way to play is to look at the dealer's card facing up. If it is a low card like a two or anything up to a 6 or 7, try and get a high number combination. If it’s a 9 or 10, the odds are high that he has a 10 underneath or at least he will be forced to take another card. So, reach anything up to 20 or 21, but its better to even stop at a 18 or 19 and hope they will over-run the sum of 21.
