Casino gambling online continues to be as popular as ever and apart from casino slots the most frequently played casino game appears to be blackjack which is quite understandable as it is a very easy game to play and many people will have played a version called pontoon in a social environment. Blackjack gambling can be quite lucrative as you are playing against the dealer and in reality you stand as much chance as the dealer of having a winning hand but the dealers advantage is when you go over 21 or bust as the dealer wins regardless of what happens afterwards which means even if the dealer goes bust you have still lost. To give yourself a better chance of winning when gambling at online blackjack you need to still be in the game when the dealer goes bust and if that happens, you win regardless of what you have in your hand which means even with 12 or 13 you still win when the dealer busts. It is of course impossible to know for sure when the blackjack dealer will bust but when online blackjack gambling at an online casino there is always one of the dealers cards visible and that is your only clue together with the fact that 5 out of the 13 cards in each suit are 9 or above which approximately 38%. This fact gives rise to the opinion that a 5 or a 6 in the dealers hand in blackjack gambling is considered weak as there is a 38% chance that the other card will be 9 or 10 giving a total of 14 to 16 which as the rules of online blackjack make the dealer draw a card gives a reasonable chance that the dealer will bust. So as well as looking at your own cards when online blackjack gambling, keep an eye on the dealers one card as it might give you a clue.
