Some people have asked me in the past how casinos manage to create their edge at blackjack when the dealer is forced to draw to 17? Basically it is one of two factors and the first one is absolutely huge. This is to do with the dealer always acting last. This advantage is so huge that it is akin to having position in poker.

If you think about this for a minute then the advantage is rather obvious. Every time that you take a card and bust then the dealer wins. So if you have 13 and they have 10 then you feel compelled to take a card to better your total and this is correct play. But there will be many times where you will recieve a ten value card or a nine value card and bust immediately. But yet when the dealer plays on then the dealer may well turn a card from 2 to 6 and then bust.

But if the dealer busts after the player busts then the hand is not a push but a loss for the player. This advantage is substantial but it is not one to be over estimated. With accurate basic strategy then the house edge is only in the vicinity of 0.5% and with even adequate card counting skills then this can be at least reduced to 0% and possibly a slight edge.

The second and more subtle factor is connected to the first and this is that the player will be forced to bust their own hand in an attempt to improve their total. This is correct play and cannot be avoided and is another reason as to why the house starts with an edge and the 3/2 pay offs for blackjacks/naturals do not do enough to offset this.
