A front loading dealer exposes the next card to be dealt. This will only occur in a pitch game. There are a few obvious ways that this weakness can be exploited. If you are going to receive a ten or an ace, you should bet large. You can wager probably 5% to 10% of your bankroll on a ten and up to 40% of your bankroll on an ace. Of course if you do wager 40% of your bankroll and receive an ace, you should probably refrain from taking any soft doubles! See James Grosjean's article 42.08% http://www.blackjackforumonline.com/content/ACEbjfo1.pdf for a complete discussion on the subject. Also if the next card is a ten, aside from making a big wager you can also bet on the lucky ladies or kings bounty side bet as you have a nice edge there.
Having knowledge of the next card to be dealt can also help with your hit / stand decisions. In many locations the dealer does not take a hole card until the player's hand is resolved, so you can choose to give this card to the dealer if it will make him a stiff. Or if you have 16 and the next card is a 5, you could double down, although such an unusual play might attract some attention and / or get you kicked out.
If your first card is not going to be a ten or an ace, make sure to make a minimum wager, even if you are in a high count.
