1) If the dealer's down card is 5,6,7,8,or 9, dealer has a good hand if 5,6, or 7, and about the same chances as you to draw 1 w/o breaking with the 8 or 9. Figure with A,2,3, or 4 in the hole that the dealer will stand more than you. The worst cards in the hole are the 3 ranks of 10-value cards not seen. Even then, 3,4,5,6,7 drawn will give dealer a standing hand, and all of them are still in the deck except the one 4 on the table as the up card.
