Three popular bad strategies encountered at the blackjack table are: never bust, mimic the dealer, and always assume the dealer has a ten in the hole. All three are very bad strategies. Following are my specific comments on each of them, including the house edge under Atlantic City rules (dealer stands on soft 17, split up to 4 hands, double after split, double any two cards) of 0.43%.
Never bust: For my analysis of this strategy I assumed the player would never hit a hard 12 or more. All other decisions were according to correct basic strategy. This "never bust" strategy results in a house edge of 3.91%.
Mimic the dealer: For my analysis of this strategy I assumed the player would always hit 16 or less and stand on17 or more, including a soft 17. The player never doubled or split, since the dealer is not allowed to do so. This "mimic the dealer" strategy results in a house edge of 5.48%.
Assume a ten in the hole: For this strategy I first figured out the optimal basic strategy under this assumption. If the dealer had an ace up, then I reverted to proper basic strategy, because the dealer would have peeked for blackjack, making a 10 impossible. This "assume a ten" strategy results in a house edge of 10.03%.
