Okay, how about this "Extra Simple Strategy." Follow the first rule that applies.
Split eights and aces.
Double 10 and 11.
Hit hard 9 or less.
Hit hard 12 to 16 against a 7 to ace.
Hit soft 17 or less.
Otherwise, stand.
That is just 30 words, counting the numbers as words. The cost due in errors relative to the full basic strategy is 0.44%. That is a lot more than the 0.14% of my full Simple Strategy, but is still about half the cost of errors made by the average blackjack player.
This question was raised and discussed in the forum of my companion site Wizard of Vegas.
