How to read it
Find your hand on the left (hard totals count no ace as 11; soft totals contain an ace counted as 11; pairs are two cards of one rank), then the dealer’s upcard along the top. D means double if allowed, otherwise hit; Ds means double if allowed, otherwise stand; the ≈ mark flags cells where the top two plays are nearly identical — 16 vs 10 being the famous one.
