left vertical edge and the dealer's up card along
the top (A stands for Ace). The intersecting square is the basic
strategy play for that circumstance.
H =
Hit
S = Stand
D = Double down
P = Split
H/R = Surrender if allowed, otherwise hit
H/P = Split if allowed to double after a split, otherwise hit
NOTE: Your hand less than 8 = always hit

If you do play basic strategy, the
house edge will be reduced to well below 1%.
