Here's a blackjack basic strategy matrix to help you perfect your basic strategy.

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

Playing tight basic strategy reduces the house edge in blackjack to well below 1%.
