The traditional method of learning the Basic Strategy: all decisions in a table. The dealer up card is listed across (horizontally), while the player's first two cards are listed vertically in the leftmost column. For example, dealer's up card is 5. Player's first two cards: A+4; the right move: D (Double Down). The spreadsheet-like table makes it somehow more difficult to learn the best decisions.

H = Hit; S = Stand; D = Double down; P = split Pairs

. Always stand on 17 or greater.
. Always split A+A and 8+8.
. Never split 10+10 and 5+5 (unless you seeing Ion Saliu playing that way).
