First Character

• H - Hit
• S - Stand
• P - Split
• L - Concede (Surrender) if already doubled, if not - Surrender, if Surrender not possible - Hit
• D - Double, otherwise Hit
• C - Concede (Surrender) if already doubled, otherwise Hit
• E - Redouble, otherwise Hit

Second Character

• 3 - Hit if 3 or more cards
• 4 - Hit if 4 or more cards
• 5 - Hit if 5 or more cards
• 6 - Hit if 6 or more cards

Third Character

• # - Hit if 6-7-8 possible
• $ - Hit if suited 6-7-8 or 7-7-7 possible
• % - Hit if spaded 6-7-8 possible

Example 2: "D 3" means "Double, except if you have 3 or more cards - in which case Hit"
