When to split cards in blackjack at 09:27

• Always split 8s or aces. Reasoning: You rid yourself of those bust-friendly 16s or 12s.
• Never split 10s (or face cards). Reasoning: Only an idiot would give up a pretty-sure-thing 20.
• Never split 4s or 5s. Reasoning: You shouldn’t trade in your good chances at 18s or 20s for pairs of crappy 14s or 15s.
• Split any other pair when the dealer has a visible 4, 5, 6, or 7. Reasoning: Never miss a chance to double your bet when the dealer’s likely to bust.
