Splitting is where blackjack beginners freeze. You're dealt a pair, the dealer's waiting, and the choice is "two hands or one?" with money on both. Good news: two of the calls are automatic, two are never, and the rest follow the same pattern as the whole game - split into the dealer's weakness. Here are the rules worth memorizing.
These two never change, regardless of the dealer's upcard. Aces and 8s, every time.
Every other pair follows the game's core logic - get aggressive when the dealer is likely to bust (showing 2 through 6), play it safe when they're strong. The shorthand:
To be honest, splits are the decisions most likely to desert you under pressure, because a few of them feel wrong (standing on 9s versus a 7, not splitting that tempting pair of 10s). Reading the list once won't stick. The strategy drill deals you random pairs and grades every call against perfect play, and the full strategy chart shows every split in one grid. A few minutes of reps and the pattern - always Aces and 8s, never 10s and 5s, the rest into a weak dealer - becomes second nature.
Random pairs, instant feedback, graded against perfect basic strategy.
Aces and 8s, no matter the dealer's upcard. Aces give two hands starting at 11; splitting 8s escapes a 16, the worst hand in the game.
10s (you already have 20) and 5s (you have 10 — double or hit instead).
Against a dealer 2-9, but stand against 7, 10, or Ace. Your 18 already beats the dealer's likely 17 on a 7.
Because 16 is the worst hand in blackjack. Splitting ditches the 16 and starts two hands at 8 — an escape, not a power play.
