Hit.Why basic strategy says hit
Hard 8 is a comfortable hitting total. Two hands starting from four are weak, so the pair only splits when the dealer is at their most vulnerable and doubling after the split is allowed.
Engine explanation: Hit with a pair of 4s against 4. Take another card under the selected rules. This is a long-run basic-strategy decision, not a prediction of the next card.

Training rules: six decks · dealer stands on soft 17 · no surrender
This is a separate educational profile. Rules can differ between app tables and other games.
- Six decks. Dealer stands on all 17s, including soft 17.
- US hole card and peek: decisions assume the dealer has checked and does not have blackjack.
- Double any first two cards, including after splitting. Doubling ends the hand after one extra card.
- Split equal card values into at most four hands. Split aces receive one card each; no resplitting aces.
- No surrender. A natural blackjack pays 3:2; 21 after splitting is not a natural.
- Total-dependent strategy. No card counting or expected-value estimates.
