Action timeline

Model's stated reason

Hard 10 versus a dealer 2 is a double in basic strategy; splitting fives is never correct.

Model's stated reason

Hard 20 versus a dealer 10 is a clear stand; hitting or doubling risks a bust, and splitting tens is a negative-EV deviation.

Model's stated reason

Hard 16 versus a dealer 10 is a hit under basic strategy; doubling would only increase exposure on a weak total.

Model's stated reason

Hard 16 against a dealer 4 is a basic-strategy stand: the dealer is weak and likely to bust, while hitting risks busting a made hand. Doubling is not justified with this total.

Model's stated reason

Soft 14 versus a dealer 10 is a hit in basic strategy; doubling is not justified against such a strong upcard.

Model's stated reason

Soft 19 against a dealer 10 is a strong total; standing is the correct basic-strategy play since hitting risks busting a made hand.

Model's stated reason

Soft 16 versus an Ace is a weak total that should be hit under basic strategy; doubling is only correct against weaker dealer upcards, and standing leaves too many losing outcomes.

Model's stated reason

Hard 16 against a dealer ace is a hit under basic strategy; standing loses too often when the dealer makes a hand.

Model's stated reason

Hard 15 versus an Ace is a hit under basic strategy; standing loses too often to the dealer's strong upcard and doubling is not warranted.

Model's stated reason

Hard 9 versus a dealer 7 is a hit in basic strategy; doubling is only favored against 3–6, and standing leaves too weak a total.

Model's stated reason

Hard 19 against a dealer 7 is a clear stand; hitting risks busting a strong made hand.

Model's stated reason

Hard 18 versus a dealer 10 is a stand in basic strategy. Splitting nines against a ten is a negative-EV play, and hitting or doubling risks busting a made hand.

Model's stated reason

Hard 18 against a dealer 10 is a clear stand; hitting or doubling risks busting a strong total.

Model's stated reason

Hard 16 versus a dealer 8 is a hit in basic strategy; standing loses too often and doubling is a poor risk.

Model's stated reason

Hard 18 versus a dealer 10 is a clear stand; hitting or doubling risks busting a strong total.

Model's stated reason

Hard 19 against a dealer 5 is a strong made hand; standing is the clear basic-strategy play, while hitting or doubling risks busting a near-certain winner.

Model's stated reason

Hard 18 against a dealer 5 is a strong total; standing is the basic-strategy play, while hitting risks busting and doubling is unnecessary.

Model's stated reason

Soft 14 versus a dealer 7 is a hit in basic strategy; doubling is only correct against 5 or 6, and standing leaves too many dealer outs.

Model's stated reason

Soft 16 against a dealer 7 is a hit in basic strategy; standing leaves a weak total that loses to most dealer outcomes.

Model's stated reason

Hard 16 against a dealer 7 is a hit under basic strategy; standing loses too often when the dealer makes a hand.

Model's stated reason

Hard 17 against a dealer 7 should stand; hitting busts on any card 5 or higher and the expected value of standing is better.

Model's stated reason

Hard 15 versus a dealer 9 is a hit under basic strategy; standing loses too often to a made dealer hand, and doubling is not justified on this total.

Model's stated reason

Hard 7 against a dealer 9 is a clear hit; standing or doubling would be far worse.

Model's stated reason

Hard 17 against a dealer 9 is a clear stand; hitting risks busting a made hand.
