Model's stated reason

Basic strategy says to stand on hard 12 against a dealer 5, since the dealer is likely to bust and hitting risks busting first.

Model's stated reason

Basic strategy for a hard 14 against a dealer 2 with S17 is to stand, since the dealer's weak upcard gives a real bust chance and hitting risks a bust of my own.

Model's stated reason

Basic strategy says to double a hard 10 against a dealer 3, since the dealer is weak and I am likely to draw a strong total.

Model's stated reason

Hard 11 against a dealer 8 is a standard double in basic strategy. The expected value of doubling is higher than hitting.

Model's stated reason

A hard 20 against a dealer 10 is a clear stand. Only an ace improves it, and any other card busts.

Model's stated reason

Hard 18 against a dealer 10 is a stand in basic strategy. Hitting or doubling risks a bust with little chance of improving.

Model's stated reason

Basic strategy says to hit soft 18 against a dealer 9, since standing on 18 is an underdog against the 9's strong final totals. Hitting a soft hand cannot bust.

Model's stated reason

Hard 18 against a dealer 9: basic strategy is to stand, since hitting risks a bust more than it improves the hand.

Model's stated reason

Hard 18 against a dealer 10 is a stand under basic strategy. Hitting or doubling risks busting on most cards.

Model's stated reason

Hard 20 against a dealer 6 is a strong made hand. Basic strategy says never split tens, so standing has the best expected value.

Model's stated reason

Model's stated reason

Hard 18 against a dealer 10 is a stand in basic strategy. Hitting or doubling risks a bust for very little gain.

Model's stated reason

Model's stated reason
