Blackjack table

Basic strategy splits a pair of 7s against a dealer 2, since each 7 starts a stronger hand than standing on hard 14.

Hard 13 versus a dealer 2 is a basic-strategy stand: the dealer is weak enough that hitting risks busting more than it helps.

Hard 17 against a dealer 2 is a clear stand; hitting or doubling risks busting a made hand the dealer is unlikely to beat.

A pair of jacks totals 20, which is already a strong made hand against a dealer ace. Standing is clearly better than hitting, doubling, or splitting tens.

Hard 15 versus a dealer ten is a hit in basic strategy; standing loses too often and doubling is not justified.

Hard 20 against a dealer Jack is a strong made hand; hitting risks busting and standing is the clear basic-strategy play.

Hard 19 against a dealer King is a clear stand; hitting or doubling risks busting a strong hand.

A pair of jacks totals 20 against a dealer 4, which is a strong made hand. Standing is correct; splitting tens or taking another card would only worsen the expected value.

Hard 10 versus a dealer 5 is a standard double: the dealer is weak and the extra bet has positive expectation.

Hard 20 against a dealer 8 is a strong made hand; standing is the clear basic-strategy play, while hitting, doubling, or splitting would only risk a near-certain win.

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

Hard 20 against a dealer 8 is a clear stand; hitting risks busting a nearly certain winning hand.

Soft 18 versus a dealer 6 is a basic-strategy double when doubling is allowed, since the dealer is weak and the extra bet has positive expectation.

Hard 10 versus a dealer 6 is a standard double: the dealer is weak and the extra bet has positive expectation.

Hard 19 against a dealer ace is a clear stand; hitting risks busting and is far worse than standing.

Hard 15 versus a dealer 7 is a hit under basic strategy; standing loses too often to a made dealer hand, and doubling is not justified.
