Blackjack table

Hard 16 against a dealer ten is a weak spot, and basic strategy says to hit since standing loses more often in the long run. With no surrender available, hitting is the best option.

Hard 19 against a dealer 3 is a clear stand under basic strategy; hitting or doubling would risk busting a strong made hand.

Hard 11 against a dealer 3 is a standard double, since the dealer is likely to bust or finish weak and a 10-value card gives me 21.

Hard 13 against a dealer 5 is a standard stand, since the dealer is likely to bust; doubling is not recommended with a hard 13.

Hard 17 against a dealer 3 is a stand under basic strategy; hitting risks busting and doubling is not favorable.

Soft 16 (A,5) against a dealer King, who has already peeked and has no blackjack, is best played by hitting. Basic strategy says to hit here rather than double, since doubling soft 16 is only correct against dealer 4-6.

Hard 16 against a dealer Kd is a losing spot either way, but basic strategy for a multi-deck game says to hit. Surrender isn't available, so hitting loses slightly less than standing.

Hard 14 against a dealer 10 is a basic strategy hit. Standing loses too often against a dealer ten, and doubling is clearly worse.

Hard 17 against a dealer 9 is a stand in basic strategy, since hitting risks busting too often for too little gain.

Basic strategy for hard 12 against a dealer 4 is to stand, since the dealer busts often with a 4 upcard and hitting risks busting a stiff hand.

Basic strategy for soft 17 against a dealer 2 in a 6-deck game is to hit, though doubling is marginally close under S17 rules. Doubling soft 17 vs 2 is not recommended in most charts (it's double vs 3-6), so hit.

Hard 13 (A+6+6, with the ace counted as 1) against a dealer 2 is a stand in basic strategy, since the dealer busts often with a weak upcard.

Soft 20 against a dealer ten is a strong hand, and standing is the basic strategy play. Hitting or doubling would add risk for very little gain.

Hard 12 against a dealer 6 is a basic strategy stand, since the dealer busts often and hitting risks busting first.

Hard 18 against a dealer Ace (dealer peeked, so no blackjack) is best played by standing; hitting risks busting for little gain, and doubling is clearly worse. Chat is off, so the message is empty.

Hard 15 against a dealer 3 is a stand under basic strategy, since the dealer busts often enough with a weak upcard and hitting risks busting too much.

Hard 14 against a dealer ten is a losing spot either way, but basic strategy says hit because standing loses more often than the risk of busting.

Hard 17 against a dealer ten should stand, since hitting has a high bust chance and little chance to improve.

Soft 18 against a dealer 3 is a basic strategy double in multi-deck games (dealer stands on soft 17), because it beats standing in expectation.

Hard 17 against a dealer 7 is a stand in basic strategy; hitting risks busting too often and doubling is clearly wrong.
