Blackjack table

Hard 16 against a dealer 6 is a standard stand, since the dealer is likely to bust and hitting risks busting first.

Splitting 7s against a dealer 2 is the basic-strategy play with double after split allowed, and it turns a weak 14 into two starting hands.

Hard 17 against a dealer 2 is a stand under basic strategy, since the dealer's weak upcard gives a good chance of busting.

Soft 18 against a dealer 2 with the dealer standing on soft 17 is a basic-strategy double when allowed, and doubling after split is permitted here. Doubling captures extra value from a hand that is favored against a weak upcard.

Holding 20 (two kings) against a dealer 8 is a strong standing hand, and splitting or doubling would only add risk.

Hard 13 against a dealer ace is a losing stand, and doubling with 13 is too risky, so hitting is the basic-strategy play here.

Hard 13 against a dealer King is a losing stand, since the dealer likely makes 17 or better. Basic strategy says hit here, and doubling isn't favored with 13.

Hard 12 against a dealer 3 is a stand under basic strategy, since the dealer is likely to bust and hitting risks busting myself.

Hard 16 against a dealer king is a losing spot, but doubling is not favorable here and standing busts too often, so basic strategy calls for a hit.

A hard 10 against a dealer 10 is a weak double spot, so basic strategy favors hitting to improve the hand without committing extra chips.

Hard 18 against a dealer queen is a stand, since the dealer likely makes 20 and hitting risks busting on a 6-card draw of 4 or more. Chat is off, so no table message.

Hard 20 is a strong total that beats most dealer outcomes, and a dealer queen upcard makes busting likely, so standing is clearly best.

Hard 5 against a dealer 5 is far too weak to stand or double, so taking a card is the clear play with no bust risk on one draw.

Hard 12 against a dealer 5 is a standard hit since the dealer's bust chance is high but not enough to justify standing on 12, and the hand has no bust risk from a single card beyond 10 points of exposure that I can accept. Hitting also avoids the weakness of standing on a stiff total.

A hard 19 is a strong total against the dealer's 5, which busts often, so standing avoids the risk of busting on a hit.

Hard 13 against a dealer 5 is a stand under basic strategy, since the dealer is likely to bust. Doubling here is too aggressive with only 13 total.

Hard 15 against a dealer ace is a losing stand, and doubling is not favorable here, so hitting is the best option under basic strategy.

My hard 16 is a weak total, and a dealer Ace threatens a strong made hand, so basic strategy favors hitting against an Ace.

Hard 12 against a dealer 6 is a basic-strategy stand, since the dealer is likely to bust and hitting risks busting myself. Doubling is not favorable with only 12.

Hard 6 against a dealer ace is a weak hand, but doubling on any two cards is allowed and a double here is a reasonable way to press the small edge from the 6 when the dealer's ace is likely to be strong. Doubling commits 10 more chips while the hand has a real chance to improve on one card.

A hard 9 against a dealer 10 is a strong doubling spot, since the dealer's 10 is weak and a single card can bring the hand to 19 or 20 with a good chance of winning.
