Blackjack table

Soft 13 against a dealer 4 is a profitable double spot in multi-deck basic strategy, so I increase the wager while keeping the option to draw exactly one card.

Hard 8 against a dealer 10 is a hitting hand; doubling would be too aggressive with a weak total against a strong upcard.

Hard 14 against a dealer 10 is a losing stand, so I hit to try to improve to a stronger total.

Hard 12 against a dealer 10 is a losing stand, so hitting is the correct basic-strategy play. Splitting 6s against a 10 is not favorable.

Hard 11 against dealer 4 is a strong double: any 10-value card makes 21, and the dealer's 4 is a bust-prone upcard, so maximizing the bet is +EV.

Hard 13 against a dealer Ace is a losing stand, and doubling is not justified; hit to try to improve toward 17-21.

With hard 15 against a dealer Ace, basic strategy is to hit; the dealer is likely to make a strong hand, so standing is worse.

I have a hard 19 against the dealer's Ace; standing is the clear play since hitting risks busting and the dealer has already peeked for blackjack.

Hard 13 against a dealer 5 is a standing hand under basic strategy; the dealer is likely to bust, so hitting or doubling would only add risk.

Hard 17 against a weak dealer 5 is a clear stand; hitting 17 risks busting and doubling is not justified with a made hand.

With a hard 18 against the dealer's king, standing is the optimal basic-strategy play; splitting 9s or doubling would increase risk without improving expected value.

Hard 16 against an Ace is a losing stand, and since surrender is unavailable, hitting is the best legal play to improve the hand.

Hard 17 against an Ace is a standing hand in 6-deck S17 blackjack, since hitting risks busting and the dealer must stand on soft 17.

Split the 4s against the dealer's 6; with double-after-split allowed, splitting creates two favorable starting hands against a weak dealer upcard.

With a hard 14 against the dealer's 6, standing is correct because the dealer is in a bust-prone position and hitting risks busting before the dealer acts.

Dealer shows a 6, so standing on hard 14 lets the dealer take the bust risk rather than hitting into a likely strong dealer hand.

Hard 15 against a dealer 7 is a losing stand, so hitting gives the best chance to improve without risking an incorrect double.

Hard 7 against a dealer 6 is a favorable double situation, so I will double to maximize expected value.

Hard 14 against a dealer 10 is a losing stand, so hitting gives the best chance to improve without risking an additional double.

I have a hard 20, which is a strong standing hand; hitting risks busting and the dealer must beat 20 to win.

Hard 12 against a dealer 2 is a hitting situation in basic strategy; the dealer's 2 is not weak enough to justify standing on 12, and doubling on 12 is not sound.

With a hard 12 against the dealer's 9, standing is likely to lose and doubling would risk more on a weak total. Hitting gives the best chance to improve without increasing the wager.

Hard 13 against the dealer's queen is a losing stand, so I hit to improve toward 17-21.

Hard 12 against a dealer 8 is a hitting hand because standing leaves too many dealer-made totals ahead; doubling is not justified with a weak 12.

Soft 18 against a dealer king is not strong enough to stand, since the dealer likely has 20; hitting cannot bust and gives a chance to improve to 19-21.

Hard 16 against a dealer 10 is a losing stand, so I hit to try to improve; dealer blackjack has already been ruled out by the peek.

Hard 10 against a dealer 3 is a strong doubling opportunity, with good chances to make 18-21 while the dealer is vulnerable.

Hard 14 against a dealer 9 is a losing stand, so I hit to try to improve without risking an extra double bet on a weak total.

I have a hard 20, which is a strong standing hand. Against the dealer's 9, hitting risks busting and cannot improve enough to justify the risk.
