Blackjack table

Hard 11 against a dealer 4 is a strong doubling spot, so doubling maximizes expected value.

Soft 14 (A,3) against a dealer 3: basic strategy says double only against 5-6, so hit against 3. Doubling is less favorable here, and standing on 14 is too weak.

Hard 14 (A+3+T with the ace counted as 1) against a dealer 3 is a stand by basic strategy, since the dealer busts often with a weak upcard. Chat is off, so the message is empty.

Hard 16 against a dealer 5 is a standard stand, since the dealer busts often with a weak upcard and hitting risks busting too often.

Hard 9 against a dealer 8 is normally a hit in basic strategy, since doubling is only preferred against a 3 through 6 and this is marginal. Chat is off, so the table message is empty.

Hard 13 against a dealer 8 is a hit by basic strategy, since the dealer is likely to make 18 or better and standing on 13 loses more often.

Hard 15 against a dealer 8 is a hit by basic strategy. The dealer stands on all 17s and is likely to make a hand of 17 or better, and standing on 15 loses more often than hitting.

Hard 13 against a dealer 4 is a stand by basic strategy, since the dealer is likely to bust and doubling 13 is not favorable.

Hard 13 against a dealer 5 is a standard stand, since the dealer busts often with a weak upcard. Doubling on hard 13 is not recommended.

Hard 10 against a dealer Ace (dealer stands on soft 17, 6 decks, peek already shows no blackjack) is a hit under basic strategy, since doubling is slightly worse against an Ace.

Hard 19 against a dealer Ace is a clear stand, since hitting risks busting for little gain. The dealer also peeked, so there is no dealer blackjack to worry about.

Hard 20 against a dealer 6 is a strong standing hand; splitting tens is not favorable in basic strategy, and chat is off so the message is empty.

Hard 15 against a dealer 5 is a standard stand, since the dealer busts often with a weak upcard and doubling or hitting is worse.

Hard 19 against a dealer Ace is a clear stand; hitting risks busting and doubling has negative value. The dealer has already peeked, so there is no blackjack.

Pair of 4s vs dealer 2: basic strategy says hit. Splitting 4s is only marginal with double after split, and doubling on 8 is not favored against a 2, so hitting is the standard play.

Hard 17 against a dealer 2 is a stand by basic strategy, since hitting risks busting with a large share of the remaining cards. Chat is off, so the table message is empty.

Soft 17 against a dealer 4 is a standard double in basic strategy (S17, 6 decks), since the dealer is likely to bust or end up weak.

Basic strategy for a pair of 7s against a dealer 7 is to split, and double after split is allowed. Splitting turns a weak hard 14 into two hands starting at 7.

Hard 9 against a dealer 7: basic strategy says double for a 3-6 range, but 9 vs 7 is hit only in some cases; with 6 decks and double after split allowed, hard 9 vs 7 is a hit under standard basic strategy (double only vs 3-6).

Hard 19 against a dealer 7 is a clear stand; hitting risks busting with little upside.

Soft 18 versus a dealer 7 stands or doubles by basic strategy, and here doubling is legal since double after split is allowed. Basic strategy for soft 18 vs 7 is stand, not double; doubling is only correct vs 3-6. So stand.

Hard 12 against a dealer 3 is a basic strategy hit in a multi-deck game where the dealer stands on soft 17. Standing is only correct against a 4 through 6.

Hard 10 against a dealer 2 is a standard double under these rules, since the dealer is weak and a ten-value card gives a strong 20.

Hard 18 against a dealer 5 is a clear stand under basic strategy, since the dealer is likely to bust and doubling or hitting would be worse.

Hard 16 against a dealer 6 is a basic strategy stand, since the dealer busts often with a 6 showing and doubling or hitting is worse.

Hard 17 against a dealer 10 is a stand in basic strategy; hitting risks busting too often and doubling is clearly worse.
