Blackjack table

Basic strategy for 2,2 against a dealer 8 is to hit, since splitting 2s is only correct against dealer 2-7 (4-7 without DAS). Chat is off, so the table message is empty.

Hard 13 against a dealer 8 is a standard hit, since the dealer's likely final total of 18 or better beats a standing 13 more often than the risk of busting costs.

Hard 15 against a dealer 8 is a hit under basic strategy, since standing loses more often than hitting. Doubling and splitting are not legal, so hit is the best legal action.

Hard 11 against a dealer ten is a double in a multi-deck game where the dealer stands on soft 17, since basic strategy doubles 11 against every upcard including a ten. Chat is off, so the table message is empty.

Hard 18 against a dealer ten is a standard stand; hitting risks busting and doubling has negative expected value.

Hard 11 against a dealer 9 is a standard double, since it has a strong chance of making 19-21 and the expected value is higher than hitting.

A hard 20 is a very strong hand against a dealer 9, and splitting tens is a worse play in basic strategy. Standing has the highest expected value.

Hard 10 against a dealer 2 is a standard double in basic strategy, since the dealer is likely to bust or end up weak and a 10 draws well to 20.

Hard 20 against a dealer 8 is a very strong hand, and basic strategy says to stand rather than split tens or double.

Soft 17 against a dealer 3 is a standard double in multi-deck blackjack, and doubling is legal on any first two cards.

Pair of 4s against a dealer 4: basic strategy for DAS is to split only vs 5-6 (some charts also 4), and with 6 decks and S17 the standard play is to hit. Hitting 8 is the safer, near-optimal play.

Soft 19 against a dealer 4 is a stand in basic strategy, since the dealer is likely to bust or finish below 19 and hitting risks weakening a strong hand.

Hard 7 against a dealer 3 is too weak to double under basic strategy, so I hit; doubling is only correct with 9 to 11 in this spot.

Hard 17 against a dealer 3 is a stand; hitting risks busting with little chance of improving the hand.

Hard 10 against a dealer 8 is a standard double, since the expected value of doubling beats hitting in a 6-deck game where the dealer stands on soft 17.

Hard 11 against a dealer 4 is a strong doubling spot, since the dealer is likely to bust or finish weak and any ten gives me 21.

Hard 13 against a dealer 2 is a basic strategy stand, since the dealer busts often enough with a 2 upcard and hitting risks busting a stiff hand.

Hard 9 against a dealer 6 is a standard double, since the dealer is likely to bust and a 10-value card gives a strong 19.

Hard 8 against a dealer 6: basic strategy for a multi-deck game says hit. Doubling is only marginal at 8, and basic strategy reserves it for 9-11 (a few sources double 8 vs 5-6 in specific counts), so hitting is the standard play.

Hard 18 against a dealer 6 is a clear stand, since the dealer is likely to bust and hitting risks busting for little gain.

Hard 9 against a dealer 3 is a standard double in a multi-deck game, since the dealer is likely to bust or finish weak and a 10 or face card gives a strong total.
