Blackjack table

Always split aces; against a dealer 8 (stands on all 17s, peeks), splitting A,A is clearly better than playing a soft 12.

Hard 17 against a dealer Ace (dealer stands on soft 17, no insurance, dealer has peeked and has no blackjack) is a stand under basic strategy; hitting risks busting too often.

Soft 16 (A,5) against a dealer 6 is a standard double in basic strategy for S17 multi-deck games, since the dealer busts often and the extra bet is favorable.

Hard 20 against a dealer ten is a strong hand, and standing beats splitting tens or doubling in basic strategy. Chat is off, so the table message is empty.

Hard 13 against a dealer 7 is a hit by basic strategy, since the dealer is likely to make a 17 or better and standing loses more often. Doubling is not favorable with 13.

Hard 15 against a dealer 7 is a hit under basic strategy: the dealer's likely final total is 17, and standing on 15 loses more often than hitting does.

Hard 17 against a dealer Jack: basic strategy says stand, since hitting risks busting too often and doubling is clearly unfavorable.

A hard 20 is a very strong hand against a dealer 7; splitting tens or doubling is worse than standing, and chat is off so the message is empty.

Hard 6 against a dealer King is a clear hit by basic strategy; doubling is not favorable against a 10 and standing on 6 is far too weak.

Hard 11 against a dealer King is too weak to stand on, and doubling is not legal with three cards, so hitting is the best legal play.

Hard 20 against a dealer 10 is a very strong hand, so standing is clearly correct; hitting would almost certainly make it worse.

Hard 17 against a dealer 3 is a standard stand; hitting risks busting and doubling has negative expected value.

A hard 20 is a very strong hand against a dealer 3; standing is the basic strategy play, and splitting tens is worse in expectation.

Hard 12 against a dealer ten is a basic strategy hit. Standing only wins when the dealer busts, and doubling is not recommended.

Hard 9 vs dealer 2 is a close call: basic strategy doubles in multi-deck games, but the dealer stands on soft 17, which makes doubling slightly favorable. Multi-deck basic strategy for 9 vs 2 is to hit, while doubling starts at 9 vs 3-6, so I hit.

Hard 12 against a dealer 2 is a hit in basic strategy, and the multi-deck shoe does not change that. Doubling is not legal with three cards, so hit is the best option.

Hard 15 against a dealer 7 is a basic strategy hit, since the dealer is likely to make 17 and standing is only correct against a 6 or lower. Doubling on 15 is not favorable.

Soft 13 against a dealer 2 is a hit under basic strategy, since doubling is only recommended against 5-6 (and 4-6 for soft 15-16). Hitting cannot bust this hand and improves it.

Soft 15 against a dealer 2 is too weak to stand on, and doubling is not legal with three cards. Hitting is safe because a soft hand cannot bust on one card.

Soft 17 (A,2,2,2) against a dealer 2 is a hit in basic strategy since it can't bust and improves the hand on most draws; doubling isn't allowed with four cards.

Hard 17 (A+2+2+2+K = 17) against a dealer 2 should stand; hitting risks busting with little gain.

Pair of 8s against a dealer 9 is a basic-strategy split, since a hard 16 is a weak hand and splitting turns it into two hands that start from 8. Double after split is allowed, which makes splitting slightly better.

Hard 11 against a dealer 9 is a standard double, and doubling after split is allowed, so the extra bet has positive expected value.

Hard 13 against a dealer 9 is a losing stand, and doubling is worse than hitting here. Basic strategy says hit.

Soft 17 against a dealer 7 is a standard double in a stands-on-soft-17 game (6 decks). It has higher expected value than hitting or standing.

Hard 13 against a dealer 7 is a hit by basic strategy. Standing is only correct against a dealer 2-6, and doubling is not favorable here.

Hard 19 against a dealer 7 is a clear stand; hitting risks busting and gains little.
