The following replicates composition dependent basic hit/stand strategy when dealer's up card is 10 for 8 or fewer decks if followed in its entirety. Most of the gain in EV (over total dependent basic strategy) can be realized in the section labeled "more important"; of less importance are "refinements". Also, the more decks, the less gain.
BASIC HIT STRATEGY - more important (Note: any reference to surrender means late surrender) Hit these hands to a total of 17 or more 8-8 (if not split hit, but surrender if possible) 7-9 (surrender if possible) Any hand that contains 6-6, 6-7, 6-8, 6-9, 6-10 (surrender 6,9 or 6,10 if possible) *(Single deck refinement for hand w/6-6, possibly stand on 15 - see below) Hands other than above - hit to a total of 16 or more *(Single deck refinement - stand on 7,7 or possibly stand on 15 - see below) Hit soft hands to a soft total of 19 or more *(Single deck refinement - stand on soft 18 if hand contains 2-3, 3-3, or 2-2-2 - see below) REFINEMENTS - less important *APPLIES TO SINGLE DECK ONLY - stand on these hands 7-7 (surrender if possible) 5-5-5 4-5-6 3-6-6 1-4-5-5 1-3-5-6 1-2-6-6 1-1-3-5-5 1-1-1-6-6 1-1-1-1-5-6 Hands of soft 18 that contain 2-3, 3-3, 2-2-2 Exceptions - hit to a total of 17 except as indicated 2-2-2-10 2-2-3-3-6 1-2-2-2-3-6 1-1-2-2-10 1-1-2-2-2-2-6 (always hit) 2-2-2-2-2-6 (possible only if dealt from more than 1 deck - always hit) 3-3-10 (hit only if dealt from more than 1 deck, otherwise stand) 1-2-3-10 (hit only if dealt from more than 1 deck, otherwise stand) 2-2-3-9 (hit only if dealt from more than 5 decks, otherwise stand) 1-2-2-2-9 (hit only if dealt from more than 5 decks, otherwise stand) 2-2-2-4-6 (hit only if dealt from more than 6 decks, otherwise stand) 2-4-10 (hit only if dealt from more than 7 decks, otherwise stand)
