Basic Strategy - ENHC.

Below is the basic strategy chart for the most common Blackjack ruleset offered in UK casinos: 6 Deck, S17, DOA, DAS, RSA.

6 Deck (although this strategy chart is valid for 4 and 8 deck games),
S17 (dealer stands on ALL hands of 17),
DOA (double on anything, you may double down on any hand),
DAS (double after split - doubling down after splitting to two hands is allowed),
RSA (Resplit aces. Re-splitting of aces is allowed if you split two aces and you receive another ace on one or both of the hands).

This ruleset leaves the player playing at a 0.55% disadvantage (HE), assuming correct basic strategy is applied.
