For the benefit of other readers, the full set of rules is: Single deck. Dealer stands on soft 17. Winning blackjack pays even money. Player may double any first two cards. No double after split. Player may resplit to four hands, including aces. No draw to split aces. No surrender. Six-card Charlie (player unbusted six cards automatically wins). Cards shuffled after every hand. If game runs out of cards, all unbusted player hands automatically win. The house edge using total-dependent basic strategy is 2.13%. I ran a 7-player simulation, using total-dependent basic strategy, and the average number of cards used per round was 21.65, with a standard deviation of 2.72. In almost 190 million rounds played, the most cards ever used was 42, which happened 7 times. It is my educated opinion that even with computer perfect composition-dependent strategy the player would still realistically never see the last card. You could cut down the house edge much more using composition-dependent strategy, according to all the cards seen as you go along. However bucking 2.13% house edge to start with, you’ll never get anywhere near break-even, regardless of how hard you try.
