i have been advised that the player has an advantage in a 6:5 single deck game when the true count is higher than the number of aces remaining in the deck. in this case since getting a blackjack does not pay much and is not an issue, the important thing is to bet big when the dealer is likely to bust.
e.g.: the true count is +4 with 0 aces remaining, there is no chance of blackjack anyway so the 6:5 payout on bj is not an issue. the dealer is more likely to bust here, in the theory, so we can bet big. one could use a 2 level or 1 level count. for uston's advanced +/- in theory this should also work, i think. this extreme example can be extended to other true counts and number of remaining aces when true counts are higher than number of aces remaining.
please advise.
