scenario:

at the start of the shoe,dealer burn the cards off the deck depending on the value. dealer burns a card and take the hole card after everyone has played their hand .rules are h17,das,late surrender. no discard rack and the shoe is in a black casing with cover on top.the only way i could think of how far the shoe is, is to count the cards played. is KO the most suitable count for this conditions since it does not require true count conversion? or should i stay with BS, no counting.thanks for all your responses.
