If I understand what you are saying, not totally clear, but if 1 deck left and no aces out and tc 6 I would spread to 2 and max it. I play with ls and s-17 so I feel very secure in doing that. Be prepared for the dealer to pull a good hand also.
No I not not clear enough. TC is at 6 purely from the richness in aces, this is UAPC and the tc is adjusted for betting purposes. The running count and the true count for strategy is flat zero.
