I am relatively new into this ( 6 months or so). I only play Double Deck ($25 Table Min) with H17, no RSA, Double on any 2 cards, Double after Split, no surrender, Pen 65-70%. I use Hilo with Ace side count. So far I am using Ace count for two things:

1. Insurance decision - I ignore Aces for Insurance decision. If I have a running count of 4 with 4 Aces gone and 1.5 Deck left my TC for insurance decision is (4+4)/1.5=5.3 and if this count is >3 I buy full insurance on all hands. Is this index correct?

2. Max Bet Decision - If I have a high count but remaining Aces are less than average (1 per 1/4 deck etc.) then I do not put max bet. On a monster count, I will always put my max bet but I am talking about borderline decisions. Is this correct?

What are other uses of Ace side count with HiLo counting?
