Hi-Opt II
A level-two ace-neutral count from Humble and Braun. Fours and fives are +2; tens are −2; aces stay outside the running count.
The values
How the values work
Hi-Opt II is the level-two successor to Hi-Opt I, associated with Lance Humble and Julian Braun. It stays ace-neutral. The extra +2/−2 ranks buy playing efficiency and insurance correlation at the cost of more mental work.
Published practice still uses an ace side count for betting, same idea as Hi-Opt I.

The ace side count
Ace side count
Published practiceAces stay outside the level-two running count. Side-count them for betting; use the primary true count for strategy.
Tally aces as they leave the shoe. Remaining aces versus remaining decks tells you when to raise the bet. The primary true count still drives playing deviations.
The math
Running count, then true count
Start at zero
Start at 0. The level-two values still balance over a full deck. Aces do not move the running count.
Divide by remaining decks for a true count. Side-count aces if you are using this as a betting count.
Efficiency
Why the numbers look like that
Level two shows up in the PE and IC. You pay for that with more ranks to keep straight under speed.
BC
91%
Betting correlation
Betting correlation of 91% on the primary count — still short of Hi-Lo unless aces are side-counted.
PE
67%
Playing efficiency
Playing efficiency of 67%, among the strongest maps in the locker.
IC
91%
Insurance correlation
Insurance correlation of 91%. Tens at −2 are a loud insurance signal.
