Ace/Five
A balanced betting count: fives are +1, aces are −1, everything else is 0. A full deck sums to zero.
The values
How the values work
Ace/Five is the two-rank betting count popularized in modern explainers (including Wizard of Odds). It is related to, but not the same as, Thorp’s and Revere’s five-count ideas — those counted fives only. Ace/Five counts both ranks, which is why it balances: four fives and four aces per deck.
Use it as a betting count. It is not a playing-strategy count. Do not paste Revere Five Count efficiency numbers onto this map — those describe a different system.
+1
5
Fives. When they leave, the remaining shoe is better for the player.
0
2, 3, 4, 6, 7, 8, 9, 10, J, Q, K
Ignored.
−1
A
Aces. When they leave, blackjacks get scarcer.
The math
Running count, then true count
Start at zero
Ace/Five is balanced. Start at 0. Four fives at +1 and four aces at −1 cancel over a 52-card deck.
True count is still running count divided by remaining decks if you want a per-deck betting number. Many players just raise the bet when the running count is high in a shoe game.
Efficiency
Why the numbers look like that
We do not publish BC, PE, or IC for Ace/Five. Revere’s five-count tables (~BC .43 / PE .15) describe fives only. Wizard of Odds and other Ace/Five write-ups do not agree on a second corroborated table for aces and fives together, so the locker shows —.
