From Count to Bet

True count conversion

A running count of +5 means very different things depending on how many cards are left. Spread across six decks it is weak. With one deck left it is strong. The true count fixes this:

True count = running count ÷ decks remaining

You estimate decks remaining from the discard tray. If two decks have been dealt from a six-deck shoe, roughly four remain, so a running count of +8 is a true count of about +2. Deck estimation is a skill of its own, and the true count drill targets it directly.

The bet ramp

Your bet rises with the true count. A common shape ties the bet to the true count minus a threshold, in units. Below is the sample ramp built into the trainer, which you can replace with an engine-produced ramp for your exact rules, penetration, and spread:

With this modest one-to-eight spread over the counts our engine measured, about 50% of the total money you bet lands at a true count of +2 or higher, which is exactly where the player edge lives. That is the whole point of a ramp: get more money down when the odds have already turned.

Unit sizing

A unit is a fraction of your bankroll, not a random chip value. Bet too large a fraction and normal variance can wipe you out even with an edge. The size of a correct unit follows from your edge and your tolerance for risk of ruin. Because that edge is small (single-digit tenths of a percent, as the house edge page shows), a unit is a small slice of a bankroll that must be large enough to absorb long losing stretches.

Spread size

A bigger spread (say one to twelve units) captures more edge than a small one (one to four), but it is also the most obvious tell a counter has. The right spread balances edge against the risk of being noticed and barred.

Back-counting (Wonging)

Instead of playing every hand, you watch a table without betting and only sit down when the count is already favorable, then leave when it drops. This raises your average edge because you skip the negative counts entirely. It also stands out, because a player who only appears during good counts is easy to spot.

Managing attention

Casinos watch for the pattern of a counter: minimum bets during poor counts and large bets during good ones, especially bets that jump right as the shoe gets deep. Counters use cover, such as occasional bets that do not match the count, consistent demeanor, and shorter sessions, to reduce heat. Cover costs a little edge, and how much to use is a judgment call.
