Bet Spread: The Part That Actually Makes the Money

Updated

Counting cards produces information. The bet spread is what turns it into money. A counter who tracks the shoe perfectly and bets the same amount every hand earns exactly nothing — and a wide spread is also the single thing that gets people barred.

The short version
Every figure here is computed with our own solver and checked against an independent reference. The calculator applies the same numbers to your table.

Why it is the whole game

Your edge at a true count of 0 is about −0.34%. At +3 it is about +1.18%. If you bet the same in both, you are averaging a losing number with a winning one and mostly getting the losing one, because low counts are far more common.

Betting eight times as much at +3 as at 0 is what makes the winning hands count for more than the losing ones. Everything else in counting exists to tell you when to do it.

This is the ramp used for the earnings figures elsewhere on this site.

How wide, and what it costs you

Wider is mathematically better and practically worse. A 1–4 spread is inconspicuous and earns little. A 1–16 spread earns well and is obvious to anyone watching bet sizes, which is precisely what surveillance watches.

1–8 is the usual compromise for a single player at a shoe game. Below that the edge is too thin to survive the variance; above it you are relying on not being observed.

Team play exists to escape this trade-off entirely: the big player has no ramp at all, because they arrive already betting large.

Making it look natural

A ramp that tracks the count exactly is a signature. Real counters blur it: rounding bets to natural amounts, occasionally leaving a large bet out for one extra hand, raising after a win rather than after a count change.

Every one of those costs a little expected value and buys time. Which is the right trade depends on whether you would rather earn 5% less per hour or be asked to leave in an hour instead of a month.
