Introduction

Canfield Master is an ace-neutral counting system created by Casper Fisher in 1962. It combines simplicity and power by tracking aces separately.

Theoretical Foundations

  • 1962: Casper Fisher develops Canfield Master.
  • Basis: Unbalanced values and side-count of Aces.
  • Requirement: Know basic strategy and track every Ace.

The key is to neutralize Aces to keep precision without making things harder.

How It Works

Each card has a preset value; the True Count is calculated by dividing the Running Count by the number of decks remaining.

Cards 4–6: +2
Cards 2–3–7: +1
Cards 8–A: 0
Card 9: −1
Cards 10–J–Q–K: −2

True Count = Running Count ÷ Decks remaining

When to Raise Your Bet?

Wait until the True Count turns positive; many players raise their bets once it hits +1 or higher.

  • +1: 1 base unit
  • +2: 2 units
  • +3 or more: adjust based on your risk tolerance

Always vary your bet discreetly to avoid suspicion.

Example: if your base unit is 1, bet 2 at +2. The penalty from high cards makes staying positive even more critical.
