KO (Knock-Out) Blackjack System App & Trainer

The Knock-Out (KO) system is brilliant because it removes the hardest part of card counting: converting to true count. But even with a simplified system, you can lose your edge if you lose the running count.

The Solution

Protocol 21 is the premier tool for unbalanced systems like KO. Unlike other apps that force you to calculate true counts, Protocol 21's KO preset respects the Unbalanced nature of the system. It knows the pivot points and betting correlations, allowing you to train exactly as you would play.

How to Practice KO

To become lethal with KO, follow this Protocol 21 routine:

• Step 1: The Initial Count. KO doesn't start at 0. Use our 'Setup' feature to practice starting your count at the correct negative number based on the number of decks.
• Step 2: Pivot Point Drills. The 'Key Count' mode drills you on identifying when to raise your bet. We simulate long shoes so you get used to the count drifting upwards.
• Step 3: Speed Runs. KO is about speed. Use the 'Speed Drill' to push your recognition time to under 0.8 seconds per card.
