Basic Strategy and Charts

Why Card Counting Works

High cards (10, J, Q, K, A) favour players, more blackjacks, doubles, dealer busts. Low cards (2-6) help casinos. Card counting tracks the undealt cards.

Running count starts at 0. Positive = player edge (bet up). Negative = house edge (minimum bets). True count divided by decks left for precision.​

Edge math: True count +1 = 0.5% player advantage. +5 = 2.5%. Counting cards in blackjack makes the impossible routine.

Opinion of Andrew Collins

“Casinos shuffle winners away. Counters ramping £5 to £100? Quiet profit machines.”
Blackjack Hi-Lo card counting chart: low cards (2-6) +1, neutral (7-9) 0, high (10-A) -1.

Hi-Lo System: Industry Standard

Hi-Lo tracks high/low cards with simple values. Scan every dealt card systematically.

Hi-Lo values:

  • 2,3,4,5,6 = +1 (low cards gone = good)
  • 7,8,9 = 0 (neutral)
  • 10,J,Q,K,A = -1 (high cards gone = bad)

Start counting every dealt card. Multiple-deck shoe:

Hand‎ Cards Dealt‎ Running Count‎
1 1 5,K,3,8 +1
2 2 10,A,2 +2
3 3 7,9,6 +3

Opinion of Andrew Collins

“Casinos thwart card counters. Ramp £5 to £100 on positive count quietly.”

Running Count to True Count Conversion

True count = running ÷ decks remaining. Essential for bet spread accuracy.

Example: Running +6, 3 decks left = True +2 (1% edge).

Bet ramp (1-20 spread, £10 tables):

True Count‎ Bet Size‎
1 < +1 £10 minimum
2 +1 to +2 £40
3 +3 to +4 £80
4 +5+ £200 max*

*Typical table max in UK land-based.

Real-world result: £20-50/hour solo play with discipline.

10-Minute Daily Practice Drills

Drills build speed + accuracy to second nature. 10 mins/day = table-ready in 2 weeks.

  • Drill 1: Deck speed: Count single deck aloud. <25 seconds = table-ready.
  • Drill 2: Shoe estimation: Deal 2-deck shoe, call true count every 20 cards.
  • Drill 3: Bet simulation: Paper-track bets by true count progression.

Camouflage drill: Count while walking/conversing. Super sharp memory beats casino scrutiny.

Free practice: Master Hi-Lo speed using our blackjack simulator.

Global Casino Countermeasures

Casinos spot card counters via bet spread, deviations, and session length. Regional traps:

Las Vegas:

  • Continuous Shuffle Machines (CSM, edge killer)
  • Casino surveillance, Facial recognition + pit boss "heat"

UK Land-based:

  • Dealer shuffles after +count
  • 6:5 single-deck game traps

Europe/Macau:

  • AI eye-tracking cameras
  • Table maximums raised mid-shoe

Opinion of Andrew Collins

Pit Dodges: Negative count? Same amount bets. Positive count? Tip dealer, act recreational.”

AI as the New Pit Boss

Bet Spreading: Profit Mechanics

Bet size by true count maximises edge over the house. 1-20 spread (£10-£200):

  • Kelly Criterion: 1% bankroll per true count unit (£10K roll to £200 max)
  • Risk of ruin: <5% disciplined play
  • Wonging: Back-count hot shoes (+50% hourly, double heat)

Playing Deviations: True Count Triggers

Use basic strategy, adjust per true count:

  • TC +3: Insurance ON (player edge flips)
  • TC +4: 16 vs 10 = STAND
  • TC +5: 12 vs 4 = STAND

Illustrious 18 deviations capture 80% advanced gain.

Fatal Beginner Mistakes

90% fail here - dodge these traps for profit.

  • Speed failure: Drill decks religiously
  • Spread too wide: Solo: 1-10 maximum
  • No acting: Bet drunk, lose small on purpose
  • Ignoring heat: Pit boss chat = exit signal
Andrew Collins

Opinion of Andrew Collins

“Traps sink rookies. Precision keeps you winning.”

​Final Word

Card counting beats blackjack legally when executed with discipline. That £10K bankroll becomes a £20/hour reality: treat it like precision darts, not lottery tickets. Card counting uses skill, not cheating: it's informed play within the rules.

Andrew Collins

Opinion of Andrew Collins

“True count +5 = monster catch. Spot traps, cash quietly, swim away winner.”

Card Counting Questions Answered

What is pro counting speed?

Deck in 25 seconds marks pro level. Beginners target 45 seconds, dropping 5 seconds weekly through drills. Speed builds second-nature accuracy.

Can beginners use Hi-Lo?

Yes, Hi-Lo's simple +1/0/-1 values build second nature fastest. Perfect first system before Zen or KO. Industry standard for good reason. Simple count for blackjack game newbies.

Is online blackjack countable?

No, continuous reshuffles and RNG kill edge. Live dealer streams sometimes work, but pit bosses watch screens. Stick to physical tables.

What bankroll for £10 tables?

£10K minimum. Risk 1% per session (£100) supports 1-10 spread up to £200 max bet. Kelly Criterion halves risk, doubles longevity.

Is insurance smart at true +3?

Yes, at +3 true count, insurance flips to player edge. Take it every time; it's your second biggest money-maker after big bets.

Can solo beat team play?

Solo 1-10 spread earns £25/hour with lower heat. Teams are complex with trust issues and higher casino bans. Solo scales cleaner long-term.

How to camouflage card counting?

Bet high variation smoothly, act casual, tip dealers generously, and play hands individually slowly. Blend as a recreational player; surveillance flags robots, not relaxed winners.
