Perfect strategy II: low edge, real life

Chapter 6: Perfect strategy · Lesson 19 of 21 · 9 min read

The practical lens. A near-minimum-edge plan that fits your bankroll, your temperament and the table.

Pure math says Don't + max odds. Real life adds budget, nerves and a table full of people. Here's the practical perfect strategy: still near the minimum edge, and built for an actual evening.

The core plan (right side)

  1. Pass Line at the table minimum.
  2. Take odds: the maximum if your bankroll allows, otherwise 2× (0.61%) or 1× (0.85%). Prefer smaller flat bets with more odds over bigger flat bets with less odds.
  3. Want more numbers working? Add one or two Come bets with odds. Or, as the acceptable alternative, place the 6 and 8 in $6 units (1.52%, and quick, with no waiting for a bet to travel).
  4. Want the 4 or 10? Buy them for $20 or more (1.67% with vig on win). Never place them (6.67%).
  5. Skip the Field, Big 6/8, hardways and every center bet.

Do or Don't?

Right (Pass/Come) Dark (Don't Pass/Don't Come)
Edge with full odds 0.37% 0.27%
Feel Win with the table; big cheers on hot rolls Win against the table; quiet celebrations
How results come Many small losses, occasional big wins Many small wins, occasional big losses
Money needed for full odds Smaller (odds ≤ 5× the flat bet) Larger (lay 6× the flat bet)

The difference is 0.1% of action. In dollars it's about $0.15 an hour at $10 ($4.19 for Pass vs $4.04 for Don't Pass). Choose the side you'll enjoy and stick to it calmly.

Session planning, at a $10 table (about 100 rolls an hour)

Plan Edge per $ bet Expected cost/hour Typical hourly swing Bankroll for ~1 hour
$10 Pass, no odds 1.41% $4.19 ±$55 $100–150
$10 Pass + 2× odds 0.61% $4.19 ±$155 $300–400
$10 Pass + 3-4-5× 0.37% $4.19 ±$265 $500–800
$10 Don't + 6× lay 0.27% $4.04 ±$265 $500–800
$6 Place 6 + $6 Place 8 1.52% $3.91 ±$50 $100–150

Plan rules that work:

  • Decide your bankroll before you sit down, and make your odds level fit it.
  • Set a loss limit (for example, the whole session bankroll) and a time limit.
  • A win goal ("I'll stop if I'm up $200") doesn't change EV, but it makes good nights end as good nights.
  • Comps: casinos rate your play by bet size and time, usually at an average edge, and often without counting odds. A small flat bet with big odds gets you cheap action and decent ratings.
Show the math: Behind the planning table

Expected cost/hour = $10 × 1.414% × 29.6 decisions ≈ $4.19 for every Pass plan (odds add 0); Don't = $10 × 1.364% × 29.6 ≈ $4.04, so the hourly gap is $4.19 − $4.04 = $0.15; Place 6 + 8 = $12 × 0.463% × 70.4 rolls ≈ $3.91. Swings and bankrolls come from 40,000 simulated 100-roll hours (see lesson 15). "Bankroll for ~1 hour" ≈ the 7%-to-under-1% risk of ruin range.

Quiz

You can afford $10 Pass with 2× odds, or $20 Pass with no odds. Which has the lower expected cost?

  1. $20 Pass, no odds
  2. $10 Pass + 2× odds
  3. Equal
  4. Can't tell
Show answer

B: $10 Pass + 2× odds. Expected cost comes from the flat bet: $10 costs half of $20, and odds are free.

Quiz

You want action on the 6 and 8 right away. The best practical choice is...

  1. Big 6 and Big 8
  2. Place 6 and 8 in $6 units
  3. Hard 6 and Hard 8
  4. Buy 6 and 8
Show answer

B: Place 6 and 8 in $6 units. Place 6/8 at 1.52% beats Buy 6/8 (2.27%), Big 6/8 (9.09%) and hardways (9.09%).

Quiz

The main cost of choosing Pass over Don't Pass (both with full odds) is...

  1. Huge, avoid Pass
  2. About 0.1% of action, around 15¢ an hour at $10
  3. Nothing, they're equal
  4. Pass is cheaper
Show answer

B: About 0.1% of action, around 15¢ an hour at $10. 0.37% vs 0.27% per dollar bet; in dollars, $4.19 vs $4.04 an hour. A small price for many players' preference.
