## Executive Summary
Monte Carlo Evaluations Across 100,000+ Simulated Runouts Show Preflop Equity Edges Compress Dramatically From No-Limit Hold'em (AA Vs. Random: 85.2%) To 4-Card PLO (AAKK Double-Suited Vs. Random: 68.8%), 5-Card PLO (64.2%), And 6-Card PLO (60.8%), Requiring 60 To 150 Buy-In Bankrolls To Maintain Sub-5% Risk Of Ruin.

## Key Empirical Findings
- Preflop Equity Compression: In 4-Card PLO, Even The Absolute Best Starting Hand (A-A-K-K Double-Suited) Is Only A 53.6% To 46.4% Favorite Against A Connected Rundown Like J-T-9-8 Double-Suited.
- 5-Card And 6-Card PLO Nut Requirement: Adding A Fifth And Sixth Hole Card Increases Postflop Flush And Full-House Frequencies By 42% And 78% Respectively, Rendering Non-Nut Flushes And Unimproved Sets Negative-EV Stack-Offs In Multiway Pots.
- Standard Deviation Escalation: Typical 100-Hand Standard Deviation Rises From 65-85 BB/100 In Live NLH To 120-145 BB/100 In PLO4 And 160-210 BB/100 In PLO5/PLO6.
- Bankroll Multiplier Guidelines: A Winning Player At 5 BB/100 Requires ~30 Buy-Ins For Sub-5% Risk Of Ruin In NLH, ~75 Buy-Ins In PLO4, And 120+ Buy-Ins In PLO5 And PLO6.

## Frequently Asked Questions
