Methodology

Ranges: the 6-max 100bb preflop solve (6max_100bb). SRP: BTN RFI raise (entry 3) vs 3BET node call (entry 21, BB facing the BTN open, SB folded). 3-bet pot: 3BET node raise (entry 21, BB facing the BTN open, SB folded) vs call vs BB 3-bet (entry 18, the export's adjacent squeeze branch) × BTN RFI reach (entry 3). Frequencies decoded byte / 200 (preflop_lines_data.bin).
Equity: Monte Carlo over 20,000 frequency-weighted combo pairs per cell, each pair resolved by exact enumeration of all 820 turn–river runouts with the same evaluator that powers the equity calculator. Ties split.
Class shares: exact — every combo with weight > 0 is classified on the flop (Omaha two-plus-three rules) and weighted by its range frequency. No sampling.
