CO Facing 5-Bet Shove GTO chart, 100bb

Cutoff (CO), 100 big blinds deep, six-handed. You made a 4-bet and someone shoved; do you call or fold? The chart says how often to raise, call or fold each of the 169 starting hands.

Source: Solver output at 100bb chipEV with no ante. CFR over the 6-max preflop tree (opens, 3-bets, 4-bets, 5-bet jams, cold calls and squeezes) on the 169 hand classes, with showdown equity from the preflop equity table. Equity realization factors: in position UTG 1.15, MP 1.15, CO 1.16, BTN 1.20, BB 1.05; out of position UTG 1.00, MP 0.96, CO 0.92, SB 0.90, BB 0.89; pairs 1.00, suited 1.06, offsuit 0.92, less 0.05 a gap; equity raised to the power 1.30 so weak hands realize less. Pots that are all in use plain equity. Approximate: a preflop model of postflop play, not a full postflop solve. How the charts are made
