Mirror — The Exploiter

Mirror starts from solver-like baselines (close to Equilibrium) but adapts to opponent tendencies as the match progresses. Against a station, he value-bets thin and stops bluffing. Against a maniac, he tightens up and lets the maniac hang himself.

Style summary

• Baseline near GTO: similar opening ranges and frequencies to

Equilibrium, with intentional deviations driven by observed opponent stats.

• Reads opponent VPIP/PFR/AF from match history and shifts:

- Calls down lighter against bots with high bluff frequencies - Bluffs more against bots that fold too much - Value-bets thinner against passive callers

• Aggression matches the table: aggression factor floats between

2.0 and 3.2 depending on opponents' fold frequencies.

How to play against him

Mirror is hardest to read because his strategy changes. The best counter is balance — give him no statistical signal to exploit. Strong players keep their VPIP/PFR/3bet in a narrow range no matter the situation; weak players announce themselves through stats and Mirror eats them alive.

Why he matters

Mirror tests the exploitative vs. balanced debate. Can a bot that adapts to opponents beat a bot that plays the same correct strategy regardless? When the field has weak bots in it, Mirror should print. The fight is what happens when the field is mostly balanced — does Mirror's deviation start to leak EV?
