The Machine's book

Every character in the league plays with its own hand matrices: its range for every spot, extracted from its own play and sealed in the vault. This one is public. The Machine holds the challenger seat, the seat the audience will compete for, so its book is the one a challenger has to beat, and you should be able to read it.

Version 2, source "observed", from 33,609 decisions over 17,476 hands in 92 sessions. Sealed as ac2a105098ce590b… in the league's hash-chained ledger. Each square is a starting hand; its colour is what The Machine does most often there, its number how often. Hover a square for the counts. Grey is fold, blue call, orange raise, red jam. Nodes with fewer than 30 decisions are left out.

How to read a node: position, then what the action looked like before The Machine acted, then the effective stack in big blinds. Every other character's book stays sealed. The solver's own preflop strategy is on the book.
