Four rivals · One fair search budget

Choose the mind
across the grid.

Every rival uses the same public rules: no hidden hands, no future deals, no private outcome oracle. At a given table size they share the same responsive candidate budget; what changes is the board-reading tool they bring to a position.

Pick a challenge, not a percentage: these dossiers describe live decision habits and the situations where each rival becomes dangerous.

01 / RivalPortrait of Alai, an OverGrid AI opponent

easy

Alai

Keep three doors open.

The readable legacy rival: an expansive broad frontier that keeps several ordinary routes alive instead of forcing a sharp tactical decision.

Board-reading tool
Frontier optionality
Watch for
A wide, low-commitment frontier that remains easy to read.

A deliberately legible legacy rival, not the sharpest conversion tool.

Why names alone were not enough
02 / RivalPortrait of Petra, an OverGrid AI opponent

medium

Petra

Turn a route into a summit.

The reliable converter: turns reachable height into banked points through compact routes, then asks whether the route can hold.

Board-reading tool
Bankable height routes
Watch for
A reachable peak with compact support and a route worth finishing.

Can surrender breadth to make a dependable conversion.

The playtest that caught a missed peak
03 / RivalPortrait of Ender, an OverGrid AI opponent

hard

Ender

Advance while taking away the reply.

The duel reply controller: spends deeper search where the rival answer matters, choosing pressure that still makes sense after the strongest public reply.

Board-reading tool
Reply-backed position value
Watch for
A move whose advantage survives the strongest plausible public answer.

Spends more thought where a reply can overturn the obvious score.

Ender’s two-lane command
04 / RivalPortrait of Bean, an OverGrid AI opponent

Wild

Bean

Make the board answer two threats.

The wild fork hunter: creates two live demands, chases asymmetric upside, and keeps a bailout route when the jackpot line is refuted.

Board-reading tool
Forcing forks and bailout routes
Watch for
Two disconnected demands that one reply cannot erase together.

Accepts exposed structure when the upper tail is genuinely alive.

Bean’s two-threat fork

Alai is the useful control. Petra converts. Ender tests replies. Bean makes you solve two problems at once. Their histories are public, including the failed ideas that changed them.
