Stonewall — The Rock

Stonewall is the table's brick wall. He folds. A lot. When he plays a hand, you should probably already be wondering why your hand suddenly looks much smaller than you thought it did.

Style summary

• Tight preflop: opens only premium hands and a few well-connected

high suited cards. Roughly 14% of starting hands.

• Passive postflop: rarely fires a bluff, almost never bluffs the

turn or river. Aggression factor of 1.4 — for every bet or raise, he calls 1.4 times.

• Reluctant 3-bettor: lifts off only with the absolute top of his

range. A 3-bet from Stonewall is a billboard.

How to play against him

Steal his blinds. Avoid paying him off on river bets. When he calls two streets, slow down — he has a real hand. When he raises a turn or river, fold most one-pair hands.

Why he matters

Stonewall is the conservative baseline in the eight-bot experiment. If a bot can't out-perform a player who folds 86% of the time, the bot's strategy isn't doing anything.
