Hippopotamus Defense
Overview
Hippopotamus Defense is a specific line in the Semi-Open Games family (ECO B00), arising from a recognised theoretical position.
The Semi-Open Games group covers semi-open games — replies to 1.e4 where Black declines the symmetrical 1…e5 in favour of an asymmetric pawn structure.
It begins with 2 plies and takes 1. e4 Nh6 to reach the canonical position.
The line is a first-level refinement of King's Pawn Game.
It continues primarily into one named line, Hippopotamus Defense.
