The Hippopotamus Defence is a chess opening system employed by Black, consisting of a double fianchetto structure (bishops on b7 and g7) and a small pawn centre (pawns on d6 and e6). The knights are typically developed to e7 and d7 and the rook's pawns to a6 and h6. [ 1 ]

The white rooks form a battery to capture the pawn protecting the black king. A battery in chess is a formation that consists of two or more pieces on the same rank, file, or diagonal. It is a tactic involved in planning a series of captures to remove the protection of the opponent's king, or to simply gain in the exchanges .
