The Keres Defence (also known as the Kangaroo Defence or Franco-Indian Defence) is a chess opening characterised by the moves:
1. d4 e6 2. c4 Bb4+
The opening is named for Estonian grandmaster Paul Keres. This opening was known since the 1840s and was played by Henry Thomas Buckle in his fourth match game with Johann Löwenthal, London 1851. The standard reply today, 3.Bd2, was recommended by Howard Staunton.
White can respond 3.Nc3, 3.Nd2, or 3.Bd2. The game often transposes to a Nimzo-Indian Defence, a Dutch Defence, a Queen's Gambit Declined, an English Defence, or a Bogo-Indian Defence.
